Glasgow Underground. Koster Injection Systems.
Koster Aquatecnic Ltd
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.For more information or for advice on a similar project, please contact the Koster Technical team on technical@kosteruk.com.

Restoration of the foundations at a wind energy plant
Koster Aquatecnic Ltd
Concrete foundations of a wind energy plant:
Due to the influences of the weather over the years, the following damages were noticed:
•Cracks due to movement
•Moisture into the structure
•Spalling of the concrete
•Corrosion of the reinforcement
•Flaking paint
The first step in the restoration of the foundation was pressure injecting the cracks - through which an elastic closure of the cracks was realized. The total surface was strengthened with a unique sillicate liquid.
A waterproof sloped layer was installed; finally, the moving joint between the foundations and the steel tower of the wind energy plant was sealed elastically.
