20mm Grey Slate Chippings

Enhance your outdoor space with the clean, natural look of our premium 20mm Grey Slate. Responsibly sourced from the well-known slate quarries of the North Wales mountains, this decorative aggregate brings a subtle nod to the rugged beauty and heritage of one of the UK’s most iconic regions.

With a blend of soft greys, cool charcoals, and light silver tones, each piece reflects the layered stone landscapes of Snowdonia. The 20mm size offers a finer grade, creating a smoother, more uniform finish—perfect for pathways, borders, plant beds, and container displays where a neat appearance is key.

Strong, reliable, and easy to maintain, grey slate is a practical choice for any garden. Its durable nature stands up to the elements year-round, while its natural tones deepen when wet, giving a richer, more defined look after rainfall.

Ideal for both contemporary and traditional designs, our 20mm Grey Slate provides a timeless and versatile finish inspired by the enduring character of North Wales.
