PermaSEAL 8 Clear is a cavity drain waterproofing membrane for use internally, both above and below ground. It’s suitable for walls, floors & vaulted ceilings.
Clear Cavity Drain Membrane
PermaSEAL 8 Clear is a high quality, high density polyethylene (HDPE) membrane. With a stud depth of 8mm, this versatile clear membrane is suitable as both a wall and floor membrane.
PermaSEAL 8 can be used in the following applications:
- waterproofing structures below ground level such as basements, cellars, soffits, vaulted ceilings (provides Type C protection)
- isolating damp walls above ground level
The 8mm stud profile provides 5.3 litres of drainage volume per m2.
Type C waterproofing
PermaSEAL 8 Clear is a clear cavity drain membrane. It is suitable for use in accordance with BS8102:2022 to provide ‘Type C drained protection’ to structures below ground. It also provides a Grade 3 dry environment suitable for domestic or commercial use.
When you are looking to achieve ‘Type C’ protection, you will need to use a PermaSEAL Sump and Pump system in conjunction with this clear basement membrane (unless passive drainage is available on one side of the building). It also needs to be maintained throughout the lifetime of the installation.
