Log house, Canadian technology. Canadian log house or "Canadian bowl" log house. Post ® beam technology
Hybrid Post ® Beam technology, introduced in Canada just about 20 years ago, combines traditional Canadian logging with the Post ® Beam log frame construction technique, significantly expanding the capabilities of architectural design facades.
In the simplest version of using hybrid technology, a log first floor is built using classical Canadian cutting, and the attic and porch of the house - using the frame method Post ® Beam. However, in Lately Both construction methods are increasingly being combined within the same floor.
CANADIAN CUTTING
Wooden house construction in North America its origins owe to emigrants from the Old World, who used European traditions and construction methods.
IN new technology(the first standard regulating it was dated 1976, the latest - 2012) the marking system, joint design and principles of combating shrinkage from the Norwegian felling system were taken as a basis, but the log house was made not from a gun carriage, but from a round log.
Thus, Canadian logging is considered to be a kind of symbiosis of Norwegian and Russian methods making corner connections.
The Canadian cup has a trapezoidal saddle shape. On the upper part of the lower mating log, two cuts are made at an angle of D5-500 ( exact value depends on the diameter).
The minimum length of the cleats is two log diameters, the maximum width of the top of the seat saddle is 90 mm. A correspondingly shaped groove is cut out in the upper mating log, the depth of which must be at least 25 mm greater than the height of the saddle.
As a result, a so-called saddle gap is formed above the top of the connection of the lower log with the upper one, which will disappear when the mating crowns shrink as a result of wood shrinkage. Canadians for a long time limited themselves to a similar cup, which makes it possible to obtain a fairly strong and dense self-jamming connection called “into the saddle”. But it had one drawback - it did not prevent the wood from twisting when drying.
That is why later a special tenon was introduced into the design of the castle, cut into the bowl of the upper mating log, and a corresponding groove was provided at the top of the lower saddle. (According to some experts, the tenon also helps reduce the ventilation of corner joints, but not everyone agrees with this thesis). Then another innovation appeared - they began to make a saddle-shaped lock not only at the top, but also at the bottom of the log, resulting in the so-called diamond bowl. As a result, today there are three options for connecting to a Canadian cup: with bars (“in the saddle”), with bars and a tenon, as well as with upper and lower bars and a tenon.
Another feature of the Canadian felling is the original shape of the longitudinal grooves in the mating logs. So, in the lower part of the upper log, a double groove (doublegroove) in the shape of the letter W is cut, and in the upper part of the lower log, a single groove (veegroove) in the shape of the letter V is cut.
True, domestic carpenters, gradually mastering a new technology for themselves, abandoned the use of both, replacing these grooves with a lunar semicircular groove, more familiar to Russian cutting, but with sharp lower edges (as in Finnish or Norwegian cabin), which allows you to reliably cover the inter-crown insulation inside the groove from bad weather. The width of such a groove, as a rule, is at least 12 cm, but can reach up to % of the diameter of the log, making the connection much warmer than in the Canadian version.
Types of log corner cuts
1. Russian felling
The connecting bowl is located at the bottom of the top log, which makes the corner joint more resistant to precipitation
2. Russian fat tail cutting
It has an improved bowl with a special spike - fat tail. WITH opposite side log, a groove is created for the tenon of the next log
3.Norwegian cabin from gun carriage
Reminiscent of fat-tail cutting, but the bowl is formed by inclined cuts, thanks to which, when the wood dries out, the joint self-seals under the weight of the crowns
4.Canadian log cabin
A symbiosis of Norwegian and Russian fat-tail cutting - inclined edges and a groove for a tenon are created on the top of the log, which is located in the lower bowl of the upper log
POST® BEAM TECHNOLOGY
The Canadian Post ® Beam logging is essentially a direct descendant of the now almost forgotten Russian logging (in a post, in a rack, in a lock), in which the frame of the building is assembled from vertical posts with grooves selected along them. Logs are inserted horizontally into the latter, at the ends of which spikes corresponding to the geometry are pre-cut.
