None of the travertine products available on our website are suitable for driveways. You would need a product that is at least 50mm thick to give sufficient strength to take the weight of vehicular traffic. Usually when travertine is being used for a driveway small blocks are produced such as 200 x 50 x 50mm and these are laid in the same way you lay concrete block paving, this provides the additional strength needed to take the vehicular weight.
