Rigid Inclusions (RI)
What are rigid inclusions?
Rigid inclusions are a ground improvement method whereby modulus columns are installed through compressible soils to increase bearing capacity of the ground and control settlements in conjunction with a load transfer platform. The efficiency of the method depends on a number of factors, but the method is often used as an alternative to piling for a wide range of structures, including warehouses and distribution sheds, due to its rapid installation and reduced material costs. As a specialist ground improvement contractor, Aarsleff can install a bespoke solution to meet your project’s needs either solely with rigid inclusions or in combination with driven and CFA piles.
How are rigid inclusions installed?
Rigid inclusions are typically installed using a displacement auger . The rig bores down to the design depth, pushing the ground laterally with minimal spoil generated. The auger is then removed, with concrete pumped through the stem as it goes to support the bore. Zone tests are undertaken on the ground to verify performance.
Advantages:
- Can be used in weak soils to improve the bearing capacity for a wide range of loads
- Applicable across a wide range of sectors and projects
- Can be faster and cheaper than piled alternatives due to lower strength concrete and absence of reinforcement
- Carbon reduction vs traditional piled solutions can be achieved using high replacement lower strength concretes
Rigid inclusions are a versatile solution, perfect for many needs across different sectors. As a rigid inclusions contractor, we are committed to delivering operational excellence in ground engineering, which means we are laser focused on creating value within your scheme.
