Learn more about Membrane Fixing Plugs

Membrane Plugs

At Permagard, we stock a wide range of membrane fixing plugs. These high quality membrane plugs allow you to quickly and securely fix membranes to various substrates including brick, concrete, stone and even friable surfaces. Our range spans mesh plugs and clear membrane plugs for both above and below ground scenarios. It’s worth pointing out that some people refer to these fixings as tanking membrane plugs.


If you’re looking to plug holes left by DPC injection then you’ll need our DPC Injection Plugs


Our PermaSEAL membrane plugs are quick and easy to use, providing a secure fixing and preventing water seeping through. When a membrane fixing plug is hammered home with a rubber mallet, the seal is compressed and the plug is firmly embedded into the substrate. For friable surfaces, we offer Cob Fixing Plugs.  

Membrane Plugs with or without seals

We offer membrane fixing plugs with and without washers / seals depending on your requirements and preferences. Some plugs come with rubber grommets in-built for convenience, others take separate washers or are more suitable for sealing by rope to provide that all important waterproof seal. 

Membrane fixing plugs

These PermaSEAL membrane fixing plugs are designed to secure clear membranes to your wall or substrate:  

  • PermaSEAL Quick Membrane Plugs - ideal for non-mesh damp proofing and cavity drain membranes such as PermaSEAL 8 Clear. Features an in-built rubber grommet that creates a compression seal against the membrane to prevent any water ingress. Also, features a preformed hole in the head of plug allowing battens or tracking systems to be secured to it.
  • PermaSEAL Brick Membrane Plugs - generally used for securing clear membranes directly into brickwork, will also work with mesh membranes. We also stock PermaSEAL Brick Membrane Plugs with Seals already integrated.
  • PermaSEAL Cob Plugs - 60mm, 90mm, 110mm, 130mm - generally used on either mesh or clear membranes for fixing into friable substrates. Features an expansion pin to provide the most secure fixing. We recommend using Cob Membrane Plugs with PermaSEAL rope for the best seal.

We also stock Plug sealing washers for use with our membrane fixing plugs.
