Gripple - Anchored Solutions
North American Green is a exclusive partner of Gripple®, providing securing hardware for Turf Reinforcement Mats (TRMs), High Performance TRMS (HPTRMs) and transition mats. Gripple® is renowned for providing innovative, cost-effective solutions for erosion control and soil stabilization applications. The Terra-Lock® Percussion Driven Anchors (PDAs) are designed to provide immediate stabilization, requires no crimping and are accompanied by a range of installation tools. Supplied in combinations of Terra-Lock® Anchors, Terra-Lock® terminations and cable lengths, kits are pre-assembled and specific to the project requirements and geotechnical conditions, ensuring considerable time and labor savings.
Anchor assemblies consist of four primary components:
- ANCHOR: The anchor component is driven into the soil developing resistance to pullout. The size and drive depth effect the pullout resistance of the anchor.
- TOP TERMINATION: Grips the ground surface and fabric to secure in place. The size of the top termination can affect the ability to hold the soil matrix. Apertures allows for vegetation establishment.
- TENDON: Connects the anchor and the top termination. Available in galvanized steel or stainless steel, the tendon is a critical piece for long-term performance.
- GRIP: The grip is housed in the top termination and secures the tendon in the top termination.
The Gripple twist pin is an innovative fastener providing significantly greater pullout resistance than typical straight pins or staples. The greater pullout improves performance in soft or sandy soils, allowing in some instances better tie down of permanent RECPs compared to more costly hardware systems. Using a hand drill and specialized chuck, installing Gripple twist pins are quick and easy.
Gripple Twist pins come in two variants, each with two length configurations. The TL-TA1 is designed for loose soils and the TL-TA2 is optimized for hard soils. The TA1 and TA2 are both available in 8 and 12 inch lengths.
