Challenge

Platipus Anchors' in-house geotechnical team was commissioned to create a comprehensive design solution for a challenging 6m-high, 137m-long cut slope at Edginswell Business Park in Torquay.

Originally envisioned as a 70° timber crib wall face slope, a value-engineered design was emphasised by Torbay Council, including seamless aesthetic integration with the planned car park at the slope's base.

Project detail

Significant cutting and filling for enabling works was required, while being cost-effective and minimising maintenance requirements. This prompted Platipus to introduce an alternative innovative design, requiring 550 Platipus anchors across the height and length of the slope, driven at approximately 6m depth.

Platipus proposed incorporating a 3m-high 80° cut slope at the base, adorned with a stone mattress façade, while the upper slope would be completed with a 60° vegetated finish, achieved through hydroseeding and underlayment to facilitate growth. Combined, these conformed to cost-saving and time-saving requirements set by Torbay Council.

Outcome

Substitution of the timber crib wall with a stone-filled mattress facade optimised space at the toe and expanded the ecological zone above.

All these achievements were accomplished with a value-engineered framework and tight timeliness, professionally executed by Platipus Approved Installer Topbond PLC.
