There are warm and cold underground.

— cold underground located in unheated homes. Here, the internal temperature is equal to the outdoor. Ventilation is carried out at the expense of the vents placed in the foundation. Air exchange with air inside the house is not made.
— warm underground set for heated frame buildings. the underground temperature is approaching the temperature inside the house, as are underground vents in the floor of the ground floor rooms. Foundation in these homes insulated. The average depth of the underground from 15 to 25 cm. At smaller depth deteriorating ventilation and heat loss increases as much.

Excavation

- At the first stage of building the underground topsoil is removed.
- Further deepening is about 20-30 centimeters below the planned depth.
- indentations must be compacted.

- In wet soils done using a roofing waterproofing or polyethylene. Can be used as a waterproofing liquid clay. This clay pit spread and tamped.
- Then a layer of sand is filled at least 5 centimeters. On sand gravel is filled from 10 to 15 cm. Each layer is compacted.
- After the completion of all preparatory earthworks mounted floor.

Ventilation warm underground

For the purpose of the underground ventilation in the corners of the room in the floor are made holes, which are closed with decorative grilles. Holes - not less than 100x100 mm. These vents undesirably close furniture, laminated or coated, so as not to block the air circulation.

It is possible to provide ventilation through a special mounting plinths. They beat with a small gap above the floor of 1 to 2 mm. Such a gap on the perimeter to ensure a good air circulation.

The following method - vent windows in the plinth. On the reverse side of the plinth slotted groove depth of 1 millimeter, a width of 5-6 mm on the whole length of the floor. This groove is made small windows up to 5 centimeters. Just enough to make the window 2 on opposite sides of the room to provide adequate ventilation in the underground up to 25 square meters. Cover windows with decorative grilles. It is best to place them under the batteries, which due to the heat generated by the active air circulation.

Ventilation cold underground

Such underground ventilation due vents placed in the foundation. They are placed at a distance of 2-3 m., Close up decorative lattice. In winter, the vents are closed partially. If the vent can not cope, and underground water appeared, apply additional ventilation: temporary - on vents fortochnye installed fans or permanent - on the ventilation pipes are installed leeward of the carcass houses. This will increase traction.
