We recently completed a slope stabilisation for RoadTek using Concrete Canvas.
Location: Warrego Highway outside of Roma
Existing grass batters had deteriorated and needed to be replaced.
- We first scoured the old batters and dug a trench along the top of the slopes.
- The concrete canvas sheeting was pinned into the trenches at the top of the 7m high slope, rolled down the slope using an excavator, and bolted into existing concrete slabs at the road base.
- Where the canvas sheets overlapped, they were glued using a special epoxy.
- The canvas was then screwed into the slope every 200mm. Although this was labour-intensive, it was still more time-efficient than pouring and screeding the concrete in the traditional way.
Once everything was in place, we used our water truck to saturate the concrete canvas. This allowed the concrete to cure and set (this process continues over time).
Using the concrete canvas allowed us to install these batters in a much shorter time-frame. It also eliminated the need for a concrete pump-truck and reduced waste and environmental impact.
