Project Description
Where CMCs are adopted on sites with near surface granular or mixed soils, the top of the CMC can be replaced with stone aggregate to produce a composite column, known as a bi-modulus column (BMC).
The BMC optimises the transfer of the building loads into the column and is constructed in two stages: The CMC is formed first to the surface followed by the construction of a stone column at the top.
Benefits:
- Enhanced bearing capacity
A reduction in the total and differential settlements
Easy excavation for foundations
The displacement process creates no spoil
Very high production rates reducing costs
Application:
- Heavily loaded commercial/industrial floor slabs
Road and rail embankments
Silos, tanks and wind turbines
Residential buildings traditional founded on driven piles
