This problem is also solved with the help of modern technology. For example, gradually spread to Russia screw bases and in Specifically, the German company krinner developed technology that allows to do all the work for just one day. With a special electric drill foundation, like the screws are screwed into the ground. Next, stand design is inserted into the cavity of the foundation, align at right angles and fixed with bolts and gravel. Perform this work at any time of year and weather conditions. Concrete walls help is widely used in the construction of the walls of the modern home. But it is not usual, and the so-called easy: aerated concrete, foam, polystyrene. Features such materials – low density and high porosity, which reaches up to 80%.

To obtain these figures pores of a chemical way (solution swells with gas additives like yeast) or physical-mechanical (the solution was stirred with foam). This not only reduces the mass of material, but also increases its heat-shielding properties, reduced construction costs. According to Gregory of , a professor of construction materials mssu, the use of lightweight concrete can reduce construction costs by 10-20%, labor costs – by 25-30% 1. The modification also affected the traditional material such as a tree: in our country is built more houses from glued profiled beam. For its production logs sawn into boards (slats) that in the drying cameras are brought to a relative humidity of 6-10% and then processed retardants and preservatives. After that slats are glued together by the overlap of 3-6 units per block.
