Hi as title I was in middle of getting a porcelain patio layed, then I was going to grass seed whole area, however I questioned the haunching.
It comes out from my edging blocks at least 50 to 60mm wide, possibly more I never measured, and is square not angled, and is 40mm below the edging, (finished height of patio,) at the bottom is top soil although hard to see and was covered with tarpaulin to suppress weeds until I'm ready to seed.
I said what is the purpose of the haunching being so wide, answer to give the blocks and patio strength, I then said with the ledge haunching etc, only being able to hold 40mm of soil when I bring the top soil level with the patio, surely the seeds have no chance of growing in the shallow soil will die, I'll end up with a bare patch that will likely be replaced by weeds, tried to explain best I could hope you get my points.
