Roof and slab waterproofing

Liquid polyurethane waterproofing for slabs and roofs is the application of a continuous, flexible and waterproof membrane on surfaces exposed to weather. The system consists of direct application of a primer, one or more layers of liquid PU (single or bicomponent) applied by roller, brush or spray, and optionally a UV protection layer (aliphatic) or a ceramic finish.

The main advantage of liquid PU over traditional asphaltic membranes is continuity — no joints, no vulnerability points. The PU membrane wraps complex details (drains, pipes, corners) without the need for special accessories. Durability is significantly superior in correct installations: 15 to 25 years versus 5 to 10 years for asphaltic membrane.

Aromatic systems are used in lower layers or applications without direct UV exposure (covered slabs, inter-floor insulation). Aliphatic systems are used on exposed surfaces — more expensive but UV-stable long-term.
