This was a challenging patio with regards to the logistics of moving materials, due to it being a split level patio build.
As you can see from the before photos there was a considerable amount of work to be done.
The foundations were dug out and ground prepared, a retaining wall was built on the top and bottom levels all round utilising 9 inch concrete blocks.
The ground was leveled and sub-base hardcore laid and compacted before the slabs were laid on a wet sand and cement mix and cut to suit.
You can see the results for yourself.
