Protective water tank linings & coatings

Water Tank Lining and Repair

Even the toughest water tanks degrade over time, whether they’re steel, concrete or GRP. This often leads to cracks, leaks and eventually external contamination, leading to a multitude of problems.

We are specialist installers of a variety of surface protection linings and coatings for water and wastewater containment.

Whether you need a full tank refurbishment or a simple repair, give us a call on 01633 250652 or contact us below.

We use high-performance surface preparation is available to expose the stronger underlying tank surface prior to application, whilst maintaining its the structural integrity.

Surface repair

Cleaned surfaces are able to help us identify weaker, degraded areas susceptible to or already showing signs of breakdown. In such instances, a variety of substrate-specific sealants can be applied. 

High-performance surface protection

Strandek® work with a range of leading suppliers and our technicians are trained installers of a variety of high-performance systems:

Glass fibre: a tried and tested system comprised of glass fibre fragments saturated in polyester resin. Adherable to a variety of surfaces, this system hardens, forming a water-tight shield designed to last decades. It creates a smooth, waterproof surface that enables easy cleaning and discourages microbial growth. See more.

Polyurethane: solvent-free application offering greater elongation and flexibility that glass fibre, yet just as tough, making them perfect for structures susceptible to temperature-based expansion and contraction. See more.

Epoxy: solvent free, two component, high build, polyamine adduct cured epoxy paint which cures to a coating with good resistance to fresh water. See more.

Zinc: a single-component zinc-rich coating that acts as a “film galvanising system”. Comprised of 96% zinc and free of toxic components, this system is perfect for steel water tanks and offers performance comparable to hot-dip galvanising. See more.
