CONTROLLED MODULUS COLUMNS

What it is:
Controlled modulus columns (CMC) are concrete columns placed in a network adapted to loads and settling criteria, combined with a granular bed. This distribution bed spreads the applied load between the ground and the CMC.

How it works:
These columns, made using a discharge auger and injecting concrete through the tool’s hollow core, usually have a diameter ranging from 280 to 420 mm. They increase bearing capacity and reduce settling.

Why it’s used:
Controlled modulus columns are an ideal alternative for pilings and structural slabs, useful for buildings with a conventional or slab-on-grade foundation. The process can be used on all soil types (clay, organic soil, fill) and is equally suitable for high load structures (highway approach fill, storage tanks) and buildings/plants (distribution warehouses/residential buildings/stores).
