How it Works The Gripple Anchor System gains its stability through the creation of a truncated cone of soil. This consolidated mass provides the resistive securing body and is formed in two steps: Step One: After driving to the correct depth, the wire is tightened; this rotates the anchor so that the load bearing surface is parallel to the ground surface. Step Two: The wire is further tightened to compress the soil above the anchor’s bearing surface. The compression transfers towards the surface to form a cone of soil which prevents further anchor movement.

The load bearing capacity of the system is determined by: anchor size, anchor depth and soil shear angle. Due to the complex interaction between these factors, a geotechnical report should be utilised as part of the engineering plans to ensure the appropriate anchor size and drive depth are selected.
Installation
Step One:
Insert Drive Rod through the Anchor and place against surface.
6
Step Two:
Use GPD to install the Anchor at the required depth.
Step Three:
Use JackJaw® to remove Drive Rod and load lock system.
Step Four:
Use Gripple Wire Cutter to remove excess and cut below TL inset level.

The Hillsboro canal is managed by the South Florida Water Management District and forms one of the local flood control system’s main arteries. Following regular inspection, a 10.5 mile reach was identified as being in need of significant repair where sections of the bank had eroded and fallen into the canal. This presented problems to local infrastructure and homes which run parallel to the eroding banks. A solution was chosen to ensure functionality of the canal for decades into the future. It was decided that the lower portion of the slope was to be armoured using ACBMs which extend below the waterline. Above the ACBM, where turf alone provides insufficient erosion protection, HPTRM was used. In both instances, a Gripple Anchor System was chosen to provide ease of install and a high factor of safety. Owing to the specific requirements of the two matting products, a broad Gripple Anchoring System was employed utilising: TL-100, D4 and TL-400–A (ACBM Plate) as terminations. The hard, underlying soil contained coral rocks and presented tough driving conditions. However, use of the GPD eased installation and allowed a drive depth of 1.2 m (4 ft) to be achieved. Each of the anchors was subjected to a load test requiring at least 80 kg (180 lbs) of pullout. The Gripple Anchor System passed all tests as part of this process and provided the safety required even under tough conditions. The broad system used on site benefited from a wide range of install tools including: GPD, JackJaw®, Drive Rod, D4 Tensioner and Wire Cutters. 8

Five Mile Creek is a water management canal which protects local homes by acting as a vital flood defence. Previously the banks had been armoured with HPTRM, however this was secured using only straight pins with a low pullout resistance. Following an intense rainfall event in which 457 mm (18”) of rain fell over 12 hours, the river level rose dramatically, broke its banks and flowed into homes. During this event, the armoured slopes had sloughed and lost much of their integrity. Clearly a system with a higher factor of safety was required. To correct the failed slopes and provide protection into the future, the banks were first re-graded, then armoured with rip rap at the toe and HPTRM up to the head. The high flow velocity of the channel necessitated increased pullout resistance of securing methods. As a result, a Gripple Anchoring System was chosen to secure the HPTRM and provide an additional factor of safety. This system has subsequently been proven to be effective, holding under a 203 mm (8”) rainfall event. The sandy soil meant that the GA2 anchors were easily drivable to a depth of 1.2 - 1.8 m (4 - 6 ft) and comfortably met the required 70 kg (150 lb) pullout resistance. The installation process was eased through use of Gripple installation tools including; GPD, JackJaw®, Drive Rod and Wire Cutters. On
this site the JackJaw® was of particular importance, allowing for straightforward extraction of the Drive Rod.

C-41A, Okeechobee, Florida, is a major waterway managed by the local water management district. The local soil is extremely soft and consists mainly of very fine sand and silt. As a result, erosion is a constant issue as it causes major damage to the banks of the waterway as well as heavy siltation of the channel which could damage local habitats and infrastructure As part of a previous conservation project, the banks were protected using HPTRM. The mat on this occasion was laid using only rock ballast at the head and toe. This was then overlaid with turf. Subsequent to the work, the rocks at the bottom of the slope had been washed away, which then led to the HPTRM floating up and losing any effectiveness by exposing the toe to undermining. A more secure solution was provided by the Gripple Anchor System. This time when the HPTRM was installed, anchors were placed underwater at the toe and all along the slope to the head. This ensured that the HPTRM maintained intimate contact with the subgrade surface, thus providing the erosion protection required. The system makes use of the time saving, purpose-designed TL-100 which provides security, aids the ease of installation and has minimal impact on vegetation growth. This component coupled with the range of Gripple Installation Tools ensures a swift, straightforward and correct set up is achieved every time. 10

The Central Arizona Project directs water through a number of canals extending from the Colorado River into particularly arid regions within the state. Canal realignment construction was completed in 2011. Since the completion of the project, graded slope areas around the perimeter of the outlet structure of the Prima Canal have experienced substantial erosion. As a result the area was designated for repair and protection using erosion control matting. Although degradable short term rolled erosion control products were initially discussed, it was suggested that an anchor reinforced vegetation system utilising HPTRM was to be used to extend design life. As part of this solution, the Gripple Anchor System was used as a method to add security to the matting. The System employs a number of elements which aid installation ease, reduce installation time and provide a bespoke solution for the securing of HPTRM. Central to this system is the Gripple Ground anchor, the design of which enables straightforward penetration of the mat without tearing or otherwise damaging it. On this project the required 0.9 m (3 ft) drive depth was reached with ease through use of the GPD and Drive Rod. The TL-100 top termination secures the matting in place and by utilising patented Gripple technology, is able to secure the wire under load without the need for time consuming crimping. The open face of the TL-100 allows vegetation to grow through, so that when the root systems begin to establish themselves, the Gripple Anchor System supports rather than competes with natural securing methods. www.gripple.com
