Injection systems involve the injection of aqueous solutions into the ground to treat expansive, collapsible, and desiccated clay and railroad subgrade mud pockets.

Common uses

Treat soils below planned and existing railways, roadways and buildings
Stabilize expansive soil
Cement embankment and levee slides
Stabilize railroad subgrades

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 treatment of expansive soils.
