Quex Park Estate: Water Tank Lining Project

Quex Park and Museum is a historical house and major tourist attraction built in the late 1800s near Birchington in Kent.

The Client

The estate manager commissioned Specialist Coatings to restore and repair a significantly corroded and ageing galvanised steel cold water tank.


  • The tank was located in a small attic area in a roof void.
  • Due to the limited space and condition of the tank, manual preparation was the only option.
  • During preparation, the heavily scaled, corroded and rusted tank revealed significant damage to its walls.
  • Substantial holes and steel loss around the inlet ball valve were discovered in two of the tank walls, measuring 650mm x 50mm and 200mm x 50mm.
  • These were the worst holes we have ever found in galvanised steel to date and left untreated could have resulted in extensive damage to the property.

Under normal circumstances, this water tank would have been condemned, which would have caused major expense and inconvenience. However, our water tank repair system enabled us to thoroughly repair the holes and coat the entire water tank, making it completely water-tight again.

Although repairing the holes extended our schedule by an extra day, our highly skilled technicians and proven tank lining system dealt with unforeseen onsite issues efficiently and with minimum disruption to our clients. As with all confined space projects, one person remained outside the tank at all times to give assistance should it be required.

The Results

There were some additional works required to repair the extensive holes in the tank walls. The refurbishment and repair works completed on this cold water tank will extend the practical working life of the tank for a good many years.
