Water Tank

Water tank lining is essential to keep your water retaining structure protected from corrosion and erosion that can lead to bacteria growth. If your water tank coating does not properly protect the substrate of your tank you could end up with significant damage and an increased chance of bacteria like legionella harbouring in your structure.


Steel Tank

Steel tank lining ensures that the steel substrate of your tank remains protected from corrosion. Corrosion can leave the essential nutrients for bacteria such as legionella, so it is vital that your steel tank coating is resistant to the growth of bacteria.


Concrete Tank

Concrete tank lining is essential in concrete liquid retaining structures, as they can be subject to erosion and deterioration if they are not sufficiently protected. At Covac we offer a fantastic concrete tank relining service so you can ensure that your concrete tank is resistant to erosion.


GRP Tank

GRP Tank Lining is vital in plastic tanks as without full protection the material can become cracked and air-filled cavities can be present which leaves conditions for bacteria to multiply. Our exceptional GRP tank lining service can prevent this from happening in future by using our COVAC coating system.

Bund Lining

In bunded tanks, it is vital that a bund lining has been applied to provide your tank with sufficient protection from chemical attacks and to resist erosion. As part of our excellent bunded tank lining service, we apply an Athocane DW coating to do the above and more.

Cooling Tower Lining

Cooling tower lining is vital in cooling towers to prevent corrosion, delimitation and degrading mastic. Without a protective coating, your cooling towers can be prone to sludge and scale which can lead to the growth of bacteria and also result in contamination of stored water.

Effluent Tank

Effluent tank lining prevents and resists chemical attacks that can lead to the deterioration and breakdown of materials in your effluent tank. Our effluent tank coating service ensures that your tank has full protection from chemical attacks by using or chemical resistant Acothane DW coating.

What are the cost benefits of lining tanks?

The cost benefits of lining tanks are plentiful, especially when considered long-term. Although water tank lining is an investment initially, the damage it will save your tank over the years will allow it to more than pay for itself. Restoring a damaged tank without lining is a far greater and more expensive job than upgrading the tank lining once its lifespan is up. Furthermore, water tanks with no lining are more susceptible to irreparable damage that requires a replacement, which will be far more costly than installing water tank lining.

Does COVAC provide any warranties on tank lining?

Yes! We offer a 10-year warranty on all tank lining we install in any type of tank in any condition. Please don’t hesitate to contact us to find out more about our water tank lining warranties!

What types of lining do COVAC offer?

Here at COVAC, we offer tank lining for all types of water tanks, from potable and drinking water tanks to galvanised steel and concrete. We use our specially-designed Acothane DW to coat each tank we work on, which tightly adheres to and protects the surface of your water tank for years of constant use without cracking, splitting, or sustaining damage from organisms and bacteria.
