Stone column (for ground improvement)
Franki Geotechnics B
structuring of the basement by incorporation of gravel columns compacted by beating or vibroflotation
Characteristics:
the diameter is determined by the ground, with the means 20à25% larger than the tube of beating
entredistance starting from 2m, maximum 3m.
foundation rafts simpler than to erase on piles
the characteristics of bearing pressure are higher by beating
Scope of application:
foundation of the tanks and storages
economic solution for light constructions on ground compressible
improvement of the stability of a slope
faster consolidation under considerable fill
