✔ Quick & Easy Installation – Minimal surface preparation required for fast application.
✔ Flexible Application – Can be used with timber battens, steel dry lining, and other fixing systems.
✔ Works with Perimeter Drainage Systems – Optimises waterflow toward sump locations.
✔ No Drying Time Needed – Immediate redecoration possible after installation.
✔ Minimal Structural Impact – No damage to walls or floors, preserving existing structures.
✔ Easily Folded & Cut – Adapts around windows, doors, and corners.
✔ Durable & Resistant – Waterproof, salt inhibiting, and contaminant resistant.
✔ Temperature Tolerant – Performs in both low and high temperatures.

Ideal Applications:

✔ Basement & Cellar Waterproofing (walls & floors for a dry, usable space)
✔ Structural Damp Protection (prevents moisture ingress in underground structures)
✔ New & Retrofit Installations (works with existing and new construction projects)
✔ Perimeter Drainage & Sump Systems (optimises waterflow control in waterproofing systems)
