Rail, airports, public buildings & parks
Stations, airports, public buildings.
The right layers, in the right order, on schedule.
Elevated station walkways, airport roofs, cracks in public buildings and park paths: we choose the system that fits, then build it up in the right order, from substrate to top coat. When PASSAWARN installs, the manufacturer’s warranty applies.

Elevated station walkway waterproofing
Walkways round the station and the floors around equipment get two coats of flexible cementitious waterproofing, with joints and cracks treated separately, to keep water from dripping onto the platforms and roads below.
- Cementitious waterproofing, coat 2Applied once the first coat has set, to build an even thickness.
- Cementitious waterproofing, coat 1Applied to the damp substrate. It bonds with the concrete to stop water.
- Concrete (pre-dampened)Soaked with water, surface left just dry, so it won’t draw water out of the coating.substrate
Layer thicknesses are exaggerated for clarity. Built up from the bottom.
