Radbar Gas Resistant DPC - 112.5mm x 20m

Radon DPC – 112.5mm width  

Radbar Radon DPC provides outstanding resistance to radon gas and water vapour. It is designed for use in both solid and cavity walls, acting as a highly effective barrier from harmful ground gases. It is robust with high puncture and tear resistance.

Uses of Radon DPC

The Radbar Radon DPC can be used in walls as a horizontal, vertical or stepped gas resistant DPC. 

It is designed for both solid and cavity walls (when used with a cavity tray system) made from: 

• Brick
• Block
• Stone
• Concrete 

Installation of Radon DPC

The radon DPC is installed in the same as a normal DPC. Therefore, for external walls, the gas DPC should be placed 150mm above the ground floor. It should be applied to a fresh bed of mortar, without any protrusions. 

Make sure the gas-resistant DPC is linked to a damp proof membrane or gas membrane. It’s vitally important you have an air-tight seal between membrane and DPC so use Radbar double-sided gas tape. This damp proof course needs to installed in accordance to building regulations: BS 8215:1991, BS 8000, and BS 5628.  

Benefits of Radbar Radon DPC 

This high performance gas DPC is an engineered tri-polymer, developed to give excellent mechanical properties. It provides a highly effective barrier against both water and gases for the lifetime of the building.

The DPC benefits from a prominent key, which means you get superior mortar adhesion. This is essential when being used in three + storey applications. 

Radbar High Performance DPC is compliant with building regulations - BS EN 14909:2012 – and carries BBA Certification. This provides complete confidence in the product, knowing that it has been manufactured to the highest standard.
