When it comes to building a visually appealing traffic island or lane delineation system that provides a safe, designated, and clearly defined area of refuge for vulnerable road users, Quicksetts are the clear choice. The beautiful rustic polish of quicksetts makes them look like granite setts but without the digging. Quicksetts, on the other hand, need not have a subbase prepared before being distributed on top of asphalt or concrete. Quicksetts are designed with chamfered edges to make them safer to walk over while still providing a tactile vibration to alert cars to lane departure.https://quicksetts.com/jpproducts/lane-delineation-traffic-islands/
