Jet grouting is a specialized process that produces in-situ mixing of soil with a stabilizer (usually neat cement grout).

Common Uses

  • Structural Foundation Support
  • Support of Excavation
  • Base Plugs for Groundwater Control
  • Slope Stabilization
  • Structural Underpinning
  • Seepage Barrier / Cut-off Walls
  • In-situ Stabilization
  • Environmental Remediation
  • Soil Mixing

Drilling is performed using rotary drilling techniques and an external water flush with special drill rods and bits.

After drilling to the required depth, the jet grout drill rods are rotated and raised to the ground surface at controlled rates, while injecting cement grout at a high pressure, forming a soil-cement column. When placed in engineered configurations, the columns can be constructed to provide effective treatment of large masses of soils.

Advantages to the jet grouting method include higher compressive soil strengths in comparison to other soil improvement methods, more uniform soil treatment, the capability to improve isolated soil areas, and definitive quantity and scheduling. Key principals of Bencor have been engaged in jet grouting production and technology since its origins in Italy. Many jet grouting techniques and specialized equipment improvements that have become industry standards were conceived and advanced by these individuals.
