All our concrete gravelboards are manufactured on site at our Derby factory. They are wet cast for a smoother surface finish. Our mix contains 4-10mm gravel aggregate, concreting sand and a 52.5N high-strength cement. All our gravelboards are reinforced with 5.5mm steel rods for extra strength.
Our Medium Rock Gravelboards are 12" high and 6ft wide to match a standard fence panel.
