up to almost the final part of the big deck build trying to level the ground along one of the edges. I’m building up with topsoil as in the pic (having first stripped back the turf and roughed up the soil underneath.) new turf will then go on.
I’m goong to make sure there’s 150mm of top soil everywhere but few questions :
- how much do I need to compact the topsoil before turf goes on ? It’s probably 3-400mm deep at the deepest part.
- what do I do to the topsoil before laying the turf - just rough it up a bit or water it etc ?
Using hand tools only so hopefully will get a reasonable result. I’m trying to minimise disturbing the lawn as it’s in really good shape.
There is a bit of welding - I made some pretty clever posts to hold those sleepers in place.
We used to 'walk in' the base before turfing. It involved walking across the area using your heels to compact the soil, walk, turn, walk, turn etc. Then do it at 90 degrees...same method. This is very hard on the legs and it helps if you can find volunteers to do it :whistle: :D
Then lightly rake level, lightly apply some fertiliser and lay turf.
EDIT: As said above, that's a lot of topsoil which'll nedd 'firming' a fair bit before final preparation.
For compacting the topsoil, you want to make sure it's firm but not overly packed—just enough so it can support the turf without sinking later. A good rule of thumb is to walk on it a bit to settle it down before laying the grass.
As for prepping the soil, a light raking to break up any clumps should do the trick. You might want to water it a little to help it settle, but don’t soak it too much. Keeping the existing lawn intact is smart, especially if it's in great shape.
When I was working on my own yard, I went with a local luxury landscaping company Ottawa, and they had some great tips for keeping the yard healthy while making changes.
