Our expertise

Drilling and Geotechnical Studies

Drilling and geotechnical studies aim to identify subsurface conditions of a site using a minimal number of boreholes.

Geotechnical Drilling

Geotechnical drilling conducted by our qualified technicians aims to identify potential soil contaminations and the extent of contamination, as well as to precede residential, commercial, or industrial development projects.

Various types of geotechnical drilling include:

Manual drilling: in confined spaces and within buildings
Manual drilling: horizontally under foundations
Environmental drilling: Geoprobe® 420M, 6610DT, and 7822DT rigs
Installation of piezometers: groundwater sampling
Rock drilling – up to 15 meters deep
Geotechnical drilling: assessing soil conditions

Geotechnical Studies

Geotechnical studies provide essential information for decision-making in various types of renovation, maintenance, or development projects:

Foundation soil inspection: This expertise is conducted before the construction of new structures to confirm the bearing capacity used for structural design.

Slope stability evaluation: Assessing the safe setback margin for structure construction or stabilization measures.

Frost protection details: When adequate ground cover for frost protection is insufficient, frost protection can be supplemented by laying extruded polystyrene insulation (i.e., Styrofoam), the thickness of which varies depending on the thickness of the existing ground cover.

Estimated percolation time and silt content for septic tank design: The estimated percolation time is used for septic system design based on grain size analysis (correlations between grain size and permeability).

Noise assessment study: In residential and commercial developments near railways or major roads, it may be important to assess the noise impact on receivers. When noise levels exceed acceptable noise levels, mitigation measures such as barriers and specific building materials can be suggested.

A word
of our customers

"When faced with a contamination issue, they guided us through resolving the numerous challenges that emerged. Dealing with this kind of unpleasant surprise exposes property owners to a plethora of proven or potential problems. From the outset, Spheratest provided us with the best advice for carrying out decontamination according to industry standards. The company has always demonstrated diligence regarding deadlines. The staff is always courteous, punctual, and available. Everyone I encountered was highly knowledgeable in their field. Furthermore, Spheratest has always been transparent about costs, a major factor in such a stressful ordeal. They are a group of people for whom quality seems to be a cardinal value. Moreover, they treat you as a human being. In such a trial, this is invaluable. It is a top-notch company that I highly recommend."

"I wanted to highlight the excellent work of your project manager. It's truly pleasant to work with her. She is reliable, follows up diligently, and summarizes the issues very well. Our calls last an average of 3 minutes; she doesn't waste my time, and I have all the information I need. It's perfect."

"Thank you very much, I have always felt that you are very professional people. I can tell you that we feel confident with you and see such a difference. Thank you for being on our path to help us navigate through a situation for which we would have otherwise passed, believe me."

"On my site, I expected phases 1 and 2 to be a necessary step, and that we wouldn't discover anything more than what I already knew. But that was not the case. The Spheratest team accompanied me throughout the soil decontamination and rehabilitation process, which was long and full of challenges. Fortunately, they were patient in answering my 1001 questions in the face of my total lack of understanding of what we were finding with every shovel of dirt. They were diligent, available, present, understanding, and flexible to adapt to everything my site required. I greatly appreciated working with the Spheratest team, particularly Isabelle and Benoit, with whom I had many exchanges."
