Black basalt is the market's toughest stone and it has been used for paving stones in severe climates. If you are looking for a stone merchant in Cardiff or the surrounding areas, we can help with our natural paving stones selection. All our products are selected carefully by hand from the quarry and are delivered to your doorstep. Our basalt paving stones are of superior quality and are more durable than sandstone slabs, or granite pavers. For any landscape stone supply, get in touch by email at
