Description :

PermaSEAL 3 Clear is a translucent high-density polyethylene (HDPE) membrane for damp proofing and waterproofing walls, floors and ceilings in new or existing buildings. It can be used above or below ground, over a contaminated or damp background, to support a dry lining or flooring system. The system is approved for use in Type C (drained protection) constructions in accordance with BS 8102:2022.
PermaSEAL 3 Clear 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 Clear 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.
