Shoreline prides itself on the ability to provide our customers with the option of installing Manta Ray Earth Anchors for those projects where traditional ‘tie backs’ cannot be installed. Please read this information taken from the Manta Ray website on the installation and integrity these anchors provide:
"MANTA RAY® anchors, a patented labor and time saving device, are driven into the ground with no holes, no digging and no concrete. Unlike other anchoring systems, the MANTA RAY actually compacts the soil around itself providing a safe and environmentally sensitive installation. The anchors are driven with conventional hydraulic/pneumatic equipment that is readily available worldwide. Once driven to the proper depth, an upward pull on the anchor tendon rotates the MANTA RAY into a perpendicular "anchor lock" position in undisturbed soil. Proper holding capacity is measured by a gauge on the anchor locker. Each anchor is immediately proof loaded to the exact capacity required."
