I got fed up trying to grow grass in NY garden. Soil is crap, no sun and it’s more of a yard anyway! Decided to rip the lot out and put down artificial grass so the kids can actually play in the garden. The local cats hate it and stay away which is another bonus! Just do the job properly would be my advice….
I created a border with 4×4 timber, then a about 140 mm of ballast sand then 50 mm of sharp sand…. Then a whack with a whacking plate. Take time to get level! I also used some foam underlay which stops weeds growing through and makes it softer underfoot.
Been down for almost 8 months now and it’s still looking as good as the day it went down. I put a very slight slope on it down to back gate so rain just runs off (it’s permeable anyway so water will not sit on top)
