Block Paving Sinking - what action to take?

[CortinaV8]

I do, 1972 Mk3 with a V8 motor, it lives in the garage though

Will try and get some photos of the sinking when it's light. It is actually more towards the house where the drive has sunk, the front half of the drive nearest the road is fine! Only in the areas under the wheels, no ruts etc.

WIth clay beneath, I would have thought a tough fabric between the clay and the type 1 would have been in order - it helps prevent the two layers mixing.

As far as I know, the fabric is only for if the hardcore is large pieces only i.e. for a permeable surface. Proper Type 1 that hasn't separated out has the right proportions of dust and small aggregate so it shouldn't be able to sink as there shouldn't be any voids. So far, that's been true for our drive...touch wood!

"Permeability" is not the criteria for when planning permission is required.

MOT 1 is not in impermeable in any case.

And the MOT is not on the surface either.

Not so according to Guidance on the permeable surfacing of front gardens - Gov.uk

of course the type 1 is not on the surface. That is irrelevanthe anyway.

It is according to the actual planning regulation.
