Life's too short to lose sleep over issues like containment. We get that!

Like you, we've also been awake at 3am, trying to figure out how to solve containment issues.

That's why we formed Formatank.

The Big Tank Guys

Formatank was born out of our own frustrations at finding cost-effective solutions for tank containment issues.

We realised that by lining existing tanks, we could save 80% of the cost of a new one. Over time, we've become known as 'The Big Tank Guys'.

Since 2012, we've added 2,500 years to the life of old tanks, saved businesses like yours over £6 million...and saved over 1,000 hours of lost sleep for asset managers(!)
