A hauling tarpaulin for landscaping and similar uses is composed of a flexible first sheet of fiber-reinforced plastics material and a flexible second sheet of plastics material. The first and second sheets are connected to each other with the top face of the second sheet in facing contact with the bottom face of the first sheet. The second sheet has smooth bottom face, a thickness greater than the thickness of the first sheet, and a flexibility allowing both sheets to be rolled or folded for storage. The sheets are secured to each other by rows of stitching, and the stitching is protected from abrasion by protective strips. The stitching passes through intermediate strips to which the protective strips are secured by an adhesive layer.
