A very common question is can flagstones be used for driveways? This is usually down to homeowners wanting to use indian sandstone as a driveway which would stereotypically be a method used for a decorative patio. The answer is indian sandstone and other flagstones can be used for driveways however not all flagstones is suitable for laying a driveway as most of them are not thick enough to support the weight of a car.
Flagstones are split into 2 categories: concrete flagstones and natural stone flags. Like most materials there is a huge range in quality and caution should be applied when choosing the right flagstone for your driveway.
Budget concrete paving slabs should never be used for driveways due to the very low cement content the manufacturing process focuses on low costs rather than high quality, most manufacturers will not replace any damaged economy flagstones used for a driveway. Some of the best manufacturers do offer high quality concrete flagstones with a higher cement content but you should be prepared to pay a premium and should always check with manufacturer to ensure that they are suitable for your driveway and how much weight you intend to park on it.
Natural stone has become very cheap and readily available online and at discount depots, once again you must be very careful when selecting your flagstone. The vast majority of natural stone whether it is Yorkshire stone or Indian sandstone or anything else in-between is too thin to use for a driveway. We only recommend using heavy 30mm thick or thicker as it is extremely rare for this grade of natural stone to crack under the normal weight of driveway traffic. A general rule of thumb is the thicker the better, 40mm is ideal but will not be cheap. Light or pale colours should also be avoided as they often show tyre marks quickly after the installation, darker colours are much more forgiving.
