Hollow Bar Micropiles

Hollow bar micropiles are installed in difficult geological conditions to build high capacity piles or anchors. A continuously threaded steel bar is drilled into the ground with a sacrificial bit. Flushing water or cement is used to evacuate cuttings from the hole during drilling. Once the target depth is achieved a finish cement is pumped down the centre of the hollow bar and forced into the surrounding formation and up hole to fully encapsulate the hollow bar.

​

Hollow bars can achieve very high tensile and compressive loads and be installed with compact equipment which makes them suitable for any site and any geological condition encountered.

​

Our staff are able to assist with design, planning, installation and testing of hollow bar micropile systems for your project.
