Selected Technique:
Dynamic Compaction

Treatment Area:
13086 m²

Pépin Fortin approached Menard Canada to improve the soils of the foundations of the future maple syrup warehouse located on Avenue Alphonse Poulin in the industrial park of Plessisville, Quebec.

Ground Conditions

The geotechnical data extracted from the drilling reports indicated that throughout the site, the following soil profile was found:

  • Plant cover over 0.2m
  • Gray sand over a thickness of 0.8m
  • A layer of Silt to a depth between 2.44m and 3.66m
  • A gray sand of medium compactness down to depths between 4.88m and 7m
  • The Till was followed behind by rock

Menard Canada Solution

The performance criteria were to achieve a bearing capacity of 125 kPa for the foundations and 50 kPa for the slab and to eliminate the potential for liquefaction of the soils. Menard Canada carried out the Dynamic Compaction consisting of excavating the soil in line with the foundations and according to a grid under the paving, replacing it with MG112 sand and then dynamically compacting the entire area. This technique is advantageous because it limits the volume of excavation to be removed and hauled away. The CPT-type control drillings made it possible to validate the achievement of the design criteria.
