Triassic Posted April 18, 2018 Share Posted April 18, 2018 I’ve finally tracked down the concreting guy. During the discussions I mentioned the need for the concrete raft to have a power floated finish, his response was I’d probably watched too many episodes of Grand Designs! All I really need is a flat, smooth concrete slab suitable for final floor finishes. Do I really need it to be power floated? If not, it’ll save me money!

nod Posted April 18, 2018 Share Posted April 18, 2018 Your better off power floating if you are looking at tiling directly onto the slab Tge only drawback is that it may mean that your contractor has to come back later that evening I think what he is referring to is the trend to polish the slab to a finish It rarely goes well we are watching an episode of building the dream The Architect (Client) has done just that followed by eight hour of heavy rain Not the finish he hoped for You can hire a power float if you don’t mind doing it yourself after the concrete contractor has gone home They are not difficult to use Link to comment Share on other sites More sharing options...
Triassic Posted April 18, 2018 Author Share Posted April 18, 2018 (edited) Just a thought, the concreting guy has asked the volume of the foundations, as it’s insulated home made MBC type raft, it’s should be easy to calculate the volume, but how much extra should I order? I assume too much is better than not enough? Edited April 18, 2018 by Triassic Link to comment Share on other sites More sharing options...

Russell griffiths Posted April 18, 2018 Share Posted April 18, 2018 I suppose it’s the difference between your opinion of a finished slab and his. How is he planning on finishing it? does he care if you have to use 30 bags of self levelling compound on it before you fit your floor coverings as it will be a year later and he will just be a distant memory. I would want some some type of reassurance that his finish is good enough. If he has lots on it would be easy enough to show you some work he has recently done.

Most skip companies now take a very dim view of using a skip as a dump ..! Link to comment Share on other sites More sharing options...

Yeah but it’s very easy to calculate the exact amount for a slab i worked out out prior to poring that I would need 95 cube for footings I was three cube out and just added it to the last load Link to comment Share on other sites More sharing options...
Pete Posted April 19, 2018 Share Posted April 19, 2018 We had about a cube to get rid of and we just spread it very thinly on the drive. It is easier to break up afterwards if you need to move it than have to break up a large mound of the stuff Link to comment Share on other sites More sharing options...
