PermaSEAL 3 Mesh is a translucent high-density polyethylene (HDPE) membrane for damp proofing and waterproofing walls and ceilings in new or existing buildings. It can be used above or below ground over a contaminated or damp background to support dot and dab plasterboard or a render system. The system is approved for use in Type C (drained protection) constructions in accordance with BS 8102:2022.
PermaSEAL 3 Mesh is guaranteed against deterioration for 30 years and has a life expectancy equal to the design life of the structure (DIN 9001:2000). The membrane must have permanent protection from UV light and physical damage along with the correct specification and installation in order to achieve the life expectancy.
PermaSEAL 3 Mesh is an inert product with high compressive loading stability. It is highly resistant to water alkalis saline solutions and organic acids and is not affected by minerals. It is also resistant to bacteria fungi and other small organisms. When a below ground waterproofing system is specified it is essential the cavity drain system incorporates the PermaSEAL drainage system including sump and pump system.
