Strip Foundation

The main area of strip foundation are buildings with heavy walls (brick, concrete, stone), and heavy floor slabs. Strip foundation is located on the perimeter exterior walls, and placed under the supporting inner walls of buildings or other areas with increased load. Also strip foundation is well-suited for homes, which is planned to create basement, garage or basement. Strip foundation is also suitable in the case of a possible slight deformation of the base. Typically, strip footing located below the level of soil freezing at 20 cm of sandy soil You can lay the strip foundation and higher levels of freezing, but not more than 60 cm from ground level.

For deep-freezing and highly swelling soils usually strip foundation shall not apply. Process itself strip foundation construction is simple, on the other hand it requires a fairly high cost of materials and work on the construction of the foundation. There are criteria for the minimum thickness of the foundation, which can be used building a house. Thus, the minimum thickness of reinforced concrete strip foundation – 10 cm of concrete – 25 cm, rubble concrete foundation – 35 cm, well and laying of natural stone – 50 cm in the construction of strip foundation to be also take into account the permissible load on the soil under the foundation. For clay soils at a depth of 80 cm load should not exceed 2 kg/cm2. In addition to pouring the foundation concrete mixtures, often strip foundations erected using ready-made foundation blocks or bricks.

This speeds up the process of building a foundation. It should also be noted that during the construction of strip foundation is an opportunity to save money raising the foundation to the full depth only during the construction of heavy structures. There is still the most reliable option strip foundation remains solid foundation, more time-consuming and requires prior creating formwork and reinforcement training design to increase strength strip foundation. And in this case, the valves must be connected to each other by welding.
