Frequently Asked Questions
Common questions about our slate, aggregates, and UK pallet delivery.
Where does GardenSlate source its slate from?
Our slate is sourced from the Nantlle Valley in Eryri (Snowdonia), North Wales — one of the UK's most renowned slate-producing regions, known for its rich plum, blue-grey, and green slate.
Do you deliver across the UK?
Yes. We offer pallet delivery across mainland UK. Standard delivery is £64.59, extended zones are £91.44, and remote zones are £157.66. Local LL postcodes receive free delivery. Some remote Scottish and island postcodes are quote-on-request.
What pallet sizes do you offer?
We supply quarter, half, and full pallets. The right size depends on your coverage area and material — use our coverage calculator at /calculator to estimate how much you need based on shape, depth, and material density.
How much area does one bag of slate cover?
Coverage depends on chip size and depth. As a rough guide, a 20kg bag of 20mm slate covers approximately 0.25m² at 50mm depth. For exact quantities, use our calculator which factors in material density and your project dimensions.
Is your slate suitable for driveways?
Larger sizes (20mm and above) are well-suited to driveways and pathways. Smaller chippings (10–14mm) are best for borders, ground cover, and decorative features where a finer finish is desired.
