SOIL IMPROVEMENT

At Henry Drilling, we provide advanced soil mixing solutions engineered to improve ground stability and create structural barriers. Utilizing specialized high-torque machinery, our single axis and triple axis auger mixing methods efficiently blend in-situ soil with grout or bentonite to build foundation elements, install high-capacity shoring, or create reliable water cut-offs for deep excavations. Explore our specific soil mixing capabilities below to determine the ideal approach for your site's ground conditions.

  • With single axis soil mixing, the soil is mixed with grout injected through the drill string. This process creates a grout soil mix that is typically in the range of 1-5mpa.

    Applications and Equipment Capabilities

    This specific installation method can be used for:

    • Foundation piles

    • Shoring

    HFDI uses this method when mass mixing or having to penetrate difficult soil conditions. To perform this work, we utilize high torque drilling machines, such as our Bauer BG40’s.

  • The triple axis auger mixing method consists of three soil mixing tools that overlap, creating a continuous wall three piles at a time.

    During the installation process, grout and bentonite are injected through the center stem of the augers as the tools are advanced into the soil, producing a consistent soil and grout mixture.

    Applications and Advantages

    This installation method is a cost-effective way to:

    • Install shoring

    • Build foundation elements

    • Create a water cut-off for deep excavations
