We've laid the first drainage pipe down. I had to leave a short while ago, and the guys were working on the trench for the second pipe. Not sure how far they'll get through, but they won't be able to complete it because we don't have enough pea shingle left. If the trench isn't complete, it needs to be dug to 1 1/4 spades deep.
edit: it's looking a bit muddy for the roller at the moment - it'll probably just churn the mud up. We don't have enough sharp sand to cover the surface, so it's up to you guys to figure out what to do
. I was wondering if laying old astro in front of the roller as it goes along might stop it from picking the mud up.
