Damp Proof Membrane Fixing Plugs & Pins – Expanding Wall Fixings
Secure Fixings for Damp Proof Membrane Systems
These Damp Proof Membrane Fixing Plugs and Pins are designed for securing suitable damp proof membrane systems to walls in above-ground applications.
Ideal for damp proofing projects, wall membrane installations and cellar or basement conversions, these fixings provide a practical method of attaching membrane systems to suitable substrates.
The fixing consists of a plug with a separate expanding pin. When the pin is inserted into the plug, it causes the fixing to expand, providing additional grip within the fixing hole.
Key Features & Benefits
- Expanding Fixing Design – The pin expands the plug to provide additional grip.
- Designed for Membrane Systems – Suitable for securing compatible damp proof membranes.
- Above-Ground Applications – Intended for use above ground level.
- Two-Part Fixing – Supplied as a plug and separate expanding pin.
- Simple Mechanical Fixing – Designed to hold membrane in position against a suitable wall substrate.
- Damp Proofing Projects – Useful for membrane installation and remedial damp proofing work.
- Cellar & Basement Conversions – Suitable for specified above-ground membrane fixing applications within conversion projects.
How the Expanding Plug & Pin Works
The plug is positioned through the damp proof membrane into a suitably prepared fixing hole in the wall.
The separate pin is then inserted into the plug, causing the plug to expand and increase its grip within the substrate.
This expansion helps secure the membrane fixing in place.
The correct installation method, hole size and fixing spacing should follow the membrane system manufacturer’s recommendations.
Suitable Applications
These expanding plugs and pins are intended for use in compatible applications including:
- Above-ground damp proof membrane installations
- Internal wall membrane fixing
- Remedial damp proofing systems
- Cellar conversion projects
- Basement conversion projects
- Suitable wall membrane systems
Important Installation Information
These fixings are intended for above-ground applications. Where a membrane system is designed to resist groundwater pressure or forms part of a below-ground waterproofing system, the fixing and sealing method must be approved for that particular installation.
Always check compatibility with the membrane, wall substrate and waterproofing specification before installation.
Frequently Asked Questions
What are damp proof membrane plugs and pins used for?
They are used to mechanically secure compatible damp proof membrane systems to suitable wall substrates.
How does the expanding pin work?
The pin is inserted into the plug, causing the plug to expand and provide additional grip inside the fixing hole.
Can these fixings be used in basement conversions?
Yes, they can be used for specified above-ground membrane fixing applications associated with cellar and basement conversions. Below-ground waterproofing applications require an appropriately specified fixing and sealing system.
Are these suitable for all damp proof membranes?
Compatibility depends on the membrane system, wall substrate and fixing requirements. Always follow the relevant installation specification.
