Hi. I am having an extension done and had to be away quiet a bit for work reasons so not always there to see what was happening. Floor slab has been poured about 10 days ago and i noticed the thickness is only around 50-60mm (no mesh). Building plan specified 150mm hardcore, 25mm sand, 1200 dpm, 100mm insulation, 1200dpm, 100mm concrete and 75mm screed.
Now i am not sure what to do about it now. Is it going to be ok, this is going to be living/kitchen. To get the floor level with existing floor i reckon we are now looking at 100mm screed on top of this slab. Being a novice, can i ask what is the solution now? Can concrete be poured on top of this slab to bring the level to 100mm?Does it need breaking down and re-pouring or i might get away with this 50-60mm concrete slab with 100mm sand/cement screed without major problems in future? Many thanks in advance
