FAQs
Is this membrane suitable for basement use?
While it provides an excellent moisture barrier, basement waterproofing often requires specialized cavity drain systems. Consult a structural professional for basement-specific requirements.
Can I use this under floor insulation?
Yes, it is commonly placed under insulation to protect against moisture vapor rising from the ground.
What tape should I use for joints?
Use professional-grade double-sided or single-sided damp-proof membrane tape specifically designed for high-adhesion sealing of polythene sheeting.
How do I cut the membrane?
The polythene can be easily cut using a standard, sharp utility knife or heavy-duty scissors.
Does it have a specific orientation?
There is no functional difference between sides, but ensure the surface is clean before laying it down.
Troubleshooting
Membrane torn during installation
Apply a patch of the same material at least 150mm larger than the tear and seal all edges thoroughly with waterproof damp-proof membrane tape.
Membrane slipping on concrete base
Use temporary weights or a light adhesive spray to hold the membrane in place until the concrete pour stabilizes it.
Pros and Cons
Pros
- Certified BBA approval ensures professional-grade reliability
- Compact 3m x 4m size is ideal for small projects without excess waste
- High-strength polythene resists punctures and tears
- Easy to install and cut to size for custom dimensions
- Effective defense against rising damp and water migration
Cons
- Not suitable for covering large foundation areas without multiple sheets
- Requires proper sealing at joints for full waterproofing integrity
- Lacks adhesive backing, requiring separate tape or sealant
Setup, Compatibility & Care
To install, ensure the ground surface is smooth and cleared of sharp objects that could pierce the material. Unroll the membrane across the area, overlapping adjacent sections by at least 150mm if using multiple sheets. Seal all overlaps and edge penetrations using high-quality damp-proof membrane tape to create a continuous barrier. Once installed, minimize foot traffic on the membrane until the concrete pour is complete. Store the product in a cool, dry place away from direct sunlight when not in use to prevent degradation of the polythene.
