Our techniques: vibrodriving, drilling, driving, drains

Our techniques

We adapt to the geotechnical context of each project to offer you the best solutions

Driving

Driving is required when it is necessary to anchor the piles or profiles in a compact terrain, or on a great depth. We use hydraulic hammers on mounted masts or conventional lifting with an independent guide.

Vibrodriving and jacking

Vibrodriving and jacking allow to position and drive piles or profiles in loose soils (clay or sandy alluvium). These processes are efficient, fast and relatively silent.

Bored piles

Bored piles are generally used for the foundation of buildings or structures in areas with loose soils on the surface, and can also be incorporated into jointed or secant pile supports, or berliner walls.

Vertical drains

Prefabricated drains are used to accelerate the settling of fine compressible soils under load. They are installed vertically by static jacking or vibro-drilling, according to a regular grid depending on the nature of the soil.

Ground compaction

Loose granular soils at risk of settlement (under the effect of a load or liquefaction under earthquake) can be densified by dynamic compaction (impacting or free-fall mass) or by vibrocompaction of a profile.
