Engineered strength that instantly locks in stability

The Gripple Terra-Lock® System is a cutting-edge solution for erosion control, slope stability, and soil retention. Engineered for rapid installation and long-term resilience, it combines corrosion-resistant anchors and geotextiles to lock into structurally sound soil, even on steepened slopes.

Its lightweight design reduces settlement and subsidence, while promoting vegetation growth for a natural, self-healing finish. Terra-Lock® actively prevents surface failure and sediment loss, making it ideal for challenging geotechnical environments.

With load capacities up to 7,300 lbs-force (32.5 kN) and reduced embodied CO₂, it’s a sustainable alternative to traditional hard armor. Whether reinforcing embankments or stabilizing riverbanks, the Terra-Lock® System delivers strength, speed, and environmental benefits in one intuitive package.

How it works:

Our Terra-Lock range is designed for fast, simple installation using either hand tools or plant machinery for harder ground or larger scale projects. See how it works below, or download the Technical Data Pack for full installation guidance.

 Download the Technical Data Pack
1. Place Drive Rod into back of anchor, and position anchor perpendicular to the slope in desired location.
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.

Frequently Asked Questions

The Terra-Lock® System is designed for erosion control, soil retention, and slope reinforcement. It uses ground anchors and geotextiles to stabilize surfaces and prevent failure, especially on steep slopes and embankments.

Thanks to its lightweight components and intuitive design, the system allows for quick and easy installation. Anchors are driven into structurally sound soil, reducing time on-site and minimizing labor costs.

It promotes vegetation growth, reduces sediment runoff, and uses corrosion-resistant materials for long-term durability. Compared to traditional methods, it significantly lowers CO₂ emissions by minimizing the need for heavy material transport.
