Platipus® – Civil Anchor Systems 

Plaipus® percussion driven mechanical anchors are a unique, modern and versatile device that can be rapidly deployed in most displaceable ground conditions. 

Platipus® percussion driven mechanical anchors are a unique, modern and versatile device that can be rapidly deployed in most displaceable ground conditions. 

It offers a lightweight corrosion resistant anchor that can be driven from ground level using the conventional portable equipment. It creates a minimal disturbance of the soil during installation, can be stressed to an exact holding capacity and made fully operational immediately. As a completely dry system is also has minimal environmental impact.  

Stress Distribution and Bearing Capacity 

The stress distribution in front of a loaded anchor can be modelled using foundation theory. The ultimate performance of an anchor within the soil is defined by the load at which the stress concentration immediately in front of the anchor exceeds the bearing capacity of the soil. 

Platipus® anchors perform exceptionally well in a granular / non-cohesive soil, displaying short load lock and extension characteristics, a broad frustum of soil immediately in front of the anchor and extremely high loads.

Stiff cohesive soils, such as boulder clays, can also give outstanding results. However, weaker cohesive soils, like soft alluvial clays, can result in long load lock and extension distances and a small frustum of soil in front of the anchor. Consequently, these conditions require a larger size of the anchor and if possible a deeper driven depth to achieve design loads.

Factors that will affect the ultimate performance of the anchor include:
  • The shear angle of the soil
  • Size of the anchor
  • Depth of installation
  • Pore water pressure


Applications Include:

  • Portable Buildings/Structures
  • Buoyancy Control/Pipelines
  • Retaining Walls
  • Slope Stabilisation 
  • Bridges
  • Sheet Piling
  • Erosion Control
  • Gabion Support
  • Rock Retention 
  • Scaffolding
  • Foundations
  • Marine Applications
  • Tunnel Linings
  • Temporary Works
