Overview

Avoid costly rework to suburban service trenches

Rough surfaces increase road user costs. Over recent years many roading authorities have reported instances of poor trench reinstatement that gave rise to road surfacing problems.

To improve public relations, reduce the possibility of accidents and reduce maintenance and road-user costs, present day performance based procedures are requiring that trenching and reinstatement contractors take greater responsibility for their actions.
