URBAN SEAL WATERPROOFING
STP Tank Waterproofing
Sewage Treatment Plants (STP) and industrial wastewater tanks house highly corrosive chemicals, organic sludge, and active bacteria. Protecting these concrete tanks requires heavy-duty chemical-resistant waterproofing systems to prevent concrete erosion and stop wastewater from seeping into surrounding soil or groundwater.
Our STP Tank Sealing Systems
- Chemical-Resistant Epoxy/PU: Application of high-build, solvent-free epoxy or polyurethane linings that resist aggressive wastewater acids, alkalis, and oils.
- Crystalline Sealant Slurry: Concrete crystallization process that locks capillaries, preventing deep moisture ingress and protecting reinforcement steel from rusting.
- Expansion Joint Detailing: Thermal expansion joints and pipe penetration sleeves are detailing-sealed using elastomeric sealants and heavy-duty swellable waterstops.
