Browse Forums Building A New House 1 Apr 06, 2011 9:58 pm Hi I'm new to the forum, and building. My wife is keen to have polished concrete in our entrance, kitchen, lounge, family and dinning room. The builder is installing a 'M' class waffle slab. I have 2 questions 1) Is it possible to polish a 'M' class waffle slab? 2) Can this be done after handover? I look forward to hearing from other members Thanks in advance Re: Polished Concrete 2Apr 06, 2011 10:04 pm There are a LOT of polished concrete threads... It might be worth doing a search for them, quite a bit of info you might find of interest. However, a start would be : Grind the concrete 3 days after the slab is poured. Cover it then finish the polishing process before second fix. Where you are coming from is where you are going to... To my understanding early saw cuts are to control shrinkage cracks, so doing them now would be pointless. Control joints may reduce ugly cracking during periods of soil… 3 9862 Hi all I need a guidance on how far I need to space expansion joints in the concrete driveway and its type (keyway/foam.) Contraction joints are at 3m max for a 125 slab. Thanks 0 10942 |
