Contract Date: 2017
Project Value: £50K
Building / Structure / Area: Storm water overflow tank
Client: United Utilities
Main Contractor: GCA
Main Products / Systems used: Sika 201 Polyurethane water stop
Project Summary: A storm water overflow tank was constructed using pre-cast concrete rings sunk to a depth of 30m. The base slab was then cast out of reinforced concrete. Unfortunately, it was noted soon after there was significant ground eater infiltration that required water stopping prior to being put into service. CTL proposed the use of Sika water reactive polyurethane systems injected via a complex series of injection points using high pressured injection techniques to prevent future water ingress.
