Strip footing

Tape foundation is usually built in two ways. In the first case (the foundation of small burial) bucket dredge, or hand-digging trenches in the soil. Then, on the side walls of the trenches is laid roofing felt (or other waterproofing material). After that, the bottom of the trench backfilled sand and gravel, and then the trench is filled with concrete. In this embodiment, a small amount of soil from the underground part, provided for the engineering equipment is removed by hand. The second method of manufacturing strip foundation is more familiar. When the housing estate and a basement, first dig a trench, then made the necessary configuration of formwork, which is poured concrete. Under the foundation is dumping sand and gravel. Foundation serves at least 30 cm above the ground. You must perform a quality exterior waterproofing and interior vapor barrier (in the case of a heated basement). Aboveground part and underground part of the upper layer can be executed masonry brick, stone or concrete blocks. Outside, the foundation must be carefully insulated. Application of strip foundation is expedient if the house basement (foundation depth of occurrence). Dignity. Can be made without heavy construction equipment (shallow foundations). Disadvantages. Strip foundations deep bedding more expensive. It requires sealing, insulation, increased attention to the elimination of cold bridges. Requires protection from radon. Observations. To improve the thermal insulation tape around the perimeter of the foundation of Green Buildings home runs horizontal insulation. Sometimes, the foundation makes void, and voids filled with insulation.
