St Leger Subdivision, Te Awamutu – T-Recs TRM & Platipus ARGS Anchors

The designer on the project selected T-RECS to be applied to the large swale drain below the stormwater overflow ‘bubble up’ which was a steep slope (approximately 1V:4H). Once the T-RECS was applied to the soil, it would provide the client with a robust solution that would ensure the site could handle a large storm event with minimal soil eroding and therefore protecting precious aquatic life in the stormwater pond below.

Design

Cirtex was able to offer the designer a robust solution that would be able to handle flow velocities of up to 7.6 m/sec coming from the stormwater overflow while maintaining a natural green look compared with traditional ‘hard’ alternatives such as concrete or rock. With the addition of the Platipus S4 Anchors, this solution would also address the risk of shallow slide failure.

Installation

The Cirtex account manager worked closely with the contractor throughout the installation process to prevent downtime. This included visits to the site to provide installation support and collaboration with the Cirtex logistics and customer service teams.

The products used provided the following benefits to the project:

• A natural vegetated finish
• Strengthening of the slope to be able to handle flow velocities up to 7.6m/sec
• A solution to minimise the risk of shallow slide failure
• A long term erosion control measure
