PYRAMAT and LANDLOK: High Performance Erosion Control

Project: Charleville Flood Mitigation

Project snapshot

The town of Charleville in western Queensland has experienced major flooding over the last few decades. A number of significant recent events have caused a combined damage to the township in excess of $100 million, affecting both public and private infrastructure.

Murweh Shire Council commissioned a team of engineers to undertake various flood studies and complete the detailed design documentation for a major flood alleviation scheme around Charleville.

It was proposed to raise the height of the existing levee around the town and to address the issue of ‘breakout locations’ which had not been identified in earlier studies that had used more simplistic hydraulic modelling techniques.

As part of the overall $14 million scheme, significant investment was allocated to protect various structures in the Bradley's Gully area involved in the diversion of waters around the township.

Our solution

High Performance Erosion Turf Reinforcement Mats sold under the trade names of PYRAMAT® and LANDLOK® were specified for use in this critical part of the works to ensure long term protection of channels.

Both PYRAMAT® and LANDLOK® are synthetic rolled erosion products that are capable of withstanding high hydraulic forces when designed and installed correctly.

To date, Murweh Shire Council has purchased some 22,000m2 of PYRAMAT® and 10,000m2 of LANDLOK® with installation being undertaken by local Queensland Transport and Main Roads teams.

LANDLOK® turf reinforcement mats trap more seed, soil and water in place than traditional hard armour products, yielding faster and fuller vegetation. All of our TRMs are made of 100% synthetic, UV-stabilised components and are completely non-degradable.