In this case, a longitudinal recess is made in the lower part of each horizontal log, filled with a compactor (moss, tow, etc.), as in other types of Russian felling. But if in Rus' the space between the log stands was usually filled with so-called whips (thin tops of trunks), and similar technology was used mainly for the construction of unheated outbuildings, then in Norway, and then in Canada, residential buildings were successfully built along it.
The difference was that in Norway a carriage was used to fill the spaces between the posts, and in Canada rather thick logs were used (their diameter was at least 300 mm).
And the posts themselves in the Canadian version of the felling have become more powerful - their diameter physically cannot be less than 400 mm, since in the area where the filling logs adjoin them, it is necessary to make cuts on the posts with a width of 200 mm. Application of logs large diameter- this is not only a tribute to fashion and beauty, but also an opportunity to reduce the number of crowns of a log structure, which, in turn, reduces heat loss through the walls.
It should be noted that in the Post ® Beam technology, the openings between the posts can be filled not only with logs, but also with insulated frame structures, blocks (including those made of foam materials), as well as glass. The wall frame is firmly connected with the equally powerful slab roof structure, forming almost a single whole with it.
Left: Canadian bowl - traditional version It involves making ridges (“cheeks”) only on the top part of the log. Suitable for joining logs of any diameter, and especially for combining small and large diameter logs
Right: Canadian Diamond Bowl
The notches are made on the upper and lower parts of the log; the result is a more labor-intensive, but unusually beautiful connection. Only suitable for joining large diameter logs
CANADIAN CUTTING - CONSTRUCTION PROCESS
Manufacturing necessary elements and preliminary assembly of the house, the design of which combined both log and frame technology, were produced on a specially equipped construction site located near timber harvesting sites.
Thus, it was possible not only to select the most suitable blanks for each structural element, but also to control the work of carpenters at all stages, and in addition, to use lifting equipment without time restrictions. But the main advantage of such an organization of work is the following.
Structures of this type are built using not only Canadian cups, but also grooves and tenons of a wide variety of shapes and sizes, which must be carefully (and therefore long) carried out and scrupulously adjusted to each other, otherwise the house will be impossible to assemble.
That is why the production of log and frame elements and preliminary assembly take many months. However, the customer is not present at preparatory stage, but only watches how the skeleton of a future house is assembled on his site in just a few days from brought logs.
Upon completion of the work, the builders marked each structural element and drew up an assembly diagram (it is a necessary appendix to the construction contract). The frame was then dismantled, packaged and transported to the client’s site, where it was reassembled, but now on a foundation, which was a monolithic slab.
The log house was mounted on wooden dowels, imparting rigidity wall structure. When installing the roof, we used technological techniques and details that allowed the elements rafter system slide freely relative to the log walls during shrinkage of the log house.
The progress of the construction of a house made of Siberian cedar logs with a diameter of 35 to 100 cm is presented in sufficient detail in the photographs, so we will comment only on the stage of constructing the roof, which remained “behind the scenes”. A continuous flooring of planks was built on top of the rafters, thus creating a ceiling.
Through the vapor barrier, in increments of 60 cm, boards with a cross section of 200 * 50 mm were nailed to it, installing them on a narrow edge. In the cavity between the boards, slabs of mineral wool insulation with a total thickness of 200 mm were laid in layers, covered with a vapor-permeable membrane, which was pressed to the boards with counter battens with a cross-section of 50 * 50 mm. Next, a pre-treated antiseptic compound was attached to the counter slats. wooden sheathing from a block with a cross-section of 100 x 25 mm, and to the last - a flooring made of metal tiles of the color chosen by the owners.
ADVANTAGES AND DISADVANTAGES OF CANDY CUTTING
As we have already noted, recently in our country there has been increased interest in Canadian logging and the associated Post ® Beam and Hybrid Post ® Beam technologies, about which many laudatory reviews are published. Of course, these methods have certain advantages, but not all of them are absolutely indisputable. Let's start with the advantages of the Canadian logging itself, first of all with its undoubted advantage.
In the Canadian bowl, double-sided cuts are performed only in the lower log. The result is a cone-shaped “saddle”-zamon, which self-seals as the wood dries out. Similar solution eliminates the appearance of cracks in the corners of the log house and eliminates the need for repeated caulking.
