Project Description

Reinforcement

Dynamic Replacement

Dynamic replacement is an adaptation of the dynamic compaction process for organic, saturated or weak cohesive soils.

The operational process is similar to that of dynamic compaction, involving dropping a heavy weight, but in this instance, coarse stone aggregate is introduced at the surface. This coarse aggregate is punched into the soils to create large diameter pillars of stone typically up to 2m in diameter.

Dynamic Replacement

Benefits:

  • Enhanced bearing capacity
  • A reduction in the total and differential settlements

  • An increase in the permeability allows acceleration of anticipated settlements

  • Ground bearing foundation solutions can be adopted reducing the need for reinforced foundations

  • The displacement process creates no spoil

Application:

  • Commercial/industrial foundations and floor slabs with high tolerances
  • Infrastructure schemes including embankments, water treatment plants and windfarms
