Gamarco Construction Inc. approached Menard Canada to improve the soil of the foundations and the slab under the multi-use building at 3500 rue Gaumont in Laval, Quebec. The land area to be improved was 3,307m2, including an overflow of 3m.
The geotechnical data extracted from the drilling reports indicated to us, throughout the site, the following soil profile:
- Heterogeneous fill (silt, sand, gravel, clay, organic matter and blocks) From 2.08 to 3.05m deep.
- Silt and clay deposit from 2.13 to 2.44m (EL = 22.42m to EL = 22.11m) in depth.
- Granular deposit (glacial moraine) From 2.13 to 3.05m (EL = 22.11m to EL = 20.6m) up to 9.37m (EL = 15.10m) depth.
- Loose to compact compactness with an “N” index between 7 and 24.e