But it’s quite possible to argue with other theses.
The Canadian bowl is a stronger and warmer compound than the Russian bowl.
If we compare it with a regular round bowl of notches in the clapper or in the clapper, then the Canadian one is really stronger. However, such cuts as in a fat tail or in a flap with a cut are in no way inferior to it in strength, and a cut in a hook is even superior.
If we talk about the “warmth” of the connection, then with a log diameter of 300 mm, the thickness of the wood at the junction of the logs in the Canadian cup in the narrowest part does not exceed 200-250 mm. The width of the insulation embedded in the saddle gap in this zone is a maximum of 70 mm. The thickness of the wood layer when joined into a Russian bowl is almost equal to the diameter of the log. At the same time, the latter is insulated over the entire area. So which of the two compounds is warmer?
The next statement: it is less labor-intensive to implement. Yes, making a trapezoid with almost flat edges by cutting with a chainsaw is really easier than, as in the Russian version, cutting out a bowl with an axe, adze, or even a chisel.
But let’s not forget that making a Canadian bowl also involves a rather complex double drawing of logs, as well as a large volume manual grinding. That is why the price of Canadian log houses is quite high. It is also necessary to take into account the influence of processing methods on the durability of wood. The saw loosens and “fringes” the surface of the wood, which even after sanding remains vulnerable to the penetration of dampness. The ax smoothes the outer layers, closing the pores, which prevents moisture from penetrating inside the product. So which option is better?
Now about Post ® Beam technology. Like all frame methods construction, it allows you to build houses on permanent place their location with greater speed (assembly lasts 1-2 weeks). And start finishing walls can be installed immediately after the installation of the frame is completed (the structure is not subject to shrinkage).
But if we talk about the Hybrid Post ® Beam technology, in which a log structure is combined with a frame structure, then when they shrink, they will behave completely differently. Of course, the situation can be saved by those installed under each support pillar. screw compensators shrinkage, but only on condition that the need for their regulation will be monitored experienced specialists. In general, the construction of such houses - structurally complex, with elements having a huge mass - should be trusted exclusively to professionals in this technology. Unfortunately, we still have only a few of them.
And yet, the appearance of new technology on the Russian market cannot but rejoice, because it opens up wide opportunities for architects to implement various ideas designed to make each house unusual and even unique, like a work of art. Besides. Hybrid Post ® Beam saves money cash thanks to the use of lighter foundation options ( frame construction lighter than logs) and reducing the start time for finishing work.
DIAGRAMS FOR THE SHRINKING PROCESS OF RUSSIAN AND CANADIAN BOWLS
1. The shape of the bowl partially follows the surface of the lower log. The insulation is laid over the entire area of the bowl
2. The logs are adjusted to each other more accurately. The insulation is placed in the so-called saddle gap
3-4. Both types of cups undergo changes during drying. Depending on the initial moisture content of the logs, their diameter decreases by 5-10 96. Accordingly, the shapes of the bowls and the size of the gaps in them change. The log house begins to settle
5. Large gaps remain at the bottom of the cup, which will have to be caulked with flax jute or tow.
6.At the expense triangular shape bowl, the connection self-seals. No need to caulk
Filling frame walls
The connection of the ends of the horizontal elements with the vertical logs-posts was made using the “tenon-groove” system: the groove was selected in the posts (a), and the tenons were cut at the ends of the filling logs (b). At the bottom of each log, a longitudinal groove was selected, into which final assembly an inter-crown seal was inserted. They also sealed the tongue-and-groove joints.
Additional Information
CLEANING BARK WITH A JET OF WATER
When processing wood, it is important to preserve it natural properties. That is why devices are increasingly being used to remove bark from a log using a pressurized water jet. With this debarking, the metal of the tool does not come into contact with the most important protective layer logs - sapwood and does not damage it. As a result, the wood not only retains the natural beauty and texture of the surface, but also better withstands the effects of environment.
