Repair & Refurbishment

Leak diagnosis, panel and seal replacement, structural repair. Any brand of bolted tank, whoever put it up.

What we fix

Repairs, not replacements

A tank with sound steel and tired seals is a seal job. Being told to replace the whole thing is usually a sign you are talking to someone who only sells new ones.

  1. 01

    Leak diagnosis

    Finding where a tank actually leaks, which is very rarely where the water shows up on the outside.

  2. 02

    Panel replacement

    Damaged or corroded panels out, sound ones in, and the seals seated properly on the way back together.

  3. 03

    Seals and gaskets

    The usual culprit, and the cheapest thing on this list to put right if somebody looks at it early enough.

  4. 04

    Structural repair

    Shell, roof steel and rafters where the structure itself has taken damage rather than just leaked.

  5. 05

    Refurbishment

    Older tanks brought back into service instead of replaced, where the shell is still worth the work.

  6. 06

    Whoever built it

    We hold no brand's warranty and defend nobody's install. A good share of this work is other crews' tanks that need putting right.

How it goes

Diagnosis first, then steel

Knowing precisely where an install goes wrong is why ours hold. It is also why we are quick at finding the fault in someone else's.

Finding the fault

Bolted tanks fail in a small number of well known places, and the seams and seals account for most of it. Water tracks along a floor and appears somewhere else entirely, so the wet patch outside is the last place worth looking.

Back into service

New panels, new seals, or a new liner over a shell that is still perfectly good. A tank that has been put right properly should not be distinguishable from one that never went wrong.

Where they go

Five sectors, one set of hands

What changes between a fire water tank and an effluent tank is the liner, the fittings and the compliance around it. The steel gets the same treatment either way.
