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