Flagstones & Paving

Black Mountain Quarries supplies a wide range of flagstones, patio slabs and paving for domestic and commercial flooring and landscaping. Unlike cast and reconstituted materials, natural stone is hard-wearing, long-lasting and looks great in all weathers. Its timeless appeal deepens over the years. Our range includes sandstone and granite from our Herefordshire and Cornish quarries, locally sourced stone from other UK stone merchants, and carefully selected imported stone from trusted overseas suppliers. Our British sandstone, pennant and granite is ideal for internal underfloor heating. All our flagstones can be used externally to enhance any landscaping project.

Commercial Paving

Our natural stone commercial paving is cut from solid masonry blocks of silver-grey granite, red sandstone and York stone. All British, it is either lifted from our own Herefordshire and Cornish quarries, or sourced from nearby Welsh quarries to be cut and finished here at Black Mountain Quarries. All our commercial paving is bespoke. Ideal for steps, walkways, kerbs and street furniture, we cut to your specification and offer responsive lead times and attractive prices.


Real stone flooring and paving is both beautiful and affordable. Versatile for both internal and external use, we have one of the widest selections of natural stone flagstones in the UK from our local Llandraw green-grey sandstone to imported Fossil Mint stone and beautiful black slate. Our British sandstone, pennant and granite is ideal for internal underfloor heating. We’ve even got a gorgeous crazy paving! Ideal for kitchens, conservatories, hallways, garden paths, forecourts, patios, courtyard gardens and grand entrances, we’re confident we’ll have a stone that’s the right colour and finish to complement your existing buildings and external environment.
