Great product, great service,delivery turned up a day early!


Third time I have used Gravel Master (different products each time)As previously, easy to use web site, and good value /quality products. Ability to choose a day and for a little extra the am / pm delivery slot, really useful. Palletways driver was super, delivery on the day problematic due to parked cars, but he still managed :) Dropped the pallet / bag exactly where it was needed. A very big thank you to a very helpful driver! All round positive experience, delighted with the 20mm slate.Thank you Gravel Master. Regards Steve
