What is Tank Lining?

Tank lining is the application of a protective coating inside a tank to prevent corrosion and contamination. This durable layer extends the life of tanks used for water and liquid storage across various sectors.

What is Tank Relining?

Tank relining involves applying a new, high-performance internal lining to an existing tank. Using advanced coatings, relining restores tanks without replacement, making it the preferred solution for water and liquid storage needs.

What Types of Tanks Can Be Relined?

Relining suits tanks used for water and liquid storage, including those made from GRP, concrete and steel. COVAC’s relining services cover a wide range of tanks, such as bund tanks, rainwater harvesting tanks, attenuation tanks, cooling towers and more.

Can You Repair Holes in a Tank?

Yes, holes and damage in storage tanks are repairable through our tank lining process, ensuring long-lasting tank protection.

How Long Will the Tank Lining Last?

Our tank linings can last over 20 years, with COVAC providing a 10-year guarantee for dependable, durable tank protection.

Covac are one the best companies i have worksed with and their works are first class.

Yarwood, Lee
Covac undertook the task to 'reline' one of our hot water tanks, roughly 5m x 5m x 4.5m. This involved blast cleaning the tank, then applying epoxy lining to the tank.

The Covac team on site were fantastic, they dealt with issues that occurred efficiently & worked through the task quickly & professionally.

Parr, Ashley

John Meadows
Yet again Covac has proved their skill and expertise in meeting problems head on and resolving them within the agreed programme, despite a much larger scope of works! Thanks again to the whole team on site and in the office for making a very difficult task stress free - Highly regarded expert team and 110% recommended to anyone looking for tank refurbishment/relining works.
