The type of foundation is chosen depending on the characteristics of the soil. If it is unstable, for example, it is located on swampy soil, or there is a problem of a large depth of soil freezing, then the classic tape shallow foundation is not suitable. For such soils, combined systems such as columnar-strip foundation are used.
Construction of a column-strip foundation
The structure and composition of the strip foundation with the pillars are similar to a regular column foundation. However, unlike the columnar, the supports form a single structure and are connected with a tape.
The column-strip foundation is required for several purposes:
- Connect the supports to each other in the structure, especially if the buildings are built without rigid walls;
- Close the basement of the house with a solid structure – this way you can avoid problems with high humidity and pollution;
- Form a surface for laying wall material.
The column-strip foundation is used in the construction of working and residential buildings, which are being built according to Canadian technology. Such a base is ideal for SIP-panel houses. It is acceptable to build a basement – this is a great opportunity to build a workshop or storage room on the basement floor.
Builders create an air gap between the tape and the soil to compensate for the deformation of the heaving soil. Unscrupulous craftsmen make a big mistake when they fill voids only with sand. They attribute this to the cheapness of sand and the fact that it warms the place under the house. In fact, on a sand cushion, the foundation can be deformed.
It is better to entrust the manufacture of a columnar foundation to professionals. On the Internet, you can find diagrams and work steps to make a non-buried column-strip foundation on the ground with your own hands. But for this you need to have experience in construction and relevant knowledge, otherwise mistakes cannot be avoided.
The construction of the foundation consists of the following stages:
- Levelling the area, getting rid of debris and vegetation.
- Carrying out site markings with ropes which are pulled over pegs.
- Digging a trench, taking into account the thickness of the form work.
- Digging recesses where the support pillars will be located.
- Installation of supporting pillars. The foundation can be made of reinforced concrete pillars, brick or wooden – the choice is up to the client.
After completing these stages, the builders begin to pour the foundation with a concrete mixture. Making a foundation and building a SIP house costs little money compared to other options. By entrusting the work to professionals, especially in the case of building a foundation on bulk soil, you can be sure of the quality of the building.
In private construction, a column-strip foundation with a grillage is often placed. Its cost is even lower, as even less concrete is required for laying the foundation.
