I'm getting my garden weeded and rotavated shortly and hope to get some artificial grass laid down. I just need to know what other preps and material I'll need to do prior to this. The chaps that are doing the rotavating just do garden clearance so they won't lay the grass itself.
If you are rotavating you will certainly need a layer of Type 1 stone compacted with a vibrating plate ..then a layer of sharp sand compacted before the membrane...not a 'piece of wood with a hammer'as per the link.
