Injection systems involve injecting aqueous solutions into the ground to treat expansive, collapsible, and desiccated clay and railroad subgrade mud pockets.
Process
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 treating expansive soils.
