Wooden Houses. FAQ .

Tree – one of the most ancient and traditional building materials, combining both sufficient strength, various textures, aesthetics, excellent thermal insulation and environmental cleanliness. By the same author: Leanne Marchevsky. Wooden house suitable for all climatic conditions, so the construction of wooden buildings can be built on the territory of Russia. What are advantages of wooden walls? Wooden walls have low thermal conductivity, so if the house was not heated in winter, warm it up to comfortable conditions possible for several hours. Wood recreates the healthy microclimate in the house, excess moisture quickly leaves the room. The walls are made of wood light-resistant.

They can be to build a pier foundation or foundation "floating bars". Wooden walls can withstand an unlimited number of cycles of freezing – thawing, but because their lifetime can exceed 100 years. Which wood best suited for building homes? Most comfortable for the sanitary-hygienic requirements (including those due to its low thermal conductivity) are bruschatye and log walls of coniferous trees. Conifers the breed is more suitable because they have more regular form the trunk and less susceptible to decay than the deciduous. Which wood needed for building log walls? This forest is necessary to "bring down" in winter, when wood will be dry and easy to handle. Calculate the minimum diameter of the logs on the basis of the relationship: for each degree of possible frost in winter – 0,8 cm diameter logs or timber thickness. Thus, north of Moscow logs should be 20-25 cm in diameter They definitely need oshkurit, or under the bark will collect a variety of parasites.


Asphalt works – a process unit of pavement. Modern technologies allow asphalt to do better road surface than a few years ago. Now the company who orders roads Petersburg can even choose the color of asphalt pavement! The process of asphalt used everywhere. It is used in road construction, and patching of roads, and beautification Territories – asphalt playgrounds, parking lots, etc. Technology asphalt.

Asphalting is done by laying asphalt mixtures prepared base. The first stage clearance territory under the asphalting. Next on the cleared ground is laid foundation for future road or area. Thus the base can serve as a nonrigid foundation – otsevnye materials (crushed stone, gravel) and hard foundation – concrete. On the resulting base is laid asphalt concrete mix.

Asphalt concrete mix produced at manufacturing plants, or on site – from a strictly defined proportions of sand, gravel, mineral powder and bitumen. Then this mixture at 175 C delivered to the facility, where it is laying. As a rule, asphalting done in one or two layers. If you anticipate an increased load on the road, then placed 3-4 layers of asphalt mixtures. Laying blacktop carries asfaltobetonoukladchik. The last stage of compaction layers of asphalt produced rollers. Further, the surface is treated with bituminous asphalt emulsion. Asphalt mixture. Asphalt mixture is separated into crushed stone, gravel and sand. Further classification of mixtures is a function of temperature packing. According to this criterion asphalt mixture can be divided into hot and cold. Hot mix laid at not less than 120 C, cold – at or below 5 C. Hot asphalt can be divided into coarse, fine and sandy, depending on the the largest size of mineral grains. Cool the mixture can be divided into fine-grained and sandy. Depending on the porosity of asphalt concrete shall have the following split: – hot asphalt concrete: high-density, compact, porous, highly porous – cold asphalt have a residual porosity of 6% to 10% (GOST 9128-97). Further, gravel and gravel are divided into types: A, B, C, D and D. For more types of decoding gravel and gravel concretes can be found in gost 9128-97. Asphalting should be done in the dry warm weather. Work on the device cover must be completed 15 days before the autumn rains. The exception is the mixture with activated mineral materials. It should also be keep in mind that when installing a stacked layer asfaltobetonoukladchikom thickness must be greater than 15% than the design thickness. Asphalting of the road to hold area go to the technology under the force not to each company. Only qualified technicians can carry out road construction Petersburg, and these roads will last a long time.
