Waterproofing
Polyurethane SystemsPolyurethane Liquid Membrane — 1-Component
Ready-to-use seamless waterproofing for demanding exposed surfaces.
Overview
A one-component, moisture-curing aliphatic polyurethane liquid membrane applied cold by roller, brush, or spray. On contact with atmospheric humidity, the material cross-links to form a seamless, permanently elastic, UV-stable waterproof layer. Requires no mixing, delivers consistent results, and remains flexible from −30 °C to +80 °C — handling substrate movement, thermal cycling, and minor cracking without loss of waterproofing performance. Suitable for exposed terraces, balconies, and accessible roofs.
Key benefits
- ▸Ready to use — no mixing required, consistent quality every application
- ▸UV-stable aliphatic chemistry — suitable for permanently exposed, uncoated surfaces
- ▸Elongation >400% — bridges substrate cracks and accommodates structural movement
- ▸Cold application — no open flame, no hot-works permit required
- ▸Trafficable grades available for light pedestrian and maintenance access
- ▸Overcoatable with colour finish or anti-slip aggregate topping
Applications
- Exposed terraces and accessible flat roofs
- Balconies, podium decks, and planted roof planters
- Wet areas, shower trays, and bathrooms
