finding your web site very informative, but thought I'd ask for specific advise before I started to lay any flags,
I want to lay a patio across the back of the house, we've had an extension built & a garage knocked down, so part of the area has a concrete bed which is sound, I have back filled across the garden with hard core from some of the garage base that was removed. To level it I was going to lay a course of grit sand then beding, but how much sand should I lay before the beding layer
Also due to the level of the concret I was thinking of either using a drain chanel against the wall or using a french drain? what do you think would be best
here's a picture of what it looks like now
ps i
I'm going to be using indian sandstone in mixed size's which can be seen as a rough setting guide so I can trim the concrete to length, also I will be using some sleepers as a retainer & black granite sets for an edging
