Introducing our cutting-edge Damp Proof Membrane (DPM), your ultimate solution to safeguarding your property against moisture-related issues. Say goodbye to the headaches of dampness, mold, and structural damage with our top-of-the-line membrane that stands as a fortress against unwanted water infiltration. Crafted with precision and innovation, our DPM is the epitome of reliability and durability, providing you with peace of mind for years to come.
In the realm of underfloor heating installations, the incorporation of a damp proof membrane (DPM) emerges as a crucial element to ensure optimal performance and longevity of the system. Our DPM acts as a robust shield, impervious to moisture, preventing any water ingress that could potentially jeopardize the efficiency of the underfloor heating system. By creating a barrier between the subfloor and the heating elements, our membrane safeguards against damp-related issues, such as corrosion and degradation, ensuring the system operates at peak performance. Furthermore, the DPM enhances the overall insulation properties, preserving the effectiveness of the underfloor heating by minimizing heat loss through the subfloor. Choosing our Damp Proof Membrane is not just a precautionary measure; it's a strategic investment to guarantee the sustained excellence and durability of your underfloor heating system.

Lapping And Jointing
- Clean all surfaces and make sure they are clean, dry, free of grease, mortar and any other debris.
- The jointing of all top-hats, DPC, cavity trays and membranes should be done in warm ambient temperatures. Do not attempt to joint below 5°C. Warming may be required if jointing below 10°C.
- Apply as much pressure as possible to the area being jointed with membrane double sided tape. A standard wall paper roller makes a great tool for this job.
- Ensure membrane is protected with a screed or protection board if the installation is to be topped with steel reinforcement.
- Avoid all traffic on unprotected membrane. Only install the membrane just before the laying of any screed – reducing the amount on unnecessary traffic on the unprotected membrane.
- Ensure sufficient screed is laid to protect the membrane. Screed should be laid at 55mm thick across all areas of the membrane.
Jointing Of Membrane
- Unroll the first membrane, ensure the surface is dry and free from dust or grease. Inspect the membrane to ensure that there are no indentations or protrusions. If there are remove and apply sand blinding.
- Apply Radbar Double Sided Tape to the membrane, 50mm from the edge. It is very important that the membrane is dry and free from dust and dirt.
- The second membrane must be unrolled overlapping the first membrane by 150mm. Remove the protective paper from the Radbar Double Sided Tape; apply pressure to the membrane while joining the two membranes together.
- Seal the two membranes by installing Radbar Single Sided Tape to the edge. (ensure that the membrane is completely dry, free from dust and dirt.
