I am trying to re landscape my small garden at home, and have a small paving area running along the length of a large conservatory.
At present, the slabs slope towards the conservatory, and drain into a 4" wide shingle channel.
I want to remove the shingle when i repave, and replace it with a drainage channel. I am sick of pulling weeds out of the shingle all the time, and it will make it easier to drain water from the surface when i pressure wash .
Problem is, that the shingle is 4" deep, then i hit the concrete footing of the conservatory. I need 5" for the drainage channels.
At the moment. this is 6" below damp, so no room to lift up the paving.
How structural is it if i break out this concrete all the way along??
