Welsh Slate. A recycled bi-product of the roofing industry, this material is used extensively as a cost effective mulch which alleviates water evaporation whilst providing a permeable surface for plants and wildlife.
The three colours are washed and supplied in 20 mm and 40 mm grades and used extensively in hard landscaping. Slate is also tumbled to provide smooth rounded Paddlestones in a 50 - 100 mm and 100 mm size.
