Waterproofing membranes have improved over the years. It is more than just a barrier to water it must be able to withstand movement in the joints, wall and floor junctions.
Ideally a good waterproofing membrane should:
- Protect the substrate from moisture
- Have a high stress resistance to movement
- Able to be bonded with tiles and other materials with ease
- High resistance to chemical and abrasion products
- Easy to apply safe to handle and non toxic
