Concept to Completion

The Platipus® Percussion Driven Earth Anchor (PDEA®) is 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 conventional portable equipment. It creates 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 it also has minimal environmental impact.
