Structural epoxy is commonly used in wastewater collection systems due to its high chemical resistance and durability. Wastewater collection systems are subject to aggressive chemical environments that can cause corrosion and deterioration of concrete and steel infrastructure over time. The use of structural epoxy coatings, like EpoxyTec CPP Sprayliner or CPP Troweliner can protect wastewater collection systems from these harsh conditions and extend the service life of the infrastructure.
Here are some specific reasons why structural epoxy is commonly used in wastewater collection systems:
- Chemical Resistance: Epoxy coatings are highly resistant to a wide range of chemicals found in wastewater, such as hydrogen sulfide, sulfuric acid, and other acids and bases. This chemical resistance can help prevent corrosion and deterioration of the underlying substrate.
- Water Resistance: Epoxy coatings are impermeable to water, which can help prevent water Inflow and Infiltration (I&I) into the substrate and protect against freeze-thaw damage. I&I can cost public utilities hundreds of thousands if not millions of dollars over time, treating clean ground water that makes its way to the treatment plant.
- Adhesion: Epoxy coatings have excellent adhesion to concrete and steel substrates, providing a strong bond that can help prevent coating delamination and failure, as well as holding backside water pressure back stopping or substantially reducing I&I, as mentioned above.
- Durability: Epoxy coatings are highly durable and can withstand heavy traffic, impact, and abrasion.
- Easy Application: Epoxy coatings are easy to apply and can be applied in a variety of thicknesses, making them suitable for a range of wastewater collection system components, such as manholes, lift stations, and piping.
Overall, the use of structural epoxy coatings in wastewater collection systems can provide a long-lasting, cost-effective solution for protecting critical infrastructure from the harsh chemical and environmental conditions present in wastewater systems. Further, the investment in a structural epoxy system, like EpoxyTec CPP, can pay for themselves over time by minimizing the investment a utility will need to make in increased treatment capacity and flow.
