Glasgow Underground. Koster Injection Systems.

Following successful works for the London Underground, Koster were asked to design waterproofing systems for use inside live tunnels for the Glasgow Underground.

Following close analysis of the structure, surrounding ground and constant use, a bespoke design was settled upon which involved an area injection system as the main form of waterproofing protection.

Koster Injection Gel G4, an acrylic injection material was selected, mainly due to the fact that it has an extremely low viscosity and will not contaminate ground water or soils.

When injected in a grid pattern across the substrate (through pre -installed injection ports), it will travel through the pores of the brickwork and "Gel" forming a permanently elastic mass capable of holding back the pressure of water behind the structure.

The Koster Technical team become heavily involved in these types of projects, working carefully with the design team and contractors ensuring a successful project completion.
