Warren Environmental – Epoxy Coating for Digester

One Coat. 75 Years.

About the Company:

Warren Environmental epoxy coatings are highly resistant to H2S and tolerant of very low pH. Their 100% solids epoxies protect pipes and entire wastewater systems to stop inflow and infiltration (I&I), while enhancing structural properties.

They specifically formulated epoxy blends to solve issues with corrosion, microbial attack, and sewer gases while extending the service life of your high-value assets for over 75 years. Their products will reduce your risks while minimizing operational disruptions.

About the Solution:

Warren’s epoxy coating system is a quick and effective rehabilitation method that adds valuable service life to anaerobic digester tanks with minimal impact on their operations.

Warren’s approved applicators use 301-14 epoxy to repair tank’s concrete surfaces. Before coating the walls, the team sandblasted and water blasted to remove loose concrete. Afterward, they spray applied 375-500 mils of Warren’s 301-14 epoxy to the concrete surfaces. Areas with exposed rebar required repair with Warren’s epoxy mastic before being coated.
