A robust and durable waterproofing solution

The UberSeal 8mm Mesh Membrane sets the standard in basement wall waterproofing solutions, distinguished by its high-quality, 0.65mm high-density polyethylene construction. Engineered to be one of the toughest and robust membranes available, it integrates a mesh welded to its surface, facilitating direct rendering or dot and dab finishes. This feature not only enhances its durability but also its versatility, making it capable of withstanding the rigors of everyday site impact damage with ease.



Installation of the UberSeal 8mm Mesh Membrane requires UberSeal Plaster Plugs or Brick Plugs for attachment to target walls. The plugs should also be sealed by applying either Brick Plug Sealing Washers or UberSeal Butyl Rope firmly around the head of the plug to create a waterproof seal before they are hammered into place.

The following is the recommended application method:

  1. Ensure the base is cleaned to achieve the smoothest surface possible. Eliminate any plaster that is damaged, loose, or disintegrating.
  2. Use a sharp blade or scissors to trim the membrane to the desired dimensions.
  3. Secure the 3mm membrane (mesh side exposed) to the surface using plugs. Installation can be either horizontal or vertical. 


Approximately 15 plugs per square meter are recommended, each plug should be no further than 250mm horizontally or vertically from one another. On curved or uneven surfaces, plugs/fixings should be closer together to ensure that the mesh is not too loose from the wall.

Jointing - The 8mm mesh membrane is highly flexible and can be effortlessly moulded around corners. As an alternative, edges can be brought together (butt jointed) and made watertight with UberSeal Fleece Overstrip.

Finishing - Plasterboard panels can be attached to the membrane using the dot and dab technique, ensuring at least 50% of the board is covered with the adhesive dabs. This provides a dry surface that is primed for instant decoration.


Beyond its physical resilience, the UberSeal 8mm Mesh Membrane excels as a substrate for lime mortars, renders, and plasters, thanks to the design of its square 8mm studs that adeptly manage corner detailing and surface irregularities. Paired with our recommended drainage solutions it promises a waterproofing installation of unmatched reliability and performance.
