Earth Retention Systems

Manta Ray Earth & Rock Anchors

MANTA RAYs are driven into the ground, not augured or torqued, nor is a hole dug or drilled. There is "no disturbance" or "displacement" of soil. Unlike other anchoring systems, MANTA RAY actually compacts the soil around itself - a clean, safe and simple operation.

The anchors are driven with conventional hydraulic/pneumatic equipment that is readily available worldwide. Once driven to the proper depth, the rod/tendon attached to the anchor is pulled to rotate the anchor into undisturbed soil - like a toggle bolt. This is called "ANCHOR LOCKING" the anchor (using the MANTA RAY Anchor Locker). The anchor is pulled upon to reach the holding capacity required which is measured by a gauge on the "ANCHOR LOCKER." Each anchor is immediately proof loaded to the exact capacity required. No other system offers this feature. Learn More >>
