Tank Lining Service

Tank repair, lining and sealing upgrades with GRP

Existing tanks deteriorate. With exposure to chemicals, cycling and different temperatures, your tanks need to be protected to help you avoid problems.

Refurbishment as little as 20%
of the cost of replacement

If your tanks are already showing signs of wear, you don't have to replace them. A GRP lining refurbishment can cost as little as 20% of the cost of a tank replacement.

Durable tank linings and coatings for any conditions

A GRP lining is economical and hard-wearing – and can be customised using a variety of resins and additives to withstand almost any conditions and contents.

Whether you need to repair or line water tanks, chemical storage tanks, effluent tanks or even liquor tanks, we'll individually mix the right fibreglass tank lining for your needs.

Avoid the cost of a new tank

If you act fast, you can avoid replacing your tank. Thanks to our range of products – including epoxy compounds, polyester pastes and glass reinforced resins – we can fix most problems quickly.

We're experts at surface preparation, whatever your surface problem or structure of the base material, we can prepare it for the repairs you need.

Best of all, we'll normally have tank restoration completed within the week – and it will remain impact resistant and easy to clean for many years to come.

Tank lining repair guide

Industrial tanks house a variety of liquids from chemicals to effluent – but because most of them are constructed from steel and concrete, they are also subject to rust, corrosion and erosion.

Over time, a tank's original structure can deteriorate, causing problems such as cracks, leaks and failed joints – which could lead to dangerous spills...

That's where a tank lining comes in. A GRP lining is economical, versatile and hard-wearing – effectively creating a tank within a tank.

It provides a stable, chemical- and impact-resistant structure within your existing tank, extending its useful life by more than 20 years.

By choosing a GRP lining instead of replacing your damaged tank, you can also save up to 80% on your costs.

What kinds of tanks can be repaired?

Fibreglass tank linings from Sui Generis can increase the longevity of tanks constructed from any material – including concrete, steel and polypropylene.

Our industrial linings can contain most kinds of liquids, from toxic or corrosive chemicals right through to aviation fuel and alcohol. Some of the tanks we can line for you include:

  • Sectional water tanks
  • Process water tanks
  • Portable water tanks
  • Liquor tanks
  • Effluent tanks
  • Water treatment tanks
  • Sprinkler tanks
  • Diesel tanks
  • Fuel oil tanks
  • Gas oil tanks
  • Fertilizer tanks
  • Chemical storage tanks
  • Offshore applications.

Why choose fibreglass tank repair?

Because its tough, hard-wearing and handles normal structural movement well – which is especially important for concrete structures.

A GRP tank lining is also thicker than an ordinary epoxy coating. Where the latter is only a 0.5mm barrier, a fibreglass tank lining is between 2mm and 6mm thick.

It can also be used to line over cracks, corrosion and thinning tank walls – giving your tank a new lease on life and you lasting peace of mind.

Moreover, each lining is individually mixed using resins and additives to meet the needs of your tank and what its contents.

Are there other benefits to GRP tank linings?

Yes. A GRP lining for your tank will also be:

  • Corrosion Proof
  • Chemical resistant
  • Leak free
  • Impact resistant
  • Flexible
