Laying   Base layer    
The base layer, laid on top of the subfloor, on which the paving is laid is to be created. The most commonly used system for laying of cubes consists of a dry mixture of sand and cement type R 325 (200kg/ m3). Depending on the element used for the paving and its thickness, a suitable thickness of the base layer must be built. The laying on gravel is particularly suitable for the sealing with Elastofuga®. The laying of flags, crazy paving, kerbs, delimitations are carried out on a mixture of concrete layer.
