Platipus® – Percussion Driven Earth Anchors 

Platipus® Anchors has over 30 years experience and has proven that the combination of Percussion Driven Earth Anchors (PDEAs) and a high strength facing material to support the load generated by the PEDA will stabilise and prevent erosion in these applications. 


Stabilizing slopes offer significant challenges. Many times the lack of deep rooted vegetation, excess water, poor drainage, and over steepening makes them susceptible to erosion or instability. Platipus® Anchors has over 30 years experience and has proven that they combination of Percussive Driven Earth Anchors (PDEAs) and a high strength facing material to support the load generated by the PEDA will stabilize and prevent erosion in these applications. 


The Platipus® ARGS Range consists of 3 main anchor types

Platipus® S2 Anchor 

The Platipus® S2 ARGS Percussion Driven Earth Anchor (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, HDPE Coverings. 

Platipus® S4 & S6 Anchors

The Platipus® S4 ARGS Percussion Driven Earth Anchor (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, Double Twist Wire Mesh

Noosa Slip Repair & Slope Stabilisation – Queensland

1 Feb 2019

A small, already existing, embankment slope located in Noosa in Queensland required slope repair and stability. Platipus anchoring systems were used with a geosynthetic permanent erosion control matting for a ‘combination solution.’ Thesystem  was also designed and detailed to facilitate and encourage vegetation growth and establishment.

TCDC Slip Repair Tuateawa Coast Road – Platipus® Anchored Reinforced Grid Solutions (ARGS)

10 Nov 2015

The geotech engineers from Opus International chose the Platipus® (ARGS) System for this repair. Part of the reasons it was chosen included the tested and documented performance of the Pyramat® HPTRM when used to preventing surface erosion, while giving a larger tensile strength than that of steel mesh. The high tensile strength and extremely high resistance to UV along with the unique X3® fibres of the Pyramat® HPTRM was needed in this tough seaside environment where the matting will be exposed to salt spray and extended UV exposure.
