Can you use slate chippings for a driveway?
Larger slate chippings (20-40mm) are perfect for creating stylish and functional driveways. Their durability and low maintenance make them an ideal solution for outdoor spaces that experience heavy traffic.

If you’re creating a driveway or path, opt for larger slate chippings (20-40mm) for added durability.A 20mm aggregate would need to be at least 40-50mm deep, and at least 50-60mm on driveways. A larger aggregate will settle and bond together better than smaller ones. The depth you will need to select for your gravel or slate will always depend on the aggregate size and what the surface will be used for.For a sturdy, long-lasting driveway base, use gravel that includes a mix of crushed stone gravel up to 1. This combination compacts well and creates a solid foundation.
Is slate cheaper than gravel?
Lastly, the colour and aesthetics of your chosen aggregate can complement your property’s exterior, with slate providing a more natural appearance. Additionally, cost can be a deciding factor – slate is generally more expensive than gravel but offers a distinct, timeless look. However, slate is usually more expensive upfront. Tile roofs, made from clay or concrete, offer a lot more variety in colours, shapes, and finishes. They are durable too, but typically last around 50 to 70 years and can be more prone to cracking, especially in freezing conditions.
Do I need a membrane under slate chippings?
We recommend ensuring the area underneath slate chippings is compacted and laid with geotextile membrane before laying slate chippings. Not only will a membrane layer reduce weed growth but will also stop chippings from working into the soil, making them last longer and be more stable. Slate chippings can actively reduce weed growth but some weeds may grow through. For this reason, we recommend a weed proof membrane be used to place as a layer before adding the chippings on top. Fix your membrane into the ground with pegs, cutting holes where you intend to put flowers and plants.For areas without foot traffic such as garden borders, edging detail or for planting areas, a sub-base won’t always be necessary. However, we would recommend applying a layer of Weed Prevention Membrane beneath the slate to stop weeds from growing through. This will also help improve drainage.
