Water treatment plant waterproofing

Water treatment plants (WTPs) and sewage treatment plants (STPs) have various concrete tanks and structures that require robust waterproofing and specific chemical resistance: coagulation tanks, flocculators, sedimentation tanks, filters, disinfection reservoirs (with residual chlorine), ozone reaction tanks, anaerobic digesters. These environments combine aggressive chemical exposure (treatment products), permanent humidity, thermal variations and concrete structural movements. Spray-applied PU coatings offer advantages over conventional paints: monolithic membrane without joints, exceptional concrete adhesion, flexibility to accommodate movements, specific chemical resistance when properly formulated, rapid application in complex geometries. Segment growing driven by: sanitation expansion in emerging markets (Brazil has significant deficit to be supplied), modernization of aging stations in developed markets, and growing water reuse requirements in industries.
