The Cavity Filling process® consists of filling an underground cavity using deactivated clay balls, then injecting a resin into the filled volume to improve its resistance.
The expansion of the resin allows perfect bonding in the upper part of the cavity. This process is perfectly suited to filling various cavities, whether anthropogenic or natural: tanks, cellars, crawl spaces, underground galleries, etc.
This technique can be carried out in inaccessible places (eg cellars) with very rapid securing of risk areas.
If applicable, Cavity Filling® also makes it possible to fill crawl spaces and therefore to transform a floor over a crawl space into a floor over a level ground!
Immediate efficiency: no drying time during keying
Very fast safety in risk areas
