Kandla Grey Sandstone Calibrated 22mmPrices are including VAT. Part of the character of Sandstone paving is that no two stones are coloured the same; however, when combined they create a rich tapestry of colour to make an overall hue as presented here. Seasonal changes also bring differing perspectives to the reflected colours. In strong summer sunlight, a sandstone patio will appear to have less colour variation, whilst after rain, the colours will be of deep patina.
