Tested. Proven. Certified.

Our tested, proven and certified geotechnical products are designed to meet the required specifications of your project. They offer a high-performance antifreeze layer for all road and railroad construction, as well as buried utility lines, protecting against extreme temperature variations and repeated freeze-thaw cycles that may cause premature damage.


Road. Access road. Unstable ground. 

Featuring high compressive, flexural and shear resistance, our expanded polystyrene insulation shines when it comes to the distribution of loads and tensions, helping to prevent the collapse of structures and protect your construction projects.


Durable. Economic. Lightweight.

Offering a high insulation value as well as water and moisture resistance, our products maintain their performance characteristics, meaning they will not lose efficiency over time. Lightweight, they are easy to handle and do not create additional loads that could affect the structure. Isolofoam expanded polystyrene geotechnical insulation is a cost-effective solution for civil engineering projects.
