Selected Technique:
Controlled Modulus Columns


Treatment Area:
~6,000m²


Project Depth:
6m


The development consisted of a multi-unit 1-storey warehouse approximately 6,630m2 with 10 loading docks in Vars, Ontario. The warehouse was designed for a 20 kPa slab load.

Ground Conditions

The soils at site consisted of topsoil overlaid by silt to sandy silt overlaid by silty clay and/or glacial till. The boreholes hit auger refusal at depths ranging from 5.6 to 7.6mBGS. A grade raise between 1m and 1.9m to achieve FFE was required. Due to the compressible silty clays, the soil was unsuitable to support the foundations and the required grade raise.

Menard Canada Solution

Menard Canada proposed to reinforce the poor soils and provide bearing capacity / settlement control by implementing our Controlled Modulus Column (CMC) system. The CMCs increased the in-situ bearing capacity of the soil up to 170 kPa SLS allowing for shallow foundations. The grade raise and slab loads were also supported by the CMC system.
The solution eliminated the need for deep foundations and a structural slab saving the overall project time and money.
