Blue Slate Chippings 20mm
Our natural recycled Blue Slate Chippings 20mm are one of our most popular decorative aggregates that are ideal for garden borders, landscaping projects, pathways where a flatter finish is required and as a fish friendly product it can also be used in fish ponds and ornamental water features. This true Welsh Slate is a pale blue grey when dry and darkens to a plum blue colour when wet. PLEASE NOTE: Our Blue Slate products are a TRUE Welsh Slate material which may differ in colour to blue slates purchased from other retailers who may source their stone from elsewhere. If you are attempting to match slate colours, please order a sample before ordering. Currently, our Blue and Plum Slate products may have some similar colour tones due to the quarry seam that is being mined at present. We supply in various quantities of 20kg poly bags or bulk bags of approx. 750kg. Our images show the product wet and dry. We also supply a larger 40mm Blue Slate, Blue Paddlestones and Large Slate Paddlestones, all of which are also available in a variety of other colours. Please see our sizing info.
