Frequently Asked Questions
What do I use to waterproof a civil structure?
Membranes, waterstops, drainage components, and protection layers. The range includes cementitious and polyurethane membranes, pre-applied tanking, swell waterstops, geo fabric, protection board, and wall drainage. Pick the product that matches your substrate and exposure.
How do I choose between a cementitious and a polyurethane membrane?
Cementitious membranes suit positive-side waterproofing on concrete and masonry where movement is low. Polyurethane membranes handle movement, complex shapes, and exposed conditions better. Check the technical data for movement capability, cure, and exposure limits before you decide.
Will a membrane work on a moving joint?
Not on its own. Membranes on moving joints need a compatible sealant or waterstop at the joint line. Use a swell waterstop or a polyurethane hybrid at the joint, then protect the membrane over the rest of the surface.
What is a swell waterstop and when do I use one?
A swell waterstop is a strip that expands when it contacts water, sealing cracks and construction joints. Use it at concrete joints, around penetrations, and where two pours meet. Place it before the pour.
Do I need protection board over a waterproofing membrane?
Yes, if the membrane will take traffic, backfill, or other construction traffic before the next trade covers it. Protection board protects the membrane from damage during the build. Match the board thickness and core to the load and the exposure.
Can I paint over a waterproofing membrane?
Some can, some cannot. Check the product technical data for paint compatibility and the recommended overcoat. Polyurethane membranes may accept specific coatings. Cementitious membranes often take tile or paint once cured. Do not paint a membrane without confirming compatibility first.