CENTURY TRADITIONS
The main tool of a carpenter, as many centuries ago, is a “draw” - a tool similar to a compass: when marking, one leg slides along the surface of the lower log, the second draws a line on the upper one. Another old one, but just as indispensable tool- an adze with which a longitudinal groove is made. This ax smoothes the outer layers of wood, closing the pores and preventing moisture from penetrating inside the product.
LITTLE TRICKS
It is no secret that when cutting logs across the edge of the cut with a chainsaw, thin chips become overgrown. To prevent their appearance, a simple technique is used - a knife is first drawn along the cut line. In this case, chips may appear only on the cut part of the log
WALL CONSTRUCTION
The specificity of the project under consideration is that: that log (in the Canadian bowl) and frame (Post & Beam) technologies were combined within one floor. At the same time, only two were assembled using the timber method. end walls houses, and the adjacent sections of the walls of the front and rear facades had a combined design: one side was assembled into a Canadian bowl, the other ended support pillar stand, with which the horizontal rims were connected using the tongue-and-groove technology. All others, both external and interior walls the houses were assembled only using the tongue-and-groove system using Post & Beam technology.
Technology of Canadian house cutting - photo
1-4. The process of making a Canadian bowl is as follows: the contours of the notches are marked on the surface of the log, and then they are made using a chainsaw (1). The surface of the webbing is thoroughly polished (2), then the contours of the groove for the fat-tail tenon are marked on the upper edge of the saddle, cut out using a chainsaw (3, 4) and the surface is sanded
5-10. The connection of logs along the length should be invisible to the eye and inaccessible to rain moisture, therefore it is carried out only inside the cuts. In this case, at each end of the spliced logs, its own half of the Canadian bowl is cut out: with the help of a chainsaw, notches (5) are made, the surface of which is planed (6) and polished (7), and then on the upper edge of the saddle the contours of the half of the hole for the fat-tail tenon are outlined (8 ) and cut it out (9,10)
11,12. The height of the walls of the log house is slightly more than 3 m, and in order to lay the upper crowns in it, carpenters have to make Canadian bowls on site. Such work, in addition to high qualifications, also requires certain balancing act skills, but this is easier to do than removing an already installed crown at half the height of the wall and mounting the second half of the cage on its basis
13-16. The contours of the longitudinal semicircular groove are outlined using the “line” (13), and then cut with a chainsaw (K). Next, the wood is divided into segments (15), and then removed using an ax - adze (16)
Log cutting technologies - from Canadian logging to Post and Beam houses.
IN wooden house construction There are two main technologies for cutting a log house - this is bowl cutting, it is divided into Canadian and Russian cutting, as well as frame-log technology - the so-called Post and Beam, from English words Post and Beam (post and beam).
Thanks to manual cutting the highest quality is achieved, which cannot be obtained when processing logs using other methods. Precisely when manual processing the log ideally retains its qualities - warmth, durability, natural beauty and resistance to environmental influences. Technology manual cutting influences not only the style and appearance, but also on the thermal conductivity and manufacturability of chopped logs. Possibility to use various materials for home decoration and construction. We will try to explain to you what the differences are.
Cutting a log into a bowl
Cutting a log into a bowl is the most common type of cutting. The walls in this case consist of logs located horizontally. At the junctions or intersections of walls (cuts), bowls are cut out of the log during cutting. The cutting technology can be used according to Russian technology with a round bowl or the Canadian cutting can be used, which is also divided into two types - traditional Canadian or diamond bowl.

Cutting a log into a Russian bowl has long been the most common type of cutting in Russia. In cutting, all logs and bowls are round in shape. Disadvantages of the technology of cutting a log house into a Russian bowl.As the logs dry out, they decrease in size and cracks form at the corner joints of the logs, which become larger the larger the diameter of the log. For example, if you used logs with a diameter of 30 cm in your log house, then gaps of about 7 mm may form, and if the log is 40 cm, then gaps may be up to 10 mm. Advantages of cutting a log house into a Russian bowl.It’s not for nothing that this type of logging has taken root in cold Russia. Typically, the width of the groove in the log (thermal lock) is approximately half the diameter of the log. |
Canadian log cabin
Canadian log cutting is the most logical technology in wooden house construction using logs with a diameter of 36 cm or more.
