The base can be:
- crushed stone, gravel
- soil without organic components

It is important that the base is of equal density,
in order not to affect static and hydro isolation.

In certain cases there is a possibility of creating a system
without basic concrete – with geo-felt as basis for hydro isolation foil

Depending on the project solution, we carry out the hydroizolation in different manners, mainly:

-using KONDOR (classic hydroizolation) and

-using hydroizolation HDPE, PVC and PE foils and membranes of different thickness

The composition and layers of hydroizolation are determined on the basis of geological and geomechanical parameters, which is defined in the project

The guarantee deadline depends on the technical solution and hydroizolation.
