We are interested in all forms of drilling related construction, including but not limited to excavation support systems, soldier pile retaining walls, landslide stabilization, dewatering well systems, Shotcrete retaining walls, soil nail walls, secant walls, elevator jackshafts, underpinning and deep foundations for towers, transmission line foundations, pole structures and caissons. We specialize in difficult access situations and have the equipment and experience to drill almost any shaft.

  • Micropiles

    Drilled micropiles used for underpinning typically consist of a core steel element surrounded by a neat cement grout mixture with diameters of 60 to 200mm.  Installation of micropiles can be ideal in areas where pile installation has low headroom or area restrictions.  Micropiles can be achieved using a variety of techniques such as drilling, impact driving, jacking, vibrating or screwing equipment.  Micropiles are a viable, practical solution to high-capacity structural load transfer to more stable, competent subsurface strata. 

    Micropile Advantages:

    • Micropile drilling methods generate minimal disturbance to the environment or vibration to adjacent structures.
    • Excellent underpinning solution.
  • CIDH Piles

    Also called caissons, drilled shafts, drilled piers, Cast-in-drilled-hole piles (CIDH piles) or Cast-in-Situ piles. Rotary boring techniques offer larger diameter piles than any other piling method and permit pile construction through particularly dense or hard strata.  CIDH piles are a deep foundation support that is constructed by placing fresh concrete and reinforcing steel into a drilled shaft. These reinforced concrete piles are cast in holes of predetermined diameters and depths drilled through soil and rock to the desired bearing stratum.

    CIDH Benefits:

    • Able to support high, concentrated loads.
    • Popular slide prevention application.
    • Versatile, reliable and economical solution.
