What is the purpose of a foundation

Foundation types and their areas of application

If you want to build a single-family house, a holiday cottage or just a kit garden house or a carport - the practical implementation always begins with a foundation. It has to be frost-proof and has to fulfill the task of bearing the weight of the structure. That is why it must be designed in terms of its stability in such a way that it cannot tear. The foundation should not be oversized either, because it is associated with material costs and wages. If you set up the foundation yourself, you will have to add your own investment of time and muscle power.
The bottom line is therefore to make every foundation safe and stable, but as efficient as possible. Therefore, at the beginning of the foundation planning, there is the question of what type of foundation is required.

The point foundation

Carports consist of vertical supports and a roof. The weight of the construction therefore only rests on these supports. It is therefore sufficient to set up a point foundation approx. 40x40cm and frost-proof to a depth of 80cm on each of these supports. Making foundation strips between these point foundations would be wasted material.

Point foundation with base plate

This variant relates e.g. B. on a kit garden shed. Its load-bearing structure consists of square timbers that have to stand on point foundations. However, it is advisable to concrete the entire floor about 10cm high and with a steel mesh reinforcement so that it is crack-proof. The floor of the garden house is held securely on this base plate.

Strip foundation

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

Strip foundation with base plate

This is the most common form in house construction, where the strip foundations are continuously exposed to masonry. In order to create a homogeneous unit, it is concreted together with a base plate up to 20 cm thick with steel reinforcement.

White tub

It is the most expensive tub of a foundation and is used in basement construction in building areas with high levels of water exposure. It consists of strip foundations below the basement floor and a reinforced concrete floor slab cast on site. The cellar walls are poured onto it in the reinforced concrete formwork and special seals are incorporated at the connection points. Only specialist companies are qualified to carry out this work.
