Injection systems involve the injection of aqueous solutions into the ground to treat expansive, collapsible, and desiccated clay and railroad subgrade mud pockets.
The composition of the aqueous solution depends on the application. Injection units advance injection pipes into the treatment zone. An aqueous solution of water, lime slurry, cement slurry, or potassium chloride is injected to reduce shrink/swell potential for treatment of expansive soils.
Keller can provide comprehensive solutions that combine sealing injection with real-time monitoring of reinforced structures. The company has a wide range of plant and equipment allowing us to work under many different conditions.
