Tiebacks/Mini-piles

TIEBACKS / MINI PILES 
<CLICK TO SEE OUR AD>


    Tieback Anchors can replace internal braces to provide an excavation free of obstructions.  Tiebacks can be installed in virtually any ground condition using rotary, percussion or down-the-hole hammer tooling.  Tiebacks are constructed by drilling a small diameter shaft into the ground behind the sheeting system.  Steel tendons are inserted into the shaft.  Grout is pumped into the shaft to anchor the tendons as the drill casing is retracted.  Hydraulic jacks lock-off the tieback to the sheeting system.  Multiple levels of tiebacks allow for very deep excavations.






 
 
    





    Mini-Piles can replace conventional piles where there is limited or difficult access or work space, like inside buildings.  Mini-piles or micro-piles are installed much like tiebacks, using rotary or percussion drilling rigs.
