At GMT Lab, we analyze soils to ensure the safety and stability of your construction projects.

Our teams perform on-site sampling and laboratory testing to determine the nature, bearing capacity, compactness and behaviour of the soil.

This data makes it possible to design suitable foundations, anticipate risks and ensure the reliability of your structures.

With GMT Lab, you have access to precise expertise and reliable results so you can build with full confidence.<\/div>\t\t\t\t\t<\/div>\r\n\t<\/div>\r\n\t\r\n<\/div>\r\n\r\n\r\n\r\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

We perform a wide range of laboratory tests to ensure the quality and compliance of the materials used in your construction projects.

Concrete: we verify the strength, durability, composition and performance of fresh and hardened concrete to ensure the reliability of structures.

Soils: our analyses determine the nature and physical properties of soils for various studies and applications.

Aggregates: we verify the compliance of granular materials to ensure they meet applicable standards and uses.

With GMT Lab, you benefit from accurate results, rigorous quality control and technical support for high-performance materials and durable projects.<\/div>\t\t\t\t\t<\/div>\r\n\t<\/div>\r\n\t\r\n<\/div>\r\n\r\n\r\n\r\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Quality control (QC) in geotechnics encompasses all the verifications, tests, inspections and technical follow-ups carried out to ensure that materials, construction methods and geotechnical works (foundations, fills, piles, concrete, granular materials, etc.) meet project requirements, technical standards and engineering best practices.

- In situ density test (compaction test on aggregate)
- Tests on fresh and hardened concrete
- Verification of foundation soils for buildings, roads, infrastructure, etc.
- Approval of grain-size analysis sheets, asphalt mix-design formulas, and concrete mix-design formulas
- Supervision of asphalt placement<\/div>\t\t\t\t\t<\/div>\r\n\t<\/div>\r\n\t\r\n<\/div>\r\n\r\n\r\n\r\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
