COLD WATER TANK UPGRADE - SEVERN VALLEY This pair of steel water tanks in the Severn Valley were leaking and corroding badly internally. It was an easy decision to upgrade these tanks by applying a fibreglass lining system to the internal walls and floor. We brought in a local scaffolder to erect platforms up to the tanks for access and egress, enabling us to work safely throughout the repair and refurbishment. After the internal surfaces were scraped relatively clean we keyed the surfaces by grit blasting using Hodge Clemco JBlast Supa blasting as the media. After the preparatory gritblasting 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.
