Water treatment plants, reservoirs & wastewater plants
Clean water and wastewater.
Kept in by the right layers.
From water-treatment basins and wastewater tank linings to construction joints, leaking cracks and plant-building roofs: we choose the system for the water and chemicals involved, then build it up in the right order, from substrate to top coat. When PASSAWARN installs, the manufacturer’s warranty applies.
