Xtra-Load Radon DPC is a three layered membrane manufactured from a virgin blend of polyethylene that is designed to prevent ingress of radon gas and prevent ingress of moisture from the foundation into the brickwork. The membrane has a grained top and bottom surface for optimal friction resistance between the mortar, brick and foundation.
Features & Benefits
- Ease of application
- Compatible with most construction materials
- Resistant to tearing
- Compatible with all forms of DPM
- Joints and seals easily
- High water vapour resistance
- Radon resistant
- NSA Agrément approved; Certificate No. 09/0328

Installation Details
Installation Procedure: Xtra-Load Radon DPC should be placed along the entire length of each wall. It should be dressed down to meet the sand blinding or substrate and return horizontally a minimum of 100 mm to ensure correct lap and sealing with the Monarflex radon, air and moisture membrane.
Details: All radon DPC’s must exit above external ground level. Where the length of the radon DPC downstand in the cavity is deemed insufficient, an additional stepped DPC should be added. The Xtra-Load Radon DPC should be installed and fixed in accordance with the manufacturer’s
instructions.
Jointing: To form joints between adjacent sheets of Monarflex Easi- Load Radon DPC and Monarflex radon, air and moisture membranes lap the membrane by a minimum of 150mm and seal with a strip of 30mm wide Monobond RT tape.
Penetrations: Where service ducts or pipes penetrate the membrane, gas tight joints are sealed using Monobond RT tape, along with top hat units with retention clips. Complex junctions around penetrations may be sealed by using Easi-Pour Liquid Radon Sealant
Quality Assurance
Xtra-Load Radon DPC is manufactured under a Quality Management System approved to ISO 9001: 2000 by BSI Quality Assurance.
