We are looking for some help from anyone with experience of MBC slabs. Its the order of doing things that is confusing us. We believe we need a land drain. We will also have surface water drainage. We have been advised by a drainage contractor to do the drainage (foul and surface inc soakaways) after MBC put the frame up, so probably after the roof is on and the rainwater pipes in place? Maybe before the render because of dirt? So is the best order broadly as follows? Dig foundations, compact hardcore MBC slab MBC frame Roof / windows Drainage (foul, surface, soakaways) plus other service trenches Render / cladding Where does the land drain fit into all this? It seemingly is supposed to go where the hardcore is around the slab. So do we dig that out again (when we do the other drainage) or do we put it in at the same time as compacting the hardcore. Opinions please. And thank you.
