When choosing a foundation, you should alsoto focus on what kind of building will be built. For small, light buildings it is worth choosing a belt or pile foundation. If you plan to build a spacious mansion in two or three floors, it is better to pour a monolithic slab. Such a foundation is ideal for construction on shallow soils.

In any case, whatever type of foundation you havePreferably, it is worth paying close attention to the choice of materials. It is also necessary to strictly comply with the construction technology, because when its violation, the foundation can quickly collapse. This often becomes the cause of the skewing of the structure, the bearing walls of the building and the roof at the same time experience an unplanned load and are destroyed.

Tape foundation is most common inconstruction. For a small building that is planned to be erected on dry, non-heaped soils, this is an ideal option. There are two types of this foundation - prefabricated and monolithic. Most often make a monolithic ribbon foundation. It is quite economical and does not require special labor, especially when compared with the construction of a solid plate.

Manufacture of a monolithic ribbon foundationincludes several stages. First you need to excavate a trench on the site. Reduce labor costs and increase the speed of construction will allow the use of special equipment. At the bottom of the trench is poured a small sand cushion. Then it should be carefully spilled with water to compact the sand. At the next stage, the reinforcement is laid and the formwork is put out. In this case, the reinforcement must not touch the walls of the form and the bottom, therefore it is recommended to lay iron bars on broken brick. You can use welding to fasten the reinforcement, but it is best to make a bundle of construction with a knitting wire. After this, it is necessary to prepare a concrete mortar and pour it into the formwork. Select at least ten days for the foundation to dry. Water the concrete tape with water - this will prevent the appearance of cracks.

The column foundation is used for erectionbuildings on weak grounds. It is a construction that consists of separate pillars that are installed at a certain depth. Posts should be placed on the intersection of the bearing walls, as well as in the corners of the building. Posts can be built independently. Also they are on sale, therefore in shops it is possible to get ready.

The pile screw foundation is designed forconstruction of objects on difficult soils, for example, in swampy terrain. Piles can be used again after dismantling the building. This allows you to reduce costs when moving a company from one place to another.

Monolithic slab is most often made on problematicsoils. The foundation is particularly stable, which allows to avoid the skewing of the building on the heaving ground. Also, this type of foundation is used on dry grounds when it is necessary to build a large building. Monolithic slab is the most expensive type of foundation. But in some cases it is simply impossible to do without its erection.
