Indian sandstone will create a stylish finish; however, it is important to do your research to ensure that you are choosing the best quality stone for your paving. In our latest blog, we share our tips on how to check the quality of Indian sandstone so that you benefit from the best paving possible.
Check the British Standard
The British Standard BS 7533 Class 2 applies specifically to Indian sandstone, so you should always check for the CE Kitemark when choosing your paving stones.
When it comes to choosing stone for your paving, if the price is very low then it may be too good to be true. Not all Indian sandstone will live up to the BS 7533 Class 2 standards, so a cheaper product may well fall short.
Look for stone with a low level of water absorbency, as this will help to protect your paving from frost, algae, and lichen. Stone which is absorbing a large amount of water will need sealing to improve the performance of the paving.
The higher the flexural strength, the less chance there is of your paving becoming damaged when laid in your garden. Our recommendation is to look for a strength of more than 12MPa, so that your paving can withstand the harsh British weather. Also, check whether the Indian sandstone is resistant to frost, as the freeze-thaw cycle will reduce the strength of your stone.
Look for a stone which has been quarried and manufactured in an ethical way, with many companies taking part in the strict standards of the Ethical Trading Initiative. By sourcing stone which lives up to these standards, you can be sure that workers have been paid fairly and are working in safe conditions.
