Common foundations and base plate differ from each other

People concepts the foundations of a family house and a foundation slab mistakenly consider one and the same. Before building a family house, the question must be whether the foundation strips loaded with the nose masonry are sufficient or a floating foundation slab is required. In the case of foundation strips, the concrete slab is a non-load-bearing floor, suitable for technical background or garage.

At the base of the family house is enough concrete B / 15

Experts and laymen often mistakenly believe that B15 (C12 / 15) and B20 (C16 / 20) are just enough to be found on the foundations or foundation strips, and on the non-bearing surface and lost formwork. The foundations of a family house created by foundation belts will be the most burdened. Pressures from above, below, under water, and frost. The reason for poor choice of concrete is to save money on the material. The concrete layer and its class should always be specified by the designer.

Errors in Building the Foundations

The deep foundations of a family house need to be cleaned manually and rid of large boulders. It is also necessary to get rid of the groundwater. It is only then that the belts can be poured out with concrete. Lost formwork is necessary to arm the armatures at regular intervals into the foundation strips.  The base belts must be at a non-freezing depth of min. 80 cm.

It is not possible without isolation

The foundations of family houses need to be isolated, for example by using asphalt bands. At the risk of pressure water two layers are used. The insulation is deposited on a flat surface with penetration. Fundamentals can also be insulated with screed material or PVC foil. At the base of the family house, it is better to call a professional company that will also carry out preparatory earthworks and excavation work.
