Hi all - just a quickie - got a 200mm depth to make up to floor height of existing building in new extension, on top of concrete oversite. Would you (from a cost/ hand mixing cement issue) go for thicker cellotex, or thicker concrete (only needed 75mm of each to satisfy building regs).
What do you recommend as easiest/cheapest option?
Thanks all
