Imperméabilisation des fondations

Underslab vapour barrier systems are traditionally installed beneath concrete slabs to prevent the upward migration of soil gases such as radon, methane, and moisture vapour. The system is also designed to resist hydrocarbons that may be present in the soil. These high-performance hybrid HDPE and PMAE membranes create a continuous monolithic seal that enhance indoor air quality, protects sensitive building materials, and supports compliance with health and safety standards. Underslab vapour barriers are a critical component of gas mitigation strategies across all building types.
