| Storage and Handling Store in dry and clean environment in its current packaging. The tape should not be exposed to long periods of ultraviolet light. Prior to use to aid adhesion, store in warm conditions above 10°C. | |
| Preparation Ensure the membrane lap area is clean, dry and free from contamination such as dust or sand. Avoid areas of unsupported jointing. | |
| Installation Apply Visqueen RadonBlok Double Sided Tape to the lap area of the laid sheet starting approximately 50mm from the membrane edge. Apply pressure to the tape to ensure the tape has adhered to the membrane. Remove quick release paper from the tape and overlap the adjoining membrane by minimum 150mm and seal with VisqueenPro Single Sided Tape.
Once the tapes are applied, the completed lap should be well rolled with firm pressure to ensure continuity with the adjacent sheet has been achieved. | |
