As a customer how do you decide whether to buy calibrated paving slabs or invest in thicker slabs which will cost slightly more?
Over the last decade natural sandstone paving has become increasingly popular as a landscaping material in the UK, and there seems to be a lot of choice out there.
Most of this product comes from India. There are now thousands of different suppliers across the UK and to most consumers they all appear to be selling a very similar product. The most popular products you will be offered are Raj Green and Fossil Mint Sandstone, plus there are a number of other colours less well known such as Kandla Grey, Modak, Cathedral, Mellow Yellow, Buff and Black (They are known by various different names given to them by different retailers). However, not many of these suppliers have any control over the quality or ethicality of their supplies.
