Base for drive using clay pavers

[ardhall]

I am planning a new drive and the intention is to use clay pavers. Using the links on the web site, I identified a supplier, Chelmer Valley Brick Company. I quite like their Cotswold range.

However, the contractor has raised a concern about the thickness of the pavers being 50mm vs. the normal 65mm for concrete ones. He has indicated that using the typical compacted MOT type1 plus sand that the drive would then only be suitable for light vehicles.

We have a situation where it is possible that heavier vehicles may use the drive and we would be unable to control that, therefore I am looking for a solution.

I have emailed the supplier to ask if he has 65mm but am not hopeful.

The contractor said that another alternative would be to use MOT type 1, then a layer of lean mix concrete, then sand as before plus 50mm blocks.

This might even be less expensive than thicker bricks.

However, it is a viable solution or is there another way to achieve the desired result?

thanks

Clay pavers can be a bit fragile and 65mm is the norm for drives even though Tony suggests that 50mm will be OK.

Putting lean mix under it would help but personally I wouldn't advise it. If you want to go this route then lay them on a rigid concte base.

OK.

The procedure for laying rigid paving on concrete looks like quite a performance - mortar joints, expansion joints etc.

Would it be acceptable to lay Type 1 then C20 or whatever soild concrete is, followed by sand and then the pavers on that as though that part was flexible construction?
