As well as its design, the Gravel textile tile is inspired by the unfailing robustness of stone. Essentially made from recycled components, it comes in 9 mineral shades. Its 700g structured loop is made from 100% recycled Econyl® polyamide yarn, solution-dyed to make it resistant to trampling, light and maintenance. Its NRB (Noise Reduction Backing) underlay has a sound absorption coefficient αw of 0.25 and is made from 90% recycled plastic bottles. Like all Balsan tiles and carpets, Gravel is designed and manufactured in France, in the Berry region.
