Types of foundations and their fields of application

If you want to build a family house, a cottage or just a kit garden house or carport - in any case, the practical implementation starts with a foundation. It has to be frost-proof and has the task of carrying the weight of the structure. Therefore it must be carried out in its stability so that it can not break. But the foundation should not be oversized, because it is associated with material costs and wages. Build the foundation in self-performance, plus their own time and muscle power.
Conclusion is therefore to make any foundation safe and stable, but as efficient as possible. Therefore, at the beginning of foundation planning, the question is what type of foundation is required.

The point foundation

Carports consist of vertical columns and a roof. Therefore, the weight of the construction rests only on these supports. Therefore, it is sufficient to create a point foundation about 40x40cm and frostproof to 80cm depth on each of these columns. Creating foundation strips between these point foundations would be wasted material.

Point foundation with base plate

This variant relates z. B. on a kit garden shed. Its supporting structure consists of square timbers, which must stand on point foundations. However, it is advisable to cast the entire floor about 10cm high and with a steel grid reinforcement crack resistant. On this floor plate, the floor of the garden shed finds a secure hold.

strip foundation

A strip foundation takes z. B. on a property partition wall. It must also be frost-proofed at a depth of 80cm and be as wide as the masonry wall.

Strip foundation with base plate

This is the most common form in house building, where the strip foundations are constantly burdened by masonry. In order to create a homogenous unit, it is concreted together with a 20cm thick base plate with steel reinforcement.

White tub

It is the most expensive sink of a foundation and is used in cellar construction in construction areas with high water load. It consists of strip foundations below the basement sole and a cast-in-place reinforced concrete base plate. The cellar walls in the reinforced concrete formwork are cast on it and special seals are incorporated at the joints. For the execution of this work only special companies are qualified.
