Submersion & Potable Water Quality Challenge
Water storage structures require waterproofing systems that are permanently submerged, resistant to constant hydrostatic pressure, and chemically stable. For potable water reservoirs, the primary concern is the prevention of chemical leaching, bacterial growth, and contamination, which must comply with strict food-grade and public health standards. Water tanks also experience structural expansion and cracking under varying load conditions.
Application Selection Guidance
Specify Geobit non-toxic, food-grade 2K cementitious coatings or specialized polyurethane lining systems for internal potable water surfaces. These systems conform to ASTM and BS EN standards for contact with drinking water. For external positive-side protection, apply rubberized bitumen or cementitious coatings to prevent groundwater ingress. Concrete joints must be treated with food-safe PVC waterstops or swellable hydrophilic profiles.
Pressure washing and repairing internal concrete walls with non-shrink structural grout.
Heavy-duty internal PVC waterstops placed across tank floor and wall joints.
Potable water certified 100% pure spray polyurea producing a seamless monolithic elastomeric lining.
Non-toxic epoxy or polyurea lining certified for safe drinking water storage.
Water pressure testing and water purity verification prior to commissioning.
