There are all sorts of alarm bells ringing here.... "membrane, hardcore crusher..." not what I like to hgear, and then blocks were 'lifted' to generate extra fall, but did that involve scraping out the sand laying course, re-grading the sub-base with additional aggregate, re-compacying it all, and then re-laying....or was it simply a matter of shoving a bit of extra sand underneath the blocks?
The front paving falls directly towards the public highway with no sign of an interceptor drain to prevent run-off, and there is a near absence of any fall or drainage provision down the side and at the back.
Maybe I'm doing this guy an injustice, but nothing you've stated or shown inspires me with confidence or convinces me that he has a clue about pavement construction.
And that projecting pipe needs properly investigating and explaining before anything else is done - it looks like it could be an extension to a pre-existing field drain.
I'm not familiar with the site, so it's difficult to suggest what would be best, but a cursory examination of the photies suggests that all of the side and rear paving needs to come up, a linear drainage channel installing either along one of the walls or down the centre, and the paving re-laying on a properly re-graded sub-base to suitable falls and levels.
