SewperCoat® is a 100% pure calcium aluminate premix used for the rehabilitation of sewerage structures. It is also used as a lining for most wastewater structures in new construction applications. Because it is 100% calcium aluminate there is no “weak link” in the material to cause potential problems in the H2S environment


Once applied, the unique mineralogy of SewperCoat® inhibits bacterial (Thiobacillus) activity, minimizing the production of sulfuric acid (H2SO4). This process results in a locally raised surface pH in a wastewater structure. This bacterial inhibiting phenomenon is referred to as the “Protective Reactive Barrier Effect” of SewperCoat®  Sewper Coat Web Site >>
