Also as a post for something i've actually done.
We ripped up the old artificial grass as there was more real grass growing through it then fake grass! The previous owners had done a poor job and not used a membrane underneath and there were quite a few dips. Although to be fair it was 12 years old.
We took it p in November and covered the area in plastic sheet as we couldn't get hold of anything and the weather wasn't favourable. It's been like this ever since!
I took the plastic up and picked up all the bits of leaves/grass that was in the sub base. Draining the water was a pain as i didn't want to just tip the water and leaves etc down onto the base below so had to use a cup to scoop it all up!
I'd removed the top 2" layer of sand from the previous install as i planned to re-do it with granite dust.
It then got dark, but i was worried i didn't have enough dust and didn't want to have to wait till tonight to find out, so went out with my headtorch to get it down and see how much i was missing. Action shot!
This isn't a job for when you're having regular visits to the physio for back pain!
Just need to finish this bit tonight and then fit some wood for the long edge to the left as that bit was all rotten and i ripped it out, we've also moved the border slightly so i have the fun of digging out compressed sub base without destroying too much of it either side!
Then hopefully getting the grass down and nailing it will be the easy part.
