Geotechnical services

Before getting started on any infrastructure project, the soil must undergo a geotechnical survey. The results of this survey will provide essential information for identifying the nature of the soil and for gauging its behavioral characteristics. The geotechnical survey’s depth is decided in relation to the scope of the planned operations.

The barge fleet employed by André Roy Drilling is completely approved by Transport Canada and the Quebec Ministry of Transport. Powerful and secure, these barges were custom built in our mechanical workshops, keeping the specific requirements of this type of drilling in mind. Made from aluminium and able to be taken apart to pieces, some of our barges can be transported by helicopter to remote sites that would otherwise be inaccessible by land.

Forage André Roy Drilling’s exclusive equipment is highly valued by our clients, like the Société d'Énergie de la Baie-James (SEBJ) and Hydro-Québec, who benefit from it to carry out geotechnical surveys in preparation for the construction of new dams, dikes and hydroelectric power stations.

Our barge fleet is also an essential tool in surveying the soil for the construction of deep water docks, bridge pillars over waterways, marinas, water intakes, dry docks, gas pipelines. or any other project that requires drilling on a body of water.
