Above is the before shot, the sleepers are lining the garden bed.
And heres the after shot, still not finished but at least started and learnt some things on the way.
Close-up of the excavation.
A drain !!!! , (the blue thingy) well lucky i wasn't digging deep as i got lucky and saw this before potentially cutting it (plastic piping), it turns out that its the drain for the shed roof, it goes directly under where i'm going to lay the slab, luckily once again its actually down far enough
Lucky once again, I had to lift up a few pavers to make way for the concreate slabs and it was like striking gold, there was a layer of sand then aggregate then CLAY ! , in the garden was some amazing top soil . It now looks like a landscape supply yard in the back yard but i managed to keep most of it seperated for later use.
Looks like good clay too, i'll do some testing on it another day to see whats its like, the plan is for it to be another outer insulating layer.
