We acknowledge that water is a powerful and destructive element that can destroy our work unless appropriate precautions are taken during the construction period. Over a period of time it can erode even bedrock, so it is little wonder that water can weaken the sub-bases of roads that lack appropriate subsurface drainage and eventually cause the road surfaces to collapse into cracks and potholes.
The risk of damage to a tar road can be minimized by appropriate base preparation and reticulation. You can cut initial costs and take a chance by just laying a tar road, but the chances are good that rainwater will wreak havoc in just one wet season. This false economy will send you back to look for a contractor like Donnstein that has extensive experience of repairing roads damaged by water action.
