Applications of Self-Drilling Anchors
Mar 08, 2019
Slope stabilization

Self-Drilling Anchors are used to stabilize unstable rock/soil formations. The unconsolidated or weathered ground conditions favor the SDA technique for a fast and simple method of installation compared to the traditional methods.

Foundations with micropiles

SDA micropiles can be defined as drilled piles, composed of injected grout with the anchor rod as steel reinforcement. They can be installed in sites with limited space using light drilling equipment, can be installed into most ground conditions including rock and are suitable for tension and compression loads. The big advantage is the combined drilling and grouting making high piling outputs possible.


Self drilling anchors are the most economical solution for the reinforcement of the tunnel circumference and advanced roof support for tunnel excavation in overburdened and soft fractured rock conditions.
