Hard armour solutions are still needed in some applications. Gripple has engineered the Terra-Lock™ System as a comprehensive solution but also an effective complement to hard armour, to ensure the best on-site solution is always delivered based on the geotechnical conditions. The use of the lightweight but durable Terra-Lock™ System leads to a significant saving in time & money, and a ‘greener’ solution.
A clear benefit over traditional systems is the green finish achieved by the Terra-Lock™ System. A natural, vegetated finish delivers enhanced aesthetics when compared to concrete which is often susceptible to graffiti damage.
The Terra-Lock system promotes and enhances vegetation growth, making it a sustainable option which allows nature to create its own protection. It’s long lasting, environmentally friendly and can actually capture sedimentation.
Hard Armour installation is cumbersome and often requires heavy tools. The Terra-Lock™ System is installed quickly with hand tools, vastly reducing install times and delivering significant labour cost savings.
Heavy transportation such as concrete mixers is a characteristic of traditional hard armour installs. The Terra-Lock™ System’s use and enhancement of on-site materials, coupled with its lightweight nature, significantly reduces vehicle movements and simplifies handling on-site. Over 4900 m² of the Gripple System can be delivered in one load.
Over-excavating is necessary when installing hard armour, to create the correct hydraulic shapes to facilitate flow. This is then backfilled with offsite rip rap or concrete. The Terra-Lock™ System does not add thickness to a channel lining, thus minimising the necessary groundworks and delivering environmental, wastage and labour benefits.
Heavy Machinery & Plant
Hard armour installs require regular heavy machinery movements during the installation process. The lightweight nature of the Terra-Lock™ System not only reduces install costs but also significantly reduces heavy traffic on site, vastly improving safety. This also delivers significant benefits on sites where access is limited.
CO2 & Other Pollutants
The Terra-Lock System ensures large reductions in carbon footprint and emissions when compared to traditional hard armours. Concrete is responsible for 5% of worldwide synthetic CO2 emissions, whereas the vegetation promoted in the Terra-Lock™ System actively absorbs CO2.
The Terra-Lock™ system complements heavier solutions by utilising anchors; the gabion’s weight and capacity can be increased without the need for extra heavy materials.
