How it Works:

Our Terra-Lock Anchors have been designed to be used as a complete stabilization system alongside our Terra-Lock and Liner-Lock plates. To see the full install steps, download the Technical Data Pack below.

Download the Technical Data Pack
1. Insert the drive rod into the Terra-Lock anchor and push the anchor into the ground
2. Place the Gripple Gas-Powered Driver onto the end of the drive rod and drive the anchor into the ground. If installing into harder soils or more challenging applications, the Terra-Lock Anchors can be installed using heavier machinery.
3. Pull the drive rod out of the ground. Use the JackJaw tool if required.
4. Place the JackJaw tool on top of the Terra-Lock plate and insert the wire rope into the jaws. Push down on the JackJaw handle to pull the wire upwards and lock the anchor.
5. When the wire has been tensioned, remove any excess wire using cutters.

Trusted by the Experts:

“Securing the living wall system along this tributary could have been labor‑intensive, but the Gripple Terra‑Lock™ System made the process fast and efficient. With the proper installation tools, pinning the geogrid back into the slope was straightforward and saved our crew significant time while still delivering a stable, long‑term erosion solution.”
“Using the Gripple Anchor System allowed us to secure the erosion control system quickly and with confidence. The anchors saved time during installation and delivered the holding power needed to keep the bypass functional, even as it carried water for weeks during record rainfall.”
