We intervine in any case of accidental gas polution, or to prevent any risk of explosion

In cases of odor, subterraneous migration, we can act mechanically: draining channels, waterproofing (membrane, bentonite), de-pressurization, extraction probes.

We do dynamic draining works in construction sites before edification, to protect them against explosion risks We are also called on to intervene in already existing constructions, in the case of gas problems.

We install watching preventive equipments and continuous control. We do extraction works, by dilution, by combustion.
