Once Weathered Coping Stone

A once weathered coping slate means the slate has a gradient to one edge of the slate. These are mostly used around parapet walls when the water runs off to the back edge and then falls behind the wall. When using this style of coping slate you will usually require an overhang with a drip groove cut into the underside, we recommend 6mm fluted groove 25mm in per side to create your overhang.
