Lining, Coating and Acid Proofing

Reservoirs and tanks are susceptible to corrosion, they benefit from a liner or special coating. The choice of liner will depend on what material the tank is composed of, where it is located, dilapidated condition and ultimately cost.

The material liner selected should create an impermeable barrier, fully adhere to the substrate, and seal all the gaps. In addition, manufacturers and distributors of any water treatment product, including liners, must comply with Potable Water System Components and Health Effects. Where drinking water supplies are involved, regulative compliance standards have been developed by scientists, industry experts, and industry stakeholders, and implemented by Government agencies. Established criteria for water system components, include;

  • protective barrier materials (cements, paints, coatings);

  • joining and sealing materials (hydrostatic seals, adhesives, lubricants);

  • mechanical devices (isolator valves, water meters and filters);

  • pipes and related items (pipe, hose, fittings);

  • plumbing devices (faucets, drinking fountains);

  • process media (filter media, ion exchange resins); and

  • non-metallic potable water materials.

Traditional paint systems consisted of three coats of epoxy 3–5 mil for a total of 12 mil of protection. However, technology is evolving rapidly and now, a one-coat system may vary between 6mm and 30mm resulting in a substantial reduction of labour costs as well as the diminished possibility of inner coat adhesion failure.
