Effective HDPE Waterproofing Solution

UberSeal 8mm Clear Membrane is crafted from high-density polyethylene (HDPE), featuring a high-quality 8mm stud depth. This clear, versatile membrane is designed for both wall and floor applications, offering robust waterproofing solutions ideal for:

  • Waterproofing subterranean structures like basements and cellars, along with soffits and vaulted ceilings.
  • Isolating dampness in above-ground walls.
  • Areas that require protection from high levels of water ingress.

What's Type C protection?

"Type C" waterproofing involves managing water ingress through a drained cavity system, using cavity drain membranes to channel water to a drainage system, often incorporating sump and pump mechanisms. This method is adaptable and effective for below-ground structures, requiring regular maintenance to ensure functionality.

As a clear cavity drain membrane, UberSeal 8mm Clear Membrane offers "Type C" drained protection which is perfect for basements and cellars, ensuring a Grade 3 dry environment suitable for both residential and commercial settings. However, achieving full "Type C" protection necessitates the use of a UberSeal Sump and Pump system alongside this membrane, except in cases where passive drainage is feasible. Regular maintenance is essential to uphold the system’s integrity over its lifespan.


Compatibility and Finishes:

This membrane accommodates a variety of finishes, whilst UberSeal Brick Plugs are designed to support screws, allowing for the addition of batons, metal lath systems, and insulation prior to plasterboard finishing.

Furthermore, it enables the construction of fixtures, fittings, walls, and staircases directly off the membrane. As a floor membrane, it supports insulation, underfloor heating, screed, and floating floors, offering a comprehensive solution for waterproofing needs.
