Self-Drill Anchors

Soil nailing is an efficient construction technique that serves as a means of reinforcing soil to make it more stable. Essentially, soil nailing is used for deep excavations; strengthen existing retaining walls, instable slopes and more, with the sole purpose increasing stability.

DESCRIPTION:

Hollow bars are driven and grout is injected through the hollow bar simultaneously during the drilling.

This method is faster than the grouted nailing and it exhibits more corrosion protection than driven nail.

Advantages:

  1. Particularly suitable for difficult ground condition also in collapsible strata.
  2. A high rate of installation since drilling, placing and grouting can be performed in a single operation.
  3. Self-drilling system eliminates the requirement for a cased borehole.
