County Bunker Lining is a Cream coloured grass with a pile height of 19mm. When laid into a Bunker, simply add the sand on top of the liner & your Bunker is open to play. The sand will work its way into the pile, & then into the drainage holes positioned every 100mm on the grass rubber backing. This allows a well drained Bunker to continue to be just that. All that is needed after that is to keep topping up the Bunkers sand.
