Circular and rounded repairs have been used in the aviation and shipping industries for many years for example, to repair wing damage. The shapes have also been used for windows and doors on both planes and ships. This is due to the scientifically proven strength of the circular shape not having any corners that allow water ingress and thus keep their integrity.
Road Mole have developed this proven way of thinking and are introducing this to the highways maintenance industry for repairing defects in asphalt using Road Mole Systems.
The below diagram shows a Road Mole Circular reinstatement uses less asphalt and is stronger than a traditional square reinstatement.
Road Mole circular repairs for potholes and iron works have proven longevity of 8 years+.
