A Pipe Umbrella System consists of metal tubes placed on top of the micropile during its installation. The installed tubes expand into the surrounding soil, providing stability and preventing the hole from collapsing during excavation.

Additionally, they enhance the load-bearing capacity of the micropile by increasing the surface contact area with the soil, which helps distribute structural loads uniformly.

Rotation and percussion are applied to the crown through the drilling mouth. The shoe to which the the starting tube is welded, is left free. This prevents the pipe from rotating, thus reducing the torque requirements at the rotation head. The tubes are supplied in custom lengths, with standard or double-entry threads to streamline installation, and with an 8 mm guide entry to facilitate proper alignment during assembly.
