Plum Slate is 40mm and is a decorative slate that derives from Wales. It is used to create mulching borders, especially in and around ponds as the slate is fish friendly. When wet, Plum Slate darkens in colour and glistens in the light. The Bulk Bag is ideal for larger projects offering 10m2 coverage, however smaller bags are also available. The 40mm Plum Slate is perfect for filling gaps in between patio slabs and can be used for water features because of its fish friendly properties. Products made up of natural materials will vary in size and colour, some significantly.
For best results, we recommend a depth of 40–50mm for decorative areas, and around 150mm for driveways that need to handle vehicle weight. Our calculator is based on a 40mm depth to help you estimate easily.
Please note: Timber and stone are natural materials, and as such, variation in colour, texture, and natural markings is to be expected. We strive to represent our products as accurately as possible through imagery; however, colours and shades may appear differently depending on individual monitor settings such as brightness, temperature, and contrast. These variations are not considered defects.
