03 — Our expertise
Quality control and geotechnics
Our geotechnics and quality control services in Quebec cover soil studies, bearing capacity, materials quality control and site inspection, with a laboratory and certified technicians.
Soil conditions and material quality have a direct impact on a project's stability, safety and durability. Construction & Expertise PG provides quality control and geotechnical services across Quebec and Labrador to verify material compliance, assess soil characteristics and reduce risk before and during construction.
Our engineers and technologists carry out soil studies, bearing capacity analyses as well as inspections and sampling directly on site. We also perform specialized testing on cement concrete, refractory concrete, aggregates and asphalt mixes.
Depending on project needs, our team can run compaction tests, grain-size analyses, concrete coring, pyrite analyses and soil aggressiveness testing. We can also determine the corrosion potential of materials and perform non-destructive testing to assess the condition of an infrastructure without damaging it unnecessarily.
Results are analyzed and presented in clear documentation so professionals, contractors and owners can make informed decisions. Whether for new construction, a foundation, a pavement, municipal infrastructure or an industrial facility, PG rigorously monitors the compliance of the work and the materials used.

Frequently asked questions
When is a soil study required?+
Before any new build, extension or underpinning. The soil study determines bearing capacity, stratigraphy and risks — water table, compressible soils — that dictate the foundation type.
Which concrete tests do you run on site?+
Slump, air content, temperature, cylinder casting and concrete core drilling for compressive strength, in line with CSA standards and the project specifications.
How does pyrite testing work?+
We sample the granular fill under the slab, measure swelling potential and issue an IPPG petrographic index with recommendations — a quality control step often required during a real estate transaction.
Do you verify soil compaction in backfill?+
Yes. We measure in-place density with a nuclear gauge, compare it to the Proctor value and document each zone, with grain-size analysis of borrow materials when required.
