These pavers are 40 mm thick and if you are planning to use these for a drive a full mortar bed is recommended. Please note these block pavers are new but the crates have been in storage for some time and as such the crates are not in pristine condition. These pavers are a natural stone product and as such the colours may vary slightly (please see pictures of the pavers laid on my drive). Any questions please ask 07722150158?