The main advantage of the Canadian bowl is that when cutting a corner joint on top of the log, notches are made, which give the log at the point of cutting not a round, but a saddle-shaped shape. Thanks to this, the top log during the drying process does not form a gap in the cut, but slides down along the made notches and prevents the appearance of gaps between the logs.

During cutting, the upper edges are formed in the log to improve the shrinkage process. Advantages of the technology of cutting a log house into a Canadian bowl.Shrinkage processes wooden house for residents they pass more unnoticed. Disadvantages of cutting a log house into a Canadian bowl.When forming ridges, thanks to which the drying process in the Canadian bowl is more favorable, the width of the thermal groove between the logs decreases. When cutting a log into a Canadian bowl from a log with a diameter of 30 cm, the width of the groove will be about 10 cm, and from a log with a diameter of 40 cm, about 15 cm. |
Cutting a log into a Canadian diamond bowl
|
A wooden house or bathhouse cut into a diamond Canadian bowl is considered aerobatics. A chic appearance is achieved not only by the upper cuts in the cut, but also by the lower ones. Thanks to the multiple intersections of edges (cuts) in the cut, this type of cutting got its name - diamond cutting. Advantages of the technology of cutting log houses into a diamond Canadian bowl.The same as in the traditional Canadian bowl - favorable processes for felling during the drying period of the log. Disadvantages of cutting a log into a diamond Canadian bowl.Small width of the thermal groove. It may be even narrower than that of a house built into a traditional Canadian bowl, since the log has grooves at the top and bottom of the log. We recommend building diamond Canadian bowl houses from logs with a diameter of at least 46 cm. |
Log cutting in a hybrid style.
|
Advantages of cutting a log house in a hybrid styleIf you have a complex (not gable) roof, then it is not possible to use chopped gables. The rafter system is rigidly fastened with lathing, counter lathing, roofing covering will not allow pediments located perpendicular to each other during the drying process to naturally change the angle of the roof slope using traditional sliding supports for rafters. On the gables between the logs, gaps are necessarily formed equal to the size of the log's sound. Disadvantages of cutting a log house in a hybrid stylenone |
Everything is very simple and clear! The first floor is chopped, Log cutting using Post and Beam technology
|
The technology of cutting a log house Post and Beam, when the frame - the base of the house consists of beams and pillars made of logs, allows the use of a variety of materials to fill the walls - horizontal logs without overcuts, stone, glass. As a rule, frame walls are made with cladding of various types of cladding boards - log siding, shingles, imitation timber or unedged boards. Also on frame wall can be easily installed tiles or wallpaper. Frame log houses allow you to use completely different finishing and building materials in design Advantages of Post and Beam log cuttingThe frame-log structure is very stable and practically does not shrink. Disadvantages of log cutting using Post & Beam technologyA disadvantage of the frame-beam structure may be filling the walls with chopped logs. The height of posts and beams in Post & Beam houses remains unchanged over time, while log walls are subject to shrinkage.

The rich experience and knowledge of the carpenters of the Medvezhiy Log company allow the construction of a wooden log house to be carried out by any in a known way beam house
Wooden houses made from solid logs or beams are distinguished by their durability and environmental friendliness. They keep warm in winter, cool in summer, and natural circulation air, which is also saturated with the healing aromas of wood, allows you to get maximum pleasure from staying in a spacious house.
Today, such wooden masterpieces, after decades, are again becoming popular among Russians, because housing is made from solid log or timber - it is fashionable, practical and beneficial for the health of its inhabitants. But planning to buy wooden frame or order a house from the company " Chopped structures» for a unique project developed specifically for you, it is worth initially familiarizing yourself with some of the features of their production technology, which will subsequently affect the operational characteristics of the housing. It is worth noting that regardless of the methodology used or combination thereof, the house or bathhouse built by the company’s craftsmen is of high quality and evokes a sea of positive emotions in the owners not only during the first acquaintance with the project, but also over many years of living in the house.

