Polyurethane liquid membranes

The last decades has seen the waterproofing community turn to new technologies based on high technology Liquid membranes.

This new school of thought has abandoned the idea that only multi-layer systems guarantee water-tightness.

Liquid-applied systems, of which polyurethane waterproofing membranes are the prime example, offer decisive advantages particularly where seamless systems are desired; either structurally or aesthetically, and for geometrically complicated connections with ventilation outlets or upturns.

Critical to success, is the correct material selection from the various alternatives on the market.
