Self-drilling anchors

These anchors redefine conventional bolting methods by utilizing a streamlined technique. With a sacrificial drill bit and a hollow rod, they penetrate collapsing soil or loose rock. Post-drilling, cementitious grout or resin is injected into the hollow rod and surrounding cavity, elevating self-drilling anchors to a pinnacle of productivity.

Comprising elements

Comprising elements like a hexagonal nut, bearing plate, extension couplings (if involving multiple anchor rod sections), hollow anchor rod(s), and a sacrificial drill bit, our self-drilling anchor bolts guarantee structural integrity and stability in challenging environments.

The applications of ONTON’s self drilling anchor system span across critical sectors:

  • Slope Stabilization
    Unstable rock and soil formations find stability through our self-drilling anchors. The technique’s efficiency in unconsolidated or weathered ground conditions surpasses traditional methods, ensuring swift and uncomplicated installation.
  • Foundations with Micropiles
    Our SDA micropiles, crafted as drilled piles with injected grout and steel reinforcement via anchor rods, suit limited-space sites. Capable of installation in diverse ground conditions, including rock, they accommodate tension and compression loads efficiently, enabling high piling outputs.
  • Tunneling
    For tunnel excavation in overburdened and soft fractured rock conditions, ONTON’s self-drilling anchor system emerge as the most economical solution. They reinforce the tunnel circumference and provide advanced roof support, ensuring safety and stability.
