Firstly the levels are all fine and not the issue I was asking about. They have done what we asked as we wanted the initial point to start at the alfresco height. The water doesn't pool at the retaining wall it goes towards the drain points.
I spoke to the concreter who thankfully agreed in all the points I have mentioned. He is going to come back and re seal to make sure it is even.
With the bricks, he is annoyed at his employees and wants us to organise a brick cleaner and deduct the cost of cleaning from the final payment. Now just have to hope the colour comes of without wrecking something else.
Good. Any reputable tradie would act this way. Word of mouth is a big thing.
He might give them a boot up the bum ...
