Stabilising slopes offer significant challenges. The lack of deep-rooted vegetation, excess water, poor drainage, and over steepening often makes them susceptible to erosion or instability.
Platipus Anchors has proven that with many decades experience the combination of PDEA’s and a high strength facing material to support the load generated by the PDEA will stabilise and prevent erosion in these applications.
Platipus®, ARGS® and PDEA® are Registered Trademarks of Platipus Anchor, registered in England.
The Platipus ARGS® range consists of three main anchor types:
Platipus S2 Anchor
The Platipus S2 ARGS PDEA assembly comes in a variety of configurations with up to 1m of 3mm stainless steel wire tendon, two sizes of HDPE load plate and either a copper ferrule or wedge grip option. The anchor system should be driven through the surface covering material to a minimum depth of 450mm to provide an ultimate holding capacity of up to 250kg. Common facings used with Platipus S2 Anchors include: Turf Reinforcement Matting, Turf Pavers, Geotextiles, and HDPE Coverings.
Platipus S4 & S6 Anchors
The Platipus S4 ARGS PDEA is the perfect solution for granular/non-cohesive soil. The larger S6 ARGS should be used in cohesive conditions. Both assemblies include a length of 4mm stainless steel wire tendon, a choice of load plates and a stainless steel conical wedge grip. They should be driven to a minimum depth of 750mm beyond the failure plane and have an ultimate holding capacity of 1000kg. Anchor depth, spacing and loads should be determined by a qualified Geotechnical Engineer. Common facings used with Platipus S4 & S6 Anchors include: High Performance Turf Reinforcement Matting (HPTRM), high strength Geotextiles & Geogrid, and Rockfall Mesh.

Non-cohesive soils are stronger soils (dry crumbly) and therefore better to work with. Cohesive soil is not as good as there is a lot of water in the soil (clay soil type).
No – the anchor itself does not fail, the soil fails, and therefore an engineer must be involved to determine the type, length and spacings of the anchors.
Anchoring can be used for anything. Most common are TRM (turf reinforcement matting), walls such as gabion walls.
Anchors help with stabilising:
A drain which is inserted into the embankment (like wick drain) and has a head of an anchor. The conduit is inserted into the water pockets to extract the water trapped in the slope. Once all the water is removed the slope is protected with TRM.
Geo’s have a crimp lock whereas ARGS’s have a wedge lock.

The Platipus percussion driven earth anchors offer a lightweight corrosion resistant anchor that can be driven from ground level using conventional portable equipment.
Platipus percussion driven mechanical anchors are a unique, modern and versatile device that can be rapidly installed into most displaceable ground conditions.
The Shear Lock Engineered Slope Retention System is an innovative and cost-effective way to protect slopes from potential landslides and to repair existing landslides.
Access to the the Papamoa region water supply reservoir was in need of an upgrade to maintain safe access at all times.
The project started early during the year when a considerable slip adjacent to the road and very close to a house occurred at the property.
Located in the heart of Meadowbank, Auckland, a sports-mad property owner engaged Contrax to construct their own private hockey turf. Contrax was able to quickly and successfully install Platipus Civil Anchors.
