Ground Improvement

Ground improvement is the process of modifying the physical, chemical, and mechanical properties of soil to create a more stable foundation for construction. This can be done through a variety of methods.

Consolidation methods

  • Vacuum Consolidation Method (VCM)

Vacuum Consolidation Method (VCM) is for soft ground improvement, using atmospheric pressure as a temporary surcharge for Soil Consolidation.

Reinforcement methods

  • Deep Cement Mixing (DCM)

Suitable to improve in-situ soft soil strength, like clays, peats, and other weak soils, by mechanically mixing them with cementitious binder.

  • Jet Grout Column

One of the semi-rigid inclusion method, high-velocity water-cement paste is injected through the horizontal nozzle(s) of the rod, which breaks down the soil matrix. The jet erodes and mixes the in-situ soil with grout and upward rotates to form a mixture of soil-cement composite.

Densification methods

  • Dynamic Replacement (DR)

is an extension of Dynamic Compaction (DC) by replace cohesionless soils, after compacting, with large granular column.

  • Dynamic compaction (DC) 

is a ground improvement technique that densifies soils by repeated surface tamping using a heavy steel drop weight.

  • Vibro-replacement (Stone/ Sand Column)

An extension of Vibro Compaction by replace cohesionless soils, after compacting, with large granular column. 

  • Vibro Compaction

A method to stabilize or compact the deep layers of non-cohesive soils, suitable to compact loose, granular soils to mitigate liquefaction and reduce settlement, extremely effective in free draining granular soils.

  • High Vacuum Densification Method (HVDM)

is an advanced method for improving the physical properties of materials. It involves the application of high vacuum pressure to a material in order to decrease its porosity and increase its density.
