How long does water tank lining last?

Our Acothane DW tank lining can withstand a decade of constant use without requiring additional coats or upgrades to maintain optimal efficiency. Ordinary brands of water tank lining may only last for three to five years before needing a replacement. But clearly, Acothane DW is superior in quality and durability.

Here at COVAC, we ensure the fast and efficient installation of durable and effective lining that will protect your tank from damage for years to come. We offer a 10-year guarantee on our tank lining services across the UK and Scotland, which has helped us to build an enviable reputation over our excess of 25 years in business!

Why is water tank lining important?

Tank lining is essential to keeping your water tank in good condition to guarantee optimal efficiency. Without lining, bacteria, organic matter, and naturally occurring deterioration can considerably shorten the lifespan of your water tank, which could demand a total replacement of your tank. Replacement is costly, time-consuming, and will leave your building without a tank for some time. But lining is cost-efficient and far faster by comparison.

What is water tank lining made from?

Here at COVAC, we use a lining named Acothane DW, which is made of a highly hydrophobic substance, Polyurethane. Polyurethane disallows water ingress and prevents bacteria from reaching the surface of your water tank, which will prevent deterioration and irreparable damage.
