Waterproofing For Sewage Treatment Pool
2016 Ningbo coastal sewage pool renovation uses PS500D sewage treatment pool polyurea coating, delivering durable waterproof and anticorrosive protection for humid coastal industrial sewage facilities.
Completed in 2016, this industrial protection project was carried out on multiple sewage treatment pools in Ningbo, a coastal city with high humidity and saline atmospheric environment. Facing persistent corrosive wastewater erosion and humid coastal climate, the facility required a highly durable lining solution. Our team applied professional PS500D Sewage Treatment Pool Polyurea Coating for full waterproofing and anticorrosive renovation of concrete pool structures.
Site Environmental & Structural Challenges
Coastal Ningbo features humid marine climate, frequent humid wind and salt-containing air. The on-site sewage pools run continuously all year round, bearing complex medium erosion including industrial wastewater, organic pollutants, acid-base substances and long-term water immersion.
Traditional waterproof and anticorrosive materials are prone to blistering, delamination and aging failure under long-term alternating damp environment and chemical corrosion. Damaged lining leads to concrete carbonization, sewage leakage, secondary pollution and frequent facility maintenance shutdowns, bringing high operational pressure to the sewage treatment station.
Customized Protection Solution with PS500D Polyurea Coating
Considering the harsh operating conditions of coastal sewage facilities, we adopted PS500D professional polyurea coating exclusively designed for sewage pool protection. The material forms an integral, seamless high-density protective film after spraying, completely covering concrete base pores and micro cracks. It effectively isolates various corrosive sewage media from direct contact with the structural concrete.
With excellent chemical resistance, the PS500D polyurea layer remains stable under long-term erosion of mixed industrial sewage. It maintains strong adhesion and flexible toughness in humid coastal environment, avoiding peeling and cracking caused by climate changes and structural slight deformation. The overall construction forms a fully enclosed anticorrosive and waterproof system, greatly improving the durability of sewage pool facilities.
Long-Term Operation Effect
After the completion of renovation in 2016, the PS500D polyurea coating layer has maintained stable waterproof and anticorrosive performance during long-term continuous operation. It completely solves common problems such as pool seepage, lining aging and concrete corrosion. The sewage treatment facility realizes long-term stable operation with greatly reduced manual maintenance frequency and operational cost.
This PS500D sewage-specific polyurea coating is highly suitable for urban sewage treatment plants, industrial wastewater pools, sedimentation tanks and various concrete anti-corrosion and waterproof projects in coastal humid areas.
