Waterproofing Solution for Concrete ETP-STP Tanks

ETP-STP Tanks Waterproofing

Water tanks, STPs and ETPs are directly exposed to water, contaminants, and chemicals. To protect the concrete from water ingress and harmful chemicals, UNiTEQ Industries has developed a waterproofing system that is combined with chemical resistant coatings. For water tanks, a waterproofing coating is applied over the concrete surface followed by protection plasters and chemical-resistant, food-grade epoxy coatings. Coal tar epoxy is used for STP/ETP tanks.


An advanced generation, 100% solids, high-build epoxy for the protection of steel and concrete. It provides excellent resistance to abrasion and is suitable for immersion service in potable water and wastewater environments.
