- Suitable for use where the substrate does not have the strength to resist stresses caused by water pressure.
- Can accommodate slight movements within the structure.
- Minimal surface preparation is required.
- Loose-laid and fixed to the wall using surface plugs.
- Once fitted, wall surfaces can be dry-lined or plastered and floors can be screeded.
- Can be used to grades 1–3, and is suitable for high water table according to BS 8102:2009.
