The soil study

Prior to construction, a soil survey is usually carried out to determine the composition and characteristics of the soil at the construction site. This step is important because it ensures that the land is suitable for construction and that the foundations will be solid. In Quebec, soil studies are regulated by the Quebec Construction Code.

Land preparation

This involves setting up the necessary equipment and materials to prepare the land for construction. In Quebec, this step may include the removal of vegetation, the demarcation of the construction perimeter and the installation of site fences.

Extraction

This is the removal of soil and materials that are not needed for construction. This step is important because it sets the stage for the following steps.

Water drainage

This involves setting up the necessary drainage systems to evacuate rain and surface water from the construction site.

Disbursement

This is the removal of the top layer of soil to allow the construction of the foundations.

Excavations and trenches

This involves carrying out the necessary excavations for the construction of foundations and basements.

Servicing

This involves setting up the water, electricity and gas networks necessary for the operation of the building or infrastructure.

Laying a geotextile film

This involves placing a protective layer under the concrete slab to prevent water from seeping into the foundation.
