The high-capacity foundation
We produce foundation elements at great depths.
Using diaphragm wall methods, we excavate rectangular, cross-shaped or H-shaped barrettes elements.
The stability of the trench during drilling, reinforcement and concreting operations is achieved using a perforating fluid called slurry. The slurry is made from bentonite. It forms a watertight deposit called a “cake” on the walls of the excavation, preventing it from percolating into the ground and providing the hydrostatic pressure that prevents the walls from collapsing. A slurry made from polymers can also be used.
Barrettes have a similar function to foundation piles, but thanks to their geometry, they can take much greater loads.
This is the solution for founding towers, large buildings and major infrastructures.