Over the course of a couple of years, the process of shrinkage of the wood from which the frame is made takes place. Since, when drying out, the log decreases in diameter by 5-15%, the shape of the bowls and grooves changes, and gaps appear.
After drying, the house shrinks. At this stage, the differences in technology are most noticeable. As a result of shrinkage in the classic version, noticeable gaps remain, which subsequently need to be sealed with tow or jute. And when making a Canadian log house, thanks to the cuts and the triangular wedge-shaped joint, jamming occurs, during which a dense cut is formed at the corners, which is distinguished by its aesthetic appearance and retains heat in the house.
Over time, the Canadian log house was improved, as a result of which a tenon, popularly called a “tail tail,” was added to the hems and trapezoidal shape of the log house. It is designed to prevent the corners from being blown through and to insulate them after the house has dried out and settled.
Canadian logging technology is widely used by the Logged Constructions company during the implementation of projects for the construction of houses and baths, using timber or logs for this. Professional companies produce quality training and the laying of logs, resulting in a cozy, luxurious and warm wooden structure.
Logging technologies originated and developed in different countries almost simultaneously. There were many similarities in them, but there were also differences. The craftsmen studied the experience of their foreign colleagues, adopted the best - this is how Canadian cutting technology appeared, combining the best features of Norwegian and Russian cutting. Many log houses today are built using this technology. Let's get to know her better.
Canadian cutting is done by hand. This labor-intensive process, so you can’t call it cheap. But the owner of the log house receives many benefits that completely cover all the costs.
Distinctive features of the technology
Like other types of logging, Canadian logging has its own character traits. The main feature is a groove of a special shape, with a hidden tenon (tail), a bowl and an outer groove. To ensure a clear match of the elements of each log, it is necessary to cut out the groove very precisely. The master must have not only experience, but also a special set professional tools– a special compass for marking and an electric saw with which to select wood.
Manual felling requires professionalism from the builder, impeccable knowledge of technology and many years of practice. Such masters work in construction company SEC "Russian Izba" How we cut log houses using the Canadian method: a groove with edges is cut in the upper part of the log. A tenon is carefully cut out on the bottom of the log. During the shrinkage of such a structure, the peculiar “locks” self-jam, and the structure turns out to be very strong, without cracks or gaps. Let's take a closer look at all the stages of construction of Canadian log houses.

Sequence of work
The first stage of any construction is the procurement of material. We won’t dwell on it, because our other materials are devoted to harvesting and drying logs. Let's start with the stage of selecting logs and processing them.
Before building a house using Canadian technology, you need to remember that the slightest violation of technology negates all the advantages of such log houses. Therefore, do not take risks by contacting an unverified company. Masters guarantee you high quality at a reasonable price.

Canadian logging allows you to build durable and energy efficient houses and log baths different diameters. Thanks to the internal tenon in the bowl, the lock self-jams, the walls are airtight, and the joints do not come apart in the corners. Such log houses do not need re-caulking! Carpenters from ROYAL CEDAR have been practicing the construction of log houses using Canadian technology since 2002.
The history of the appearance of Canadian logging
In the mid-18th century, Russian settlers brought this technology to Canada. The local population (Indians and Eskimos) did not know this method of building wooden houses.
In Russia at the same time, architects preferred faster and less labor-intensive methods cuttings Arriving in Canada, Russian craftsmen were forced to adapt Russian cutting to local conditions, sacrifice speed and simplicity, giving preference to reliability and thermal efficiency.
Now Canadian log houses are popular not only in North America and Canada, but also in other countries, including Russia.
Advantages
It is profitable to build houses and baths with “ROYAL CEDAR”! Only we:
- We carefully select building materials. We have a production site and logging plots. We don't buy timber, we cut it ourselves in the Siberian taiga! Each tree is inspected by a master with twenty years of experience and checked with an ultrasonic flaw detector. For construction, blanks with good indicators of curvature, density and resin content are used. Our logs have no visible or hidden defects. Unsuitable specimens are rejected and used for lumber production.
