UNIQUE POLYMER SYSTEMS provides robust and long-lasting protective solutions for industrial infrastructure. This case study details the successful repair and protection of corroded steel and degraded concrete at a sewage treatment plant using UPS 405 EPC EPOXY PROTECTIVE COATING, UPS 905 DP DAMP PRIMER, and UPS 920 FFS FASTFILL SCREED.
At a sewage treatment plant, extensive corrosion was found on steel structures, and the concrete surfaces had degraded significantly. These issues posed a serious risk to the structural integrity of the plant, which required immediate attention to prevent further damage and potential operational failures.
The challenge was to repair the damaged concrete and steel surfaces effectively, ensuring that the solution would withstand the harsh conditions of the sewage treatment environment. The solution needed to be durable and provide long-term protection against further corrosion and degradation.
UNIQUE POLYMER SYSTEMS provided a comprehensive repair and protection solution using a combination of UPS products. The application process involved the following steps:
Surface Preparation
- All substrates, including steel and concrete, were abrasive grit blasted to remove contaminants and create a clean surface for the repair materials to adhere to.
- Any remaining contaminants were "sweated" from the surface using appropriate cleaning techniques.
Concrete Repaired with UPS 920 FFS FASTFILL SCREED
- Damaged sections of concrete were rebuilt using UPS 920 FFS, restoring the integrity of the degraded areas and providing a solid foundation for the protective coating.
Priming with UPS 905 DP DAMP PRIMER
- Due to the high moisture content in the substrate, the porous surfaces were primed with UPS 905 DP. This primer ensured proper adhesion of the subsequent protective coating, even in damp conditions.
Application of UPS405 EPC EPOXY PROTECTIVE COATING
- The entire substrate was coated with two layers of UPS 405 EPC, each applied at a nominal thickness of 250 microns. This dual-coat system provided robust protection against future corrosion, ensuring the long-term durability of the repaired areas.
The application of UPS 405 EPC, combined with the repair and priming process, successfully restored and protected the corroded steel and degraded concrete at the sewage treatment plant. The comprehensive solution provided by UNIQUE POLYMER SYSTEMS ensured that the plant's infrastructure would remain protected from further corrosion and degradation.
This case study demonstrates the effectiveness of UNIQUE POLYMER SYSTEMS' repair and protection solutions in safeguarding critical infrastructure within harsh environments. Our advanced materials and precise application techniques delivered a reliable and durable solution that extended the service life of the sewage treatment plant.
