This big bag contains 20mm plum slate, a decorative aggregate commonly chosen for landscaping work and garden projects. Sourced from quarries in Wales, the slate offers natural colour variation, providing an attractive finish to paths, borders, and other external areas.
Plum slate in a 20mm size is often applied as ground cover to help suppress weed growth, improve drainage, and create visual interest in planting beds and around paved areas. It is also suitable for use around water features, delivering both practical and aesthetic benefits on site.
