Micropiles

 One of the faster growing segments for Forasol’s business, micropiles are small diameter piles which employ a steel pipe or tube, and are installed using various drilling techniques. They are then grouted in place to achieve lateral, tensile and compression load-bearing capacity and are an ideal underpinning alternative to large diameter piles.

 Micropiles are installed much like tiebacks or soil nails, using rotary or percussion drilling rigs. Because of their smaller size, a wide variety of drilling techniques can be employed more economically, which makes their use so attractive: flight auger, tri-cone, percussion rod, down-the-hole-hammer, casing with auger, hollow grouting drill, percussion rod etc.

They are also ideal where there is limited or difficult access or work space, like inside buildings for seismic reinforcement. Micropiles are finding ever greater acceptance with engineers and architects who are replacing traditional piles with micropiles - to the benefit of our clients.
