Advantages, purpose and technology of laying grooves
For the manufacture of cobblestones, a stone, clinker, brick and wooden checkers are used. Typically, such floors are found in warehouses, garages and similar household and utility rooms. The floors of slabs are not particularly durable, but they have a low cost, so they are also used in the construction of wooden prefabricated houses. As a rule, paved floors of this type are made of tile wood materials, hard wood-fibrous plates, plywood and boots made of wood particles, combined plates are also used. All these materials must be treated with fire resistant and antiseptic compositions. Some plates have a toxic glue in their composition, so to protect against its evaporation, the elements of the floors have to be treated in advance with varnish, paint or impregnating.
Before installing the floors itself, a waterproof coating of polyethylene film or roofing material is laid on the ceiling, insulation from expanded clay, slag, perlite or dry sand with a thickness of up to 5 cm is poured over it. Wooden bars are shed in isolation, which should be located strictly horizontally. A layer of bulk material about 10 mm remains under the lower surface of the bars. Sheets of sound -absorbing material (soft chipboard, foam of cork plates) are often attached to bars. Finally, profiled tile elements are laid on top, which are nailed to the bars and connected to each other in the bends. A 10 mm gap, which is then closed with skirting boards and fillets, should remain between the plates and the wall. This method of building grooves is used for any tile wood materials.
