Soil mixing involves modifying the properties of weak soils to improve their load carrying and permeability characteristics.
The process involves using a single or multiple tool auger to break up the soil and then inject at low pressure a specifically designed binder, which is then thoroughly mixed with the soil. The mixing can be designed to be done as isolated columns or as a mass treatment.
Benefits:
- Enhanced bearing capacity
Reduction in settlements
Reduced liquefaction
Reduced thrust behind retaining structures
Increased reaction around piled foundations
Reduce permeability, blocking water movement and containing contamination
Application:
- Foundations of low-rise buildings and houses
Commercial/industrial hardstanding, foundations and floor slabs with high tolerances
Infrastructure schemes including embankments, water treatment plants and windfarms
Contaminated and landfill sites
