Do you own or manage premises with a hot and cold water system?

You’ll be surprised at the horrors we discover in some cold-water storage tanks.

You see, because the mains supplies your cold water, in time your tank will inevitably accumulate debris, sludge and silt. It makes the water look dirty.

What’s more, it’s not uncommon to discover contamination from bird and pigeon poo or even dead, decomposing rodents floating about. It doesn’t bear thinking about right?

Would you drink this water?

Is your cold-water storage tank leaking, corroding or posing an increased legionella risk?

Whatever your situation, our expert team of professional fitters can provide you with tank re-lining of your water storage facilities to ensure they are hygienic, fit for purpose and designed to minimise the risk of  legionella growth.

Just because your tank is corroded or leaking, it doesn’t automatically mean a replacement is required.

In a number of cases, professional repair and re-lining work is a cost-effective alternative that also avoids the need to dispose of your existing tank.  For example:


For cold water storage tanks, we favour  the application of solvent free polyurethane coatings 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 and an easy clean, ceramic tile-like finish
  • Excellent track record for applications such as drinking water tanks, cooling towers, reservoirs etc.

In addition to re-lining your cold water storage tank, we can also ensure it complies with the Water Supply (Water Fittings) Regulations 1999 by:

  • Installing insulation to the tank and associated pipework
  • Installing a new lid where required
  • Installing an insect screen to the warning and overflow pipework
  • Re-plumbing to ensure good water flow through the tank

Hi Con

Just wanted to say thank you for your teams hard work and how much our staff appreciated how the team worked and how they communicated with them about the process of relining the tanks and what they were doing.

Everything went smoothly and staff and residents said how pleasant your team were.
