Injection systems involve the injection of aqueous solutions into the ground to treat expansive, collapsible, and desiccated clay and railroad subgrade mud pockets. Hayward Baker has in-house designed and built rigs to perform these projects safely and efficiently.

Common Uses

  • Stabilize expansive soils
  • Cement embankment and levee slides
  • Stabilize railroad subgrades

Technical Details

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. This technique has been used to treat soils below planned and existing railways, roadways and buildings.

This technique is predominately provided by our Fort Worth, TX office and is available throughout North America.
