GRP cold water storage tank Project in Edinburgh

Echo Square Services Ltd were asked to provide a solution to refurbish four GRP cold water storage tanks which were suffering from deterioration of the internal gel coat and corrosion of steel fittings.

We proposed that each tank be given long term protection by the application of a solvent free polyurethane coating.

The product employed was a solvent free DRINKING WATER POLYURETHANE (DWPU), which offers numerous economic, technical and environmental features and benefits, some of which are highlighted below: 

  • WRAS Approved 
  • Complete Solvent Free Technology 
  • High degree of flexibility @ > 35%, capable of accommodating structural movement compared with resin / epoxy / bitumastic coatings of <1.0% 
  • Superb adhesion to steel, concrete, GRP and many other substrates. 
  • High levels of impact and chemical resistance. 
  • Long life performance with minimal maintenance 
  • Easy clean, ceramic tile-like finish 
  • Excellent track record for applications such as drinking water tanks, cooling towers, reservoirs etc. 

Methodology

TANK 1
BEFORE – The tank internal surfaces were in very poor condition and there were signs of previous repairs.

PREPARATION – The tank internal surfaces were manually prepared to create a 75um surface profile to accept the DWPU coating.

REPAIR – Where the previous GRP repairs had started to delaminate, fiberglass repairs were completed to seal these gaps and holes in the hollow tie bars.

BASE COAT – A base coat of DWPU was applied to all internal surfaces at a nominal thickness of 500 micron.

TOP COAT – The above was repeated with a top coat of DWPU.

TANK 2
The above was repeated for the second tank

TANK 3
The above was repeated for the third tank

TANK 4
The above was repeated for the fourth tank

We manage a large residential block and recently reached out to Echo to quote to reline two water tanks that were failing. An absolute fantastic service all round. A quote was received within a day or so. Works were booked in and communication was excellent. We were really impressed with the engineers on the day. They communicated well on the day in terms of the plan of action. Once the work was complete, they ensured all areas were left clean and tidy. A follow up report post works was sent very soon after the works.We look forward to working with Echo again. If you need honest, reliable contractors who will get the job done and to a high a standard, don't hesitate to get in touch with them.Thank you.

I contacted Echo Square on behalf of a client of mine who urgently needed her Victorian underground Cistern re lined. The work was quoted for promptly and the work carried out to a high standard by the engineers who were courteous and friendly despite their long drive to site. My client was very impressed and so grateful to have her Cistern back in working order. I would highly recommend this company and will most definitely approach them again should I have another client with tank issues in the future. 5 star service!

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!
