Kroombit Creek
Tributary Stabilisation

Project overview

An eroding tributary of Kroombit Creek near Thangool was cutting deeper with every flow. Bellequip stabilised it with rock chutes, reshaped the banks and revegetated the site, then stayed on to maintain and monitor it until the planting was established.

Completed ahead of the date for practical completion, with all project objectives exceeded.
