Matériaux d'Étanchéité et Barrières
Membranes barrières anti-radon certifiées par coefficient de diffusion selon ISO/TS 11665-13. Comprend des membranes bitumineuses (SBS/APP), des membranes en polyéthylène HDPE/LDPE, des barrières liquides pour gaz, des systèmes de polyuréthane projeté, des mastics pour fissures et joints, et des joints d'étanchéité pour pénétrations de tuyaux. Essentiels dans la construction neuve et efficaces lorsqu'ils sont combinés avec une dépressurisation active, bien que non recommandés comme solution autonome.
Application
Intervention Type
Radon barriers and membranes reduce both diffusion and convection, providing passive protection when properly installed. From bituminous sheets to polyethylene membranes and projected systems.
Browse certified products from manufacturers including Danosa, Soprema, and Visqueen. Best used as complementary measures with active depressurization systems.
