Excellent product exactly as described. This is our second order in the last 2 weeks. Easy ordering and this time the delivery was excellent. Will use Gravelmaster again.

Phoned to discuss my requirements with two super staff, Rhiannon and Kirsty who assured me of their company's products and delivery service which was important. The price matched any on the Internet and delivery was exactly when I wanted it... almost to the minute ! The driver also positioned the bulk bag to the very best spot possible. I was quite surprised, I must say. Well done since it was sent to Scotland. The 40mm green slate was slightly larger than I was expecting, but that was fine too. Gravelmaster has my unreserved recommendation. My contractor took a note of this company because he was impressed too.

Easy to find this product, easy to order and the delivery was exactly as requested. The chippings are in a good mix of sizes with none of the 'bottom of the barrel' tiny fragments or just dust that I have found with other suppliers. Once watered down to remove the dust the slate looks great! Shifting it from the bag and levelling it over the ground was hard work but then again shovelling 40mm chippings is a lot harder than sand or pea shingle!
