Putting in a driveway at home, we are on clay and prone to flooding so using permeable sub base and surface.
Need to source Type 3 but there seems alot of confusion about this stuff.
We are using gravel stabilization.
What size do the particles need to be?
Depth required?
Compaction?
Suppliers in NW Kent?

Thanks for any help!

What size do the particles need to be? Depends on depth
Depth required? Depends on size of stone and ground conditions
Compaction? Big roller
Suppliers in NW Kent? Gallager

maybe I have this wrong but permeable drives wont work on clay
much more expensive to install and dont work
linear drain going to a soakway is the normal route

On a clay subgrade Tony is spot on. I have a lot of experience with permiable paving and IMHO it is pointless on a domestic drive but a brilliant idea for big car parks or roads where the water can be harvested and used for anything other than drinking.

Apart from the additional installation cost it doesn't look very nice.
