Description

Our 20mm blue slate chippings are recycled in the UK from the roofing industry. The blue colour gives it a bold, contemporary look which can help bring your garden to life. The flat, angular shape of the slate also provides a stylish modern look and helps to stop water drying up in borders and planters whilst still allowing water to pass through for plants and wildlife.

When you purchase blue slate from Gravel Master, you can take comfort in the fact that you're dealing with the UK's #1 decorative aggregate supplier on Trustpilot. We have more than 35 years experience supplying the UK and guarantee a professional and reliable service.
