We just moved into a house. The back lawn is going to be re-turfed. Have created bedding sections around the lawn but there are loads of rubbles, bricks, half bricks. I have also just seen a huge old patio about 12 inches down.
My question is how much of this stuff do I have to extract, should I leave it to the professionals, and if I do remove it how far down do I have to clear it.
Also, do these bricks help with drainage in any way and should I leave any of them there?
