How are water tanks relined?
Every tank relining project is unique, often the most appropriate relining process is dependent on the structures size, how its constructed, the water tanks internal condition and what substrate our operatives would be preparing and applying our coating to i.e. if the water tank is concrete, galvanised steel, or glass reinforced plastic (GRP)
Preparation is essential
Our team thoroughly prepares every cold water storage tank, regardless of its material, before we apply our coating. We start by removing all loose material and contaminants using manual hand tools or shot blasting equipment. Once the surfaces are clean, we reinforce the internal joints to strengthen the tank and improve its overall structural integrity.
Application of ES 988 DWPU Solvent free polyurethane coating
After thoroughly preparing the structure’s internal surfaces, we stripe coat all joints before applying the first layer of ES 988 DWPU (grey) across all internal surfaces. We then allow the coating to cure before applying the second layer of ES 988 DWPU (blue), which also undergoes a full curing process. Once both coatings have cured, our team conducts a thorough inspection, followed by cleaning and disinfection in line with ACoP L8 guidelines. Finally, we refill the tank and bring it back online.
Risk Factors & Signs of Tank Damage
Liquid storage tanks are subject to pressure and corrosion from water, fuel or other liquids contained within. The sheer weight of the liquid puts pressure on the joints, walls and base of the structure. Over time wear and tear occurs leading to corrosion which causes contamination of the water. In addition leaks can develop which allows further contamination due to the ability of foreign material and bacteria to enter the tank through the leak point.
In-house water testing may indicate a leak if it detects elevated bacteria levels. It is important to ensure you have procedures in place to monitor and control the risks of Legionella bacteria. Furthermore if the leak is significant and depending on the location of the tank there may be water damage to nearby structures and equipment. This can happen relatively quickly if the bund is in poor condition or if there is no bund present. Regular visual inspections will help you to spot problems early and enable low-cost repairs. We offer a full bund lining and repair service to ensure your water storage tank system operates at optimal performance and is fully compliant.
Our engineers can also service associated pipework and our manufacturing facility enables us to provide bespoke solutions in a timely and cost-effective manner. Our full water tank reline and water tank repair service provides a long-term solution at a much lower cost than full water tank replacement. We also offer a water tank cleaning and disinfection service, which we can carry out annually after completing a full tank reline.
