Stonhard Provides Hard-Wearing Solution for UK Water Treatment Plant

In the United Kingdom, Avonmouth-based Wessex Water serves 2.9 million customers across southwest England. Corrosive elements in the onsite waste had attacked the concrete floor surface, leaving it pitted and uneven. A subsequent overlayment installed to combat the problem had also failed, leaving the floor in need of a proven, long-lasting solution.

Stonhard visited the Wessex Water site over a period of 18 months to test the existing finishes and structural slab. Stonhard proposed the removal of all existing finishes back down to the structural slab and the installation of a new chemical-resistant flooring system. The project included a new concrete overlay pitched to slope, new surface drainage, and a durable floor finish that would withstand movement from the facility’s 25-ton mechanical loader.

Stonhard installed polyurethane Stonclad UT, a high-impact floor that exhibits excellent abrasion, thermal shock and cycling, and chemical-resistant characteristics. The system was further reinforced with a layer of Stonchem 601, a highly cross-linked novolac epoxy lining system, to enhance its chemical-resistant properties.

“Kemtile [a division of Stonhard] brought great expertise to the table from day one, dealing with a significant level of deterioration and providing immediate support, as well as supplying the final flooring fix over the 18 months that we worked together," Dan Owen, Project Engineer of GENco/Wessex Water Enterprises, said. "I commend them on seamless delivery with minimum disruption to the rest of the plant which remained in operation throughout.”
