Protective water tank linings & coatings

Cooling Tower & Tank Lining and Repair

Exposed to constant moisture and damp, cooling towers and water tanks degrade over time. Whether they’re steel or concrete, microscopic damage can lead to cracks, leaks and eventually external contamination, leading to a multitude of problems.

Strandek® GRP Systems 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:

GRP lining: glass re-inforced polyster composites are tried and tested lining systems comprised of glass fibre fragments saturated in polyester resin. Adherable to a variety of surfaces, this system quickly hardens, forming a water-tight shield designed to last decades. They create a smooth, waterproof surface that enables easy cleaning and discourages microbial growth. Lifetimes from 10 - 50 years depending on application.

Polyurethane: solvent-free polymer-based 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.

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

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


We utilise WRAS (Water Regulations Advisory Scheme)-, BS6920:2014-compliant ingredients, as well as:

High build capability in a single coat 

Excellent corrosion resistance

Versatile application, brush/ roller or spray 

Potable water approved

Water tank benefits

Cost-effective solution: avoids tank replacement

Reduced downtime of production areas 

Long-term corrosion protection

Other applications

As well as drinking water tanks and fittings, we also provide surface protection for pump casings, internal & external pipes as well as wastewater & effluent systems.
