Design, construction and testing of foundations

The key to the reliability of the concrete floor is a properly designed sub base, which takes into account the results of geological studies and design loads.
Our company offers a reliable way to test the stability of the sub bas, which most accurately characterizes its bearing capacity. The module of deformation is determined with the help of the equipment, empirically and directly on the site using the bearing plate test method according DIN 18134.
Testing of the sub base is performed both for checking the bearing capacity of natural soils in order to use the obtained results to design the concrete slab, and for the verification of compliance of the design data on the finished flooring underlay before concrete flooring.
We have the necessary equipment to perform tests according to DIN 18134.
 There are several versions to prepare a sub base:
1. The traditional one is using sand and gravel.
2. The method of stabilizing the sub base: mixing a 30cm thick top layer of sand with cement.
3. Execution of a lean concrete layer.
4. Strengthening the flooring underlay with geological grids, if the sub base contains relatively unstable soils.
