Rigid inclusions are an economical and efficient ground improvement technique which bridge the gap between vibro stone columns and traditional piling.
Using a displacement auger to displace soil and form concrete columns in order to reduce settlement and increase bearing capacity, rigid inclusions are suitable for weak, compressible soils and are ideal for warehouses, industrial and commercial sheds, embankment support and in some cases residential properties.
Installed using an auger displacement tool to ensure there is limited or no spoil generated, the columns are typically up to 350mm in diameter, are made of a low strength concrete and are unreinforced.
This ground improvement solution works alongside a load distribution mattress which allows for a traditional sub-structure design such as pad foundations, strip footings and ground bearing floor slabs.
