The Ashford Common water treatment plant, located in Surrey, is one of the largest water treatment plants in Europe. With a maximum output of approximately 7,870 litres of water per second, Ashford Common provides around a third of London’s water supply.

Our long-standing client Thames Water have appointed us to carry out the liquid roofing overlay to the main pump house, offices, and various ancillary buildings on the site. We’ll be installing Proteus Pro-Cold to cover the 10,000m2 of roof, which is a high-performance, seamless, and cold-applied waterproofing membrane that is suitable for use in all climates. We will also be installing full scaffold access with edge protection.

The £1.2m project is due to commence mid-July and is scheduled for 22 weeks.
