DrainsAid have recently completed a small but innovative project for our valued client Anglian Water. The works were to seal and spray an external tank with an impermeable coating. Following preparation of the surfaces and repairing multiple cracks with Ergelit 10SD,  the tank was then sprayed with Ergelit KBF40 using the Hermes M coating spray unit. The material was left to cure for a week then a successful drop test was undertaken, and the tank put straight back into service.
