Water Tank Lining

Because a water tank is corroded or leaking, it doesn’t automatically mean an expensive tank replacement is required. In many cases professional repair and refurbishment work carried out on the existing tank is a cost-effective alternative.

Specialist Coatings (GB) Ltd provide a full water tank lining service or we can supply the water tank lining materials for use by competent persons. Click here for details.

Whether you need a water tank repair, water tank refurbishment, or a water tank coating, Specialist Coatings (GB) Ltd can help.

In-situ water tank refurbishment is far more practical and economical than tank replacement. Corrosion and scale formulation in a water tank can, if left untreated, weaken the structure of the vessel and create conditions for bacteria to form.

There is an efficient and cost effective solution of existing galvanized steel and fibreglass water tanks.

Corroded steel and worn or damaged fibreglass tanks used to store potable or process water can be easily repaired and refurbished using a smooth, easy to clean epoxy lining, which meets current regulations and extends the life of the tank, thus avoiding the need to replace existing tanks.

Our tank lining system has been developed for both potable and non-potable water storage. It provides long-term protection and extends the working life of the tank. The hard non-porous surface finish of our tank lining system inhibits contamination and the growth of bacteria, including Legionella and micro aquatic organisms.

Water tanks should have tight fitting lids complete with screened air vents and overflows, we at Specialist Coatings can now supply and if required fit lids for water tanks that conform with current water fittings standards, this is a service we offered as we realised that lids are not available for many types of tanks, especially the older water tanks.

A solvent-free non-tainting epoxy resin is used to line galvanised steel, fibreglass, concrete and carbon steel tanks, which conforms to BS 6920, is WRAS, FDA and/or NSF approved, and manufactured to BS EN ISO 9002. Its application is ideal for use in confined areas where access is limited or where the production of dust and fumes would be problematic.
