Rigid inclusions are a cost-effective ground improvement solution that increases bearing capacity and reduces settlement in weak or compressible soils, bridging the gap between vibro stone columns and traditional piling.
Constructed using a displacement auger, concrete columns are formed with minimal or no spoil generation. Columns are typically unreinforced, formed from low-strength concrete, and are commonly up to 350mm in diameter.
The system is used in conjunction with a load distribution mattress, enabling the use of conventional shallow foundation solutions such as pad foundations, strip footings, and ground-bearing slabs.
Rigid inclusions are well suited to industrial, commercial, and infrastructure applications, including warehouses, embankments, and, in some cases, residential developments.
