Waste Research and Reclamation Co. Inc. (Eau Claire, Wis), several years ago began looking for protective coatings to apply to concrete secondary containment surfaces. Although coatings for concrete floors have been available for some time, application of floor sealers and thin-film coatings were unsuccessful in secondary containment applications. About three years ago, the company discovered a copolymer-based industrial flooring material designed specifically to resist attack from a broad variety of chemicals, including highly corrosive acids and bases. Initial evaluations of the flooring's performance are quite positive. It has proved impermeable to spilled materials and stands up well in high-traffic areas. Odorless, non-porous Overkote[reg sign] materials are available in various formulations, depending on the situation. One version, a heavy-duty floor topping designed for severe chemical service, is used at the Waste Research and Reclamation facility to protect against sulfuric acid spills. Another version was installed in the chemical loading and unloading areas, and in places where drummed wastes are stored. Overkote[reg sign] MC is designed to resist halogenated solvents. In containment applications, it provides a useful immersion life of up to three weeks, compared to less than two hours for some other systems. This material is used to protect areas beneath solvent storage tanks, pumps and piping. Still another format is a composite material designed for use on walls, and joints between walls and floors.
