Wastewater Coatings San Antonio: Protecting Sewers and Manholes
Specialty Coating Products (SCP) provides wastewater coatings in San Antonio, Austin, and across Central Texas, helping owners, engineers, and applicators protect critical sewer and manhole infrastructure. Whether you’re facing chemical induced corrosion and I&I, or you need an impermeable membrane, a liquid applied coating, or troweled cement, our team has the expertise to solve it.
Why Wastewater Coatings Matter
Concrete and steel in wastewater environments take constant punishment from microbes and hydrogen sulfide. These two forces drive most of the corrosion we see in sewers, manholes, and treatment plant structures. Because of this, SCP builds its tank linings, secondary containment coatings, and cement products to withstand the harshest chemical conditions, extending the life of the assets our customers depend on. Our line includes 100% solids epoxy and polyurea, calcium aluminate, and cement filler and patching products. Our featured systems are SCP DropLiner and ReLiner from Standard Cement, specified by Austin Water and SAWS respectively. You can read more about the science behind DropLiner in our post on H2S corrosion protection.
SCP DropLiner is a fast-set, spray-applied polyurea coating system designed for the most demanding wastewater and industrial environments across Texas. Engineered as a 100% solids, zero-VOC system, DropLiner forms a seamless waterproof membrane for both steel and concrete substrates where long-term corrosion protection is critical. Manufactured and supplied through Specialty Coating Products, SCP DropLiner is purpose-built for infrastructure exposed to hydrogen sulfide (H₂S), constant moisture, abrasion, and aggressive wastewater conditions. Product features include:
- Formulated for water treatment and wastewater applications, including aeration basins, manholes, lift stations, and sewage exposure
- Excellent H2S corrosion protection and resistance
- Superior elongation (425%), which protects against soil stress and substrate movement
- High abrasion resistance for harsh environments
- Seamless monolithic waterproof membrane, which eliminates I&I in collection systems
- Odorless, non toxic vapors
- Sets up in 10 seconds, which helps minimize pinholes
Reliner MSP Cement: Structural Repair for Sewer Infrastructure
Reliner MSP Cement from Standard Cement is a factory blended, packaged cement built for new and existing sewer infrastructure. It is formulated with densified microsilica powder, pozzolan, and Geopolymer alongside select admixtures, so it restores structural integrity, stops water infiltration, and protects against corrosion. Because of this versatility, crews use it in sewers, manholes, wet wells, lift stations, pipes, corrugated culvert pipes (CMP), dams, tunnels, and water treatment plant structures. Reliner MSP Cement is made with cement for both bulk and bag products.
Trusted Wastewater Coatings for Texas’ Largest Municipal Suppliers
SCP supplies SCP DropLiner, Standard Cement materials, and Carboline coatings and linings for the wastewater market. As a result, Texas’ largest municipal water suppliers, SAWS and Austin Water, list our brands on their SPL (Standard Products List). We regularly recommend solutions for treatment plant components like clarifiers, digesters, and headworks, as well as sewer system assets where I&I and hydrostatic pressure create ongoing challenges. We also work closely with prominent consulting engineers whose specification focus is wastewater exclusively.
