Natural black slate flakes in the 30/60 mm size, with their flat shape, are ideal for decorating and mulching flower beds and gardens: spread over the soil, the flakes prevent weed growth and reduce water evaporation.
Natural black slate in the 0,6/2 mm size is used as a protective layer for bituminous membranes: it gives greater resistance to weathering, protects the membrane from UV rays and extends its service life.
Natural black slate flakes are available packed in 1500 kg big bags.
