Ditch drainage repair

The Old Maitland Road Upgrade project was located near Tuggerah on NSW’s Central Coast. This important connection road was upgraded to support future growth in the region, including a plan to potentially build a residential development in the township of Mardi. Central Coast Council required a quick and affordable option for the planned swale drains alongside the road, with traditional paving methods deemed unsuitable for the area. Some swales were located up to 3 m above road level and not easily accessible by equipment. A flexible and creative approach was needed to avoid bringing in concrete pumps and the time and cost associated with it.

Much faster and cheaper to install than conventional materials, TILTEX is a unique solution for concrete applications. For projects where receiving trucked-in premix concrete is impractical, or remote sites where no local concrete batching plant is available, TILTEX solves geotechnical problems on embankments, trenches and swale drains, helps to stabilize slopes, and can be used for mattress spillways and bund lining.

Central Coast Council chose to use the 2,5 m x 7 mm material, rolling out the TILTEX with the use of a dispenser with ease and minimal labor requirements. Hydration to activate the product was easily achieved with a water cart.

The result was a solid water diversion swale, directing all the runoff from above directly into the water catching drains. In just two days, the team was able to install and hydrate 400 linear metres over the pre-graded surface.
