CSC Services recently completed a specialist refurbishment project for Severn Trent Water, delivering improvements to a reservoir upstand to help restore asset performance and prevent future contamination risks.
As part of the scheme, our team raised and recast an access hatch to address a bacterial fail that had been identified during routine inspections. This required a full clean of the tank before applying suitable waterproof coating to protect the structure and support ongoing compliance.
To rebuild the upstand, we used Natcem 35 – a fast-setting, fast-curing repair mortar ideal for water industry environments where downtime needs to be kept to a minimum. Once the new upstand was in place, the access hatch was sealed with Fosroc Nitoseal. This durable sealant cures to a tough elastic rubber and fully complies with relevant Water Supply Regulations, ensuring the structure remains secure and watertight.
To further protect the asset, a Sika Decothane root-resistant waterproof membrane was applied. This high-performance coating guards against water ingress and carbonation, helping extend the life of the structure and reduce future maintenance requirements.
CSC Services has extensive experience delivering reservoir upstand refurbishments for water companies across the UK. Our operatives understand the unique challenges of working on critical clean water assets and are able to recommend the most effective protective coatings and repair solutions to maximise durability and cost efficiency.
