Ground Anchoring Solutions, Designed to Last.

Gripple’s Terra-Lock® system is a fast, reliable solution for stabilising slopes and preventing erosion—without the need for concrete, piles or heavy machinery.

Ideal for embankments, retaining walls, and water channels, Terra-Lock anchors secure erosion control materials and lock them into stable ground, reducing soil movement and surface washout.

Quick to install and easy to maintain, the system allows vegetation to take root, supporting long-term stability and improved site performance.

Whether you’re managing earth bunds or drainage paths, Terra-Lock delivers lasting results with minimal disruption.

Retaining Walls

We offer a smarter solution for constructing and strengthening retaining walls. Installed into drilled points and secured with a surface plate, our anchors use soil mechanics to form a strong, stable connection by anchoring the soil beyond the failure plane and preventing toppling.

Slope Stabilisation

The Terra Lock® range offers a faster and more efficient solution for stabilising slopes. Installed using our Gripple Petrol Driver or hydraulic breaker, the system anchors into the soil without the need for concrete, piling or heavy machinery. By using soil mechanics to create a secure hold beyond the failure plane, Terra-Lock provides long-term stability, supports vegetation growth and reduces environmental and site impact.
Discover our Slope Stabilisation Solutions

Surface Erosion Control

Our Ground Anchors create a strong mechanical bond between the surface layer and the stable ground beneath. This prevents soil movement, reduces surface erosion, and allows vegetation to take hold, enhancing long-term stability

Frequently Asked Questions

The Terra-Lock® system uses ground anchors driven into the stable soil beneath the surface layer. These anchors create a mechanical bond, securing erosion control matting and reinforcing the slope without the need for concrete or piles.

Ground anchors are faster to install, require less machinery, and cause minimal disruption. They also support vegetation growth, making them a more sustainable solution for long-term erosion control and embankment stabilisation.

Terra-Lock is suitable for a wide range of applications including slope stabilisation, erosion control, water flow management, earth bund construction, and securing embankments and causeways

Yes. The system is ideal for managing surface water erosion and can be used to reinforce slopes, drainage ditches, and water pathways.
