Thickness of block pavers

[RSbyTaschen]

I am considering paving an area of with 100x200mm pavers and was advised to go for 60mm thick blocks as opposed to 50mm ones. The area is a domestic driveway and path about 110 square meters in size.
Can anyone offer guidance on this….?

Many thanks in anticipation.

60mm blocks are BS blocks and, with some manufacturers, they are of a slightly better quality than the 50mm driveway products. However, for most residential driveways, there is no problem at all using the 50s.

Depending on where you buy, and which manufacturer's blocks you get, it is actually possible to get 60mm blocks for less than the 50s!

Has your advisor shed any light on why the 60s are preferable, or is it just a thickness thing?

Hi Tony,

Something like 'the extra 10mm makes all the difference..they are less liable to cracking'..

I feel that is flawed: If the sub-base is correct why would they crack?

Only under extreme conditions, such as point loads and, occasionally, during the consolidation phase of laying.

The sub-base is, in my opinion, more important than block thickness for typical residential driveways, but I have to agree that, when it comes to laying and consolidating, we always experienced more breakages per square metre with the 50s than with the 60s, and more breakages of the 60s than the 80s, but then, who in their right mind would use 80mm pavers on a residential driveway?
