Blue Slate 20mm

20mm Blue Slate is perfect for pathways, as the smaller pieces form a flatter surface to walk on.


When wet, the blue colour becomes darker,  so it is ideal to use in and around water features; Blue Slate is fish friendly, so  it can be used in ponds. 


Blue Slate is supplied in Bulk Bags
