Building on a previous thread - I have an existing large flat concrete slab (used to be the floor of a now demolished garage) slightly under grade of adjacent garden.
I am putting a new shed/workshop there - and am considering casting a new raised slab (100mm or so) on which the shed can sit. I'll then surround the whole thing with gravel to improve appearance.
So - some questions:
- DPM necessary for new slab? Or should I not bother, and instead use bearers on top of new slab on which the shed can sit?
- I have a load of old concrete edging - around 1m x 80mm x 40mm. Can I put these to some use in the new slab? Either sit them inside the formwork to reduce the amount of poured concrete, or alternatively use them on top of the slab as the bearers on which the shed can sit?
thanks
Keith
