INSTALLATION
Taped system,
- Ensure the surface is dry and dust free before unrolling.
- Once the membrane is flat, apply the double-sided butyl tape (50mm width) approximately 50mm from the edge, and temporarily leave the backing paper on.
- Prepare the second length of radon barrier by once again ensuring the surface underneath is dry and dust free.
- Then lay the second length of membrane with a 150mm overlap on to the first length of membrane.
- Join them together by unpeeling the backing paper of the double-sided butyl tape.
- It is recommended to apply firm pressure along all joints to form a strong sealing bond.
- Where the two membranes overlap, the excess membrane needs to be stuck firmly in place using a single-sided lap tape.
- Apply this tape equidistant over the two membranes and apply firm pressure to complete the seal.
Welded system,
- When installing the membrane, welding should be undertaken by competent and experienced person.
- Tests should be undertaken prior to welding, to ensure the correct temperature and speed is achieved.
- Novia 1600g Radon Barrier should weld between 180 - 230°C and 2-3m per minute.
- The joint to be welded should be overlapped by 100mm as a minimum, with a 50mm wide weld.
- Welds on gas membranes are subject to independent verification in accordance with CIRIA C735. This includes joint integrity testing.
