It would probably be fine to put your concrete slabs down and fill in the gaps with concrete, just make sure to put underground tape over the slabs. Pete Thanks and good idea. Think you just swayed my mind back towards a continuos slab. I had designed the system in the start with that in mind...why I have four 32mm underground conduits ready to go to allow for future expansion. But then I thought I have these 2x2 foot 10cm slabs lying around and to use them. My old man's a sparkie...he said the same thing - don't forget to put the marker tape down and infill with sand before capping with cement!
