COLD WATER TANK UPGRADE - SEVERN VALLEY These cold water tanks in the Severn Valley were leaking and corroding badly. After non destructive testing/ NDT we restructured the internal surfaces with our fibreglass lining system to give them a new lease of life. We brought in a local scaffolder to erect platforms up to the tanks for safe access and egress, enabling us to work safely throughout the refurbishment. Once the tanks were washed and cleaned, the surfaces were sand blasted with Hodge Clemco JBlast Supa blasting media. After sandblasting and priming, layers of woven fibreglass and chopped strand fibreglass matting were applied to the surfaces and wetted out with Lloyds approved isophthalic polyester resin. The cured fibreglass lining was completely sealed with an isophthalic gel topcoat protecting the surfaces for at least the next 25 years.
