That's good news for you. It means that it is possible to build
soakaways that lead down into the gravel, and at least ensure
that you can eliminate standing water. Assuming that the gravel
drains, of course :-)

I don't know if the clay FAQ has details, but building such
soakaways is well within the ability of a jobbing builder or
someone with a reasonably functional back! A 4' cube of wet
clay is of the order of 3 tonnes.