- We develop detailed projects. The sketch part is a sectional view of the frame, a layout with an explication of the premises and a foundation plan. All documents necessary for production are contained in the constructive section: cutting maps for all types of lumber, diagrams for laying crowns and wall layouts. All design documents are created automatically, which eliminates errors. Our log houses are cut in strict accordance with design developments, and each item in the estimate can be justified with documentation.
- We hire the best carpenters and finishers. We build turnkey houses and bathhouses. We do not involve subcontractors in our work; we carry out all design, construction and finishing work ourselves. Our staff employs the best Siberian carpenters and all-round finishers, so we are confident in the result. All work is our guarantee!
- We offer prices from the manufacturer. Projects from ROYAL CEDAR contain documents that allow you to save: cutting cards wall material and specifications for all lumber. We are manufacturers and do not work with intermediaries. Our Customers pay only for the material and work of our craftsmen. Remuneration for intermediaries and resellers is not included in the construction budget.
Canadian logging: technology features
- Canadian cabin combines the characteristic features of Russian and Norwegian styles. Large diameter logs are suitable for construction, which are carefully adjusted to each other when assembling the structure.
- Carpenters make a special “lock”: V lower crown a tenon is cut out in a wedge-shaped bowl, and a trapezoid-shaped bowl is cut out in the top one. Under the weight of the logs, during shrinkage, the fastening becomes tightly jammed, thereby achieving complete tightness of the “lock.”
- Full matching of bowls in shape and self-jamming of the “lock” minimize the risk of connections being exposed over time. Atmospheric moisture does not penetrate inside the corner. The insulation located in the grooves retains its natural properties for a long time.
- Using Canadian technology, they make double-sided kneading logs at an angle of 45 degrees. The length of the notch is equal to twice the diameter of the log.
- For Canadian log houses, logs processed with a stapler are used. This tool allows you to very carefully debark the workpiece, leaving the sapwood intact. Such logs look original, and log houses made from them last a long time.
- The grooves are made with an adze, the wood is hewn along the grain. This allows you to clog the pores and resin channels. This “preservation” increases the service life of wood.
- For Canadian logging, it is recommended to use logs with a diameter of 400 mm or more. We build from cedar, pine and larch with a diameter of up to 700 mm.
Features of Canadian logging logs
- Tightness. A log house with round bowls needs caulking or wall treatment after shrinkage acrylic sealant according to technology " Warm seam" The appearance of cracks is associated with a decrease in the linear dimensions of the log due to shrinkage. In the Canadian cabin there is no this problem: the inclined edges of the lock and self-jamming under the weight of the rims and roofing system maintain the tightness of connections. No cracks appear in such a log house, the notch remains sealed.
- The walls look monolithic. There are no gaps between the crowns; this is maintained throughout the entire life of the log house. The insulation remains inside the log, it is not visible and is reliably protected from environmental influences.
- Beautiful appearance. The notches on a large diameter log look original. In the construction of elite log houses, logs with expressive butts are used. The ends are shaped “under a wedge” or “in a run-up pattern”. French and straight end cuts are also available. Our carpenters have an original technique for drawing butt parts. Large-diameter logs processed in the “wild” style or with partial debarking are widely used. The massive chopped trusses that decorate the entrance look original.
Diamond bowl or Diamond edging
- Construction of houses in a diamond bowl requires high skill from carpenters, because this is a very complex technology. The difference from the usual Canadian method is the number of stitches - they are performed not on one side of the crown, but on two:
- A large number of edges intersect in cuttings, which looks like a diamond. This is where the name of this method comes from, with the help of which you can emphasize the natural shape of the butts and the beauty of the wood texture.
- The pinnacle of craftsmanship are considered tightly fitted (up to a millimeter) corner connections crowns
- Benefits of a Diamond Bowl the same as that of an ordinary Canadian one: complete tightness and absence of cracks after shrinkage of the log house.
- The only drawbackdiamond cutting is to reduce the width of the thermal groove. It is for this reason that it is advisable to choose this type of felling when building wooden house from logs with a diameter of more than 460 mm. In large log houses, diamond cutting looks especially elegant!

Construction time
Construction time depends on the complexity of the project, the diameter of the log and the workload of the production site.
