In addition to our ES 988 DWPU water tank reline service we also offer replacement fire sprinkler tank liners for structures that are not suitable for a polyurethane solution. These include water tanks manufactured by Franklin Hodge. Corrugated water tanks and various types of fire sprinkler water tanks also require a ‘sheet’ liner.

As with all solutions offered by Echo Square we only employ skilled and experienced consultants, engineers and technicians. This ensures that every tank reline is carried out to the highest standard of quality, durability and compliance.

What are the advantages of water tank relining?

There are numerous major benefits that can be achieved by relining your sites cold water storage tanks utilising our flexible polyurethane coating ES 988 DWPU they include:

Cost effective alternative to full water tank replacement works

Carrying out full water tank replacements can be very costly and time consuming therefore water tank relining can be a far more cost-effective alternative which ensures far less disruption is caused to a building’s services and occupants.

Less downtime

Tank relines can be carried out during “out of hours” working times & over weekends, often water tanks and process vessels are separated into two separate compartments, which ensure operatives are able to work on one compartment at a time, therefore keeping one compartment online at all times and ensuring the water system down services do not require isolating.

Fast curing times

Our solvent free polyurethane system ES 988 DWPU has very fast curing times which ensures in some cases full water tank relines can be carried out within just a couple of days, the fully refurbished water tank can then be cleaned, disinfected & refilled in line with ACoP L8 guidelines prior to being put back into service.

Coating flexibility

ES 988 DWPU once cured is extremely flexible with elongation properties of up to 35% ensuring it can accommodate all structural movements GRP, Steel & concrete structures naturally undergo when emptying and refilling, if a water tank is situated outside the coating is able to cope with the natural expansion and subtraction it undergoes due to temperature changes throughout the seasons.

WRAS approved

Our high performance polyurethane coating ES 988 DWPU is WRAS approved ensuring its perfect compatibility in conjunction with the internal relining of drinking water (potable) structures such as GRP & galvanised steel cold water storage tanks, cooling towers & process vessels.

Poor access

Often we find that existing water tanks have been constructed in areas which are difficult to access therefore resulting in situations where it is almost impossible to replace the failed structure, water tank relining is the ultimate solution for such circumstances as our tank relining system can be utilised without any requirement to disturb the current cold water storage tanks location. Once again ensuring disturbance and downtime is kept to an absolute minimum.

Water hygiene

Heavily corroded cold water storage tanks provide the perfect harbouring ground for harmful bacteria such as Legionella, corrosion issues are completely eradicated when a full tank reline is carried out as our coating once cured leaves a tile like finish therefore ensuring the tanks internal surfaces are compliant with ACoP L8 guidelines by no longer promoting the growth of harmful bacteria or providing an environment for corrosion to persist.

Future Maintenance

When cured ES 988 DWPU coating leaves a hard tile like finish which is also chemical resistant ensuring relined water tanks are far easier to inspect and disfinfect when required as part of all ACoP L8 compliant maintenance regimes.

Long-term Guarantee

Upon completion of all water tank relining projects our clients receive a full photographic completion report accompanied by our minimum 10 year guarantee covering against leaks, corrosion issues and osmosis blistering. Typically, new GRP cold water storage tank installations are only warrantied for 12 months upon completion.

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

Regardless of what material a cold water storage tank is constructed from the internal surfaces of all structures must be extensively prepared before our coating is applied. This process includes the removal of all loose material and contaminants using manual hand tools or utilising shot blasting equipment, once this process is completed the internal joints of the structure are strengthened to increase the water tanks structural integrity.

Application of ES 988 DWPU Solvent free polyurethane coating

Once the structures internal surfaces have been extensively prepared, all joints are initially stripe coated prior to applying the first coating of ES 988 DWPU (grey) across all internal surfaces the coating is then left to cure before then finally applying the second coating of ES 988 DWPU (blue) which is then left to cure. Finally, the structure is thoroughly inspected prior to being clean & disinfected in line with ACoP L8 guidelines before being filled and placed 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 suggest you have a leak as raised bacteria levels will likely be detected. 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 provide a water tank cleaning & disinfection service which can be carried out on an annual basis following on from carrying out a full tank reline.

Had a cold water tank in the loft full of dust, wasp and flies. Tanks were cleaned to a very good standard, considering the awkwardness of the job. Very happy with the service

We were carrying out plumbing works on a site in London where we discovered a badly leaking GRP water tank, the Echo Square Services team attended site as quickly as possible to repair the leak and reline the tank. We will definitely contact them next time we are faced with a similar issue - would highly recommend.

We had a heavily leaking metal water tank above our office which was leaking through our ceiling, Echo Square Services repaired the leak and relined the tank just two days after we made the enquiry!

Arrived very quickly when the crisis developed in the 100-year-old water tanks in this Grade 1 listed building; did what looks a highly professional job (re-lining two hard to get at tanks in the roof) all in one day - which involved working really late - and were careful to make no mess and cause no damage. So far, it looks a great job at a reasonable cost.

The team was very helpful, polite and knowledgeable. Glad to speak to people who know what they're doing. Won't hesitate to use them again in the future

Having used other companies in the past I can wholeheartedly say that our dealings with Nationwide Tank Relining have been a breath of fresh air. We have had tanks relined, water hygiene assessments and floor coatings. All work was carried out in a timely manner and the quality of work has each and every time been exemplary. My bosses are thrilled with my decision to switch to Nationwide Tank Relining and a tank that was relined 10 years ago by them still looks good as new internally, and the money we've saved from choosing the right supplier has proven to be a very smart business move. Highly recommended!
