Maintenance & Refurbishment



Liquitech is committed to getting the job done, especially when it comes to the maintenance of sprinkler tanks. Each job is important. From the start of the project right through to the finish, each team member will be there to assist and support.

You can count on us to be professional, punctual and efficient.



A typical maintenance or refurbishment regime may include some or even all of the following;

  • Draining down and cleaning of the tank floor and walls.

  • Where appropriate, repainting any damaged or failing paint finishes.

  • Repair of small holes or damaged panels in the tank shell.

  • Replacement of damaged or corroded internal pipework and fittings.

  • Installation of a waterproof liner. Where an existing liner has failed, we can install a replacement liner.

  • Repair or replacement of failing roofing materials. Where necessary, completely new roofs can be installed. 

  • Renewal of ancillaries such as immersion heaters, ball valves, suction lift foot valves, contents gauges, drain valves, pipework, insulation and lagging, access ladders etc.



For both industrial and potable use, Liquitech has a depth of experience applying Butyl liners to many types of water storage tanks. Most tanks are positioned externally at ground level, but we have lined many that are built below ground, within buildings, or even on structural steel towers.

Using Butyl, we have successfully lined water storage tanks up to 16.8m diameter; we have also installed tank liners up to 14m high, and in the case of rectangular tanks, up to 18m long.

Butyl liners offer high resistance to shrinkage and cracking. They are perfect for use as water tank liners because they can maintain flexibility and imperviousness at temperatures that are much beyond the extremes of the ambient weather in the UK. Butyl liners also provide excellent puncture resistance, frost resistance, and stability in direct sunshine.

Also an important consideration to note is that Butyl is 100% recyclable.


Tank Dismantling

Liquitech is also able to assist with the dismantling of storage tanks, where necessary. Bolted or welded tanks can be safely dismantled by us, leaving the materials on the job site, or as a licenced waste carrier, we can dispose of them for the customer.

The picture shows a sprinkler tank being dismantled. In order to allow our experts to safely work at ground level throughout, we are lowering the tank in a controlled manner utilising our certified hydraulic jacks.

Liquitech frequently completes turnkey projects, which include disconnecting the pipework, disassembling the tank, preparing the tank base for the new tank, installing the new tank, reconnecting the pipework, and adding ancillary components like trace heating, insulation, and lagging, among other things.
