Frequently Asked Questions
What is a sheet membrane used for?
A sheet membrane is a continuous waterproof barrier applied to below-grade walls, roofs, planter boxes, and retaining walls. It stops water ingress through the structure. Sheet membranes come in PVC, butyl rubber, and HDPE, each suited to different site conditions.
How do I choose between a PVC and a butyl rubber sheet membrane?
PVC sheet membranes are heat-welded at the seams to form one continuous layer. Butyl rubber sheets are self-adhesive and press into place without torches. PVC suits large roof areas and planter boxes. Butyl rubber suits detail work, penetrations, and tight spaces.
Can I use a sheet membrane in a bathroom?
The sheet membranes in this store are for below-grade tanking, planter boxes, retaining walls, and roofs. For internal wet areas such as bathrooms and showers, a liquid or cementitious membrane is the right choice. Those systems handle the internal corners and penetrations more directly.
What does heat-welded mean for a sheet membrane?
Heat-welding uses a hot-air gun to fuse the overlap of two PVC sheets into one sealed seam. The bond is as strong as the sheet itself. This method creates a watertight joint without adhesives, tapes, or primers at the seam.
Do I need a primer under a sheet membrane?
It depends on the substrate and the sheet. Self-adhesive butyl rubber sheets need a clean, primed surface to bond. PVC heat-welded sheets may not require a primer on concrete but need one on porous or dusty substrates. Check the specific product instructions.
