Lesmurdie in the Perth Hills has areas where storm water drains are not part of the street and each property has a drainage trench running along their verge to take care of rain water. We constructed this crossover including a culvert pipe to allow rain water to run under the crossover, and two stone headwalls (one on each side of the crossover). A roadbase / gravel / limestone hardstand basecourse was then installed over the top of the culvert pipe allowing vehicle access from the road onto the property's driveway. 25mm of black granite hotmix / bitumen / asphalt was then laid on this to seal the area and provide a long lasting, durable surface which will last for many years.
