New Lawn - Drainage?

Sneachta

Hi folks,
I have removed the grit from left hand side of the garden to the front of this picture at the left of the hedge and am going to put in a lawn, I am going to move in the soil from the front lawn. The soil underneath is very well compacted. The soil from the front garden probably isn't great. There is probably more moss in the lawn than grass.

Just wondering is there any point in digging a deep hole and puttin in stones.
Would this drain away the rain?

Or is there any point in using say a crowbar and making a few deep holes to help drain water away?

I have lots of stones at hand.

Any help very much accepted about any aspect of this job.

Please give some advice.
I have searched boards but haven't found the answer.

You could run french drains down through the (future) lawn in a herringbone pattern & end them in a small soakpit-like structure. Don't forget to use geotextile.
Better off getting in some quality topsoil if the stuff out front is no good - you might end up with a patchy lawn otherwise.

Why do you feel you need extra drainage - is water ponding in your existing lawn?

Theres quite a lot of moss on lawn and it gets fairly wet and rain builds up a bit. Just want to ensure a nice lawn with good drainage. Water not a major major problem.

Theres a very shallow gully to the right of the hedge which runs towards the house where it meets a manhole. Might see about draining water there.

IMO installing French drains in such a small area to be a waste of energy and resources. Simply mix in horticultural grit with soil and dig several times. Its a very small area so shouldn't take too lone.

Not quite clear, but is that blue PVC under the existing pebble, if so this will have trapped water and probably diverted the run-off to a particular point thus causing some 'flooding' . When using weed barriers, gardeners should use permeabler membranes, ie a woven structure which allows oxygen as well as water to pass through.

Thanks Sonnenblumen,
Thats just some blue bags of stones you can see in the picture. What exactly is horticultural grit?
