Notre expertise


The components are spread mechanically using a truck or manually using a lance and shovel depending on the surface to be treated and the accessibility of the site. If the 1st layer of gravel is always composed of a crushed gray gravel of grain size 6/10, it is possible to have in finish (2nd layer) a crushed gravel of grain size 4/6 of color (stone or yellow tone) which will constitute the final color of the coating.

Concrete deactivated

Deactivated concrete or washed concrete is a concrete with a gravel appearance that reveals rolled or crushed gravels of colors on the surface. Deactivated concrete is conceived in the same way as ordinary concrete. It is enough to dose the different constituents according to the type of concrete that one wishes to obtain and to spoil them. Then it is a question of spraying a setting retardant deactivator at the time of pouring. After a certain delay (from 12 to 48 hours), remove the layer of surface mortar present on the surface of the concrete still fresh with a high-pressure cleaner which will reveal the colored aggregates. The pedestrian use time is 24 to 48 hours and the drying time is approximately 3 weeks.

The Tar

It generally constitutes the upper layer of roadways (wearing course). Asphalt is manufactured in factories called "asphalt plants". It is implemented hot (around 150 ° C). The "setting" effect appears upon cooling (<90 ° C), so it is necessary to compact the bituminous concrete before cooling by subjecting it to the repeated passage of "compacting rollers". Unlike cement concrete, it can be used almost immediately after its implementation.
