Riven Black Slate Flags

The rustic riven exterior slate flagstone is a real favourite with our landscape gardeners in the Cotswolds. With Grey and blue tones through the surface the slate exterior flag makes a real statement to an outside space. The dark tones are a great contrast next to the green backdrop of a landscape or building. We also do interior slate flagstones for kitchens and whole groundfloors.
