A self drilling anchor system offers a robust solution for precarious ground conditions such as sand, gravel, silt, clays, and soft to medium fractured rock formations. At ONTON, our self-drilling anchor solutions are meticulously crafted to optimize installation, tailored precisely to the unique requirements of each project.
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 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.
