Lags are made from spruce, treated with antiseptic drugs. Brutus for the lag should be well dried. All this is necessary for a longer service life. For the better strength of the floor, lags are installed at a distance of no more than 40 cm from each other. The thickness of the lag is 30mm. Lags are laid with level measurements, so that the floor does not have waves or bubbles. If a new house is being built, then there are several options for the installation of floors.
