Application
Water Tank Waterproofing
Water tank waterproofing requires materials and detailing rated for continuous or intermittent immersion, potable or non-potable service as applicable, and crack-bridging at joints. Petroseal supports tank projects with cementitious systems, selected liquid coatings, and membrane options where the design allows. Potable-water approvals are only claimed when documented for the specific product batch and market.
