Tumbled slate is a recycled product from slate debris, it is then crushed and classified, then artificially rounded off, the rounding is done wet so as not to lose colour tone and that the rounding is finer.
Perfect product for use in tree and plant areas as it maintains the humidity of the soil and due to its grey/black colour the dirt in the leaf litter goes unnoticed.
Available in size 12-40 mm. in bulk or in big bags of 1,000, 500 and 250 kg. also in 20 kg. net bag.
