Resin bound mixes natural aggregate, marble or recycled materials and clear resin thoroughly together. During this process, each particle of stone is fully covered in resin and laid immediately onto a base, to a smooth permeable finish.The finished depth of a resin bound paving surface varies between 12mm and 24mm - depending on the size and type of stone used and the application (e.g. driveway, patio or path). Using a resin bound paving system allows us to combine different sizes and colours of stone, offering a wide variety of finishes.To summarise a resin bound system delivers a permeable, durable, accessible, multi-layer surface. Because the finish is smooth there is no loose stone - guaranteed.
