Waterproof Floor Membrane - 20m²
PermaSEAL 20 Floor Membrane is primarily designed as a high capacity floor cavity drainage membrane. The 20mm stud profile creates a large 14 Litre per square metre void, ideal for areas of high levels of water ingress and water movement. It can also be used as a high performance drainage membrane solution for walls or vaulted soffits where extremely high levels of water ingress are a problem. PermaSEAL 20 is also used in tunnels, civil construction and for commercial properties.
The PermaSEAL 20 basement floor membrane is guaranteed against deterioration for 30 years and has a life expectancy of at least 50 year. This basement floor waterproofing membrane is an inert product with high pressure 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.
Installing a Basement Floor Membrane
If a below ground waterproofing system is being installed then the floor membrane should be used with our Drainage Channel and Floordrain perimeter drainage systems. Our innovative PermaSEAL Quick Plug is recommended when fitting PermaSEAL 20 to the wall.

Fantastic priceFantastic price with the assured quality of PermaSEAL, also I have been waiting for a manufacturer to produce a smaller version of the 20mm floor membrane which in turn is lighter and easy to handle for one person. Thumbs up from me!
