Multinational Consumer Goods Company Chooses Stonhard for Containment Tank Linings Solution

Concrete Containment Tank Faces Corrosive Threats

A multinational consumer goods company in Northwest England constructed a containment tank to store hypochlorous acid. The concrete structure required protection from corrosive chemical exposure and potential spills during regular operations or in the event of failure. In such aggressive environments, linings must not only withstand harsh chemicals but also endure the physical stresses of the application, including static cracks and thermal shock.

Stonchem lining systems provide chemical-resistant protection for containment tanks.

This containment area features a smooth, corrosion-resistant finish designed to withstand hypochlorous acid exposure and maintain compliance with safety and environmental standards.

High-Performance Lining System Protects Containment Tank from Corrosive Chemical Exposure

Stonhard recommended and installed a highly cross-linked vinyl ester lining system to meet the site’s critical requirements. Stonchem 856 was applied at 2.5 mm to the bund floor, while Stonchem 855 was used on the tank walls. Stonchem primer and Stonclad UR polyurethane system were specified for fillets and coving.

The resin, engineering fabric, mortar coat, and mineral composite topcoat sequencing provides a smooth, chemical barrier that is resistant to small static cracks and moderate thermal shock. The system offers a seamless, heavy-duty chemical barrier with excellent resistance to a wide range of aggressive substances, including organic and inorganic acids, alkalis, and solvents.

The project was completed in a two-week period that minimized downtime, providing the client with a durable, compliant solution for the safe storage and handling of hypochlorous acid.
