Gripple Terra-Lock System is a geotechnical engineering solution designed for slope stability and erosion control.

The system uses anchor technology and Turf Reinforcement Matting (TRM) to stabilise slopes, embankments, and water-adjacent structures. Terra-Lock System is designed to work with or replace traditional soil retention and slope stabilisation methods, using the natural properties of on-site materials to enhance stability and promote vegetation growth.

Features and benefits

  • Reduces time, labour, and cost in installation

  • Minimises surface erosion from water and air

  • Promotes vegetation growth for long-term stability

  • Transfers shear forces deep into the ground for secure anchoring

  • Reduces flood risk by maintaining engineered size and shape of water assets

  • Controls hydraulic flows and minimises scour

  • Self-healing properties through vegetation reinforcement

  • Minimises downstream sedimentation

  • Made from corrosion-resistant materials for durability

  • Allows for steepened slopes, maximising use of space

  • Lightweight and easy to handle on site

  • Minimises settlement and subsidence in poor soils

  • Installation depth calculated for increased factor of safety

  • Locks surface and retains surface failures

Applications

  • Cuts

  • Shallow slope stabilisation

  • Embankments

  • Channels

  • Riverbanks

  • Lakes and spillways

Materials

Manufactured using corrosion-resistant materials.

Performance

TRM reduces surface erosion and increases allowable shear stresses, preventing excessive soil loss. Anchors transfer shear forces deep into the ground for a secure and stable system. System minimises settlement and subsidence, especially in poor soils.

Installation

  • Insert Drive Tool through the anchor and place against the surface.

  • Use Gripple GPD to install the anchor at the required depth.

  • Remove Drive Tool and load lock system using JackJaw.

  • For a neat finish, use Gripple Wire Cutters to cut wire below grade if required.

Manufacture

Designed and manufactured in-house by Gripple.

Sustainability

System supports greener structures by promoting vegetation growth and reducing CO2 through time and labour savings.

Technical Support

On-site training and support delivered by a team of dedicated technical experts. Hydraulic design service available to ensure correct TRM installation.
