Features of construction of foundations

When laying the foundations of any type should do the following: In most designs use concrete foundation. Concrete has the property of gestation, 28 - 30 days. After laying the concrete structure it must withstand during this time without the stress and it is desirable to close or roofing material or other scrap materials from drying the upper layer. During the setting of concrete periodically pour the foundation with water to prevent it from uneven drying. So build a house on the newly erected the foundation is fraught with peril, defects will not keep waiting. Basement waterproofing is essential. She is hot bitumen coating the entire surface is in contact with the ground. Insulate well and walls. To this end, paving the two layers of roofing material (1 st layer - between the base and zero 2-nd layer - between the cap and the main wall of the house). This prevents the walls of the house and basement moisture. Protect the outside of the cap from atmospheric effects. This is achieved by plastering or tiling. For the jointing of the foundation of a rubber-containing mixture was added component (the ashes of burned-out automobile tires). It turns out "coat" for the cap. She is beautiful and secure. When the construction of the cap provides for vent holes. In the summer they serve to ventilate the cellar, and in winter they are shut down, so that moisture from getting into the house. Blind area is needed to protect the foundation from exposure to surface waters. Width of blind area from 0.75 to 1 meter with the slope of the wall of the cap. As the materials used: concrete, asphalt, concrete or well-rammed clay. The device drain rainwater from the roofs also affects the strength of the foundation. Rainwater from the roof falls on the blind area, divides it and cap gradually, evenly moistens the soil near the foundation. This affects the bearing capacity of foundation and contributes to the foundation subsidence.
