Green Slate 40mm is the large alternative to the smaller 20mm version. Our 40mm Green Slate comes from Cumbria so unlike Welsh Slate is chunky so we wouldnt recommend this size for a pathway. It is also used extensively on ground cover, borders and rockery and the natural green colour allows it to blend in to many garden landscapes..
