I laid a block paving drive last year and I'm very please with the result, lovely and flat. I now want to add a retractable security bollard, which would mean removing six or so of the blocks and digging a 900mm deep hole to fit the 200mm X 200mm bollard casing.
I'm worried that the immediate area of screed and mot1 will collapse into the hole as I dig (carefully by hand) and I'm going to end up with a complete mess up.
I laid 50mm blocks on 40mm screed on top of about 150mm of compacted Mot1. Under this is clay.
Anyone have any advise or tips?
Thanks very much.
