    Default Levelling small area of concrete floor

    Hi everyone
    Doing a reno and have pulled out our old toilet, and toilet walls. This area will now be a little alcove for our new room. The floor is a suspended concrete slab and has vinyl tiles at present. Will place new vinyl on once finished.
    Problem is where the toilet is the concrete is not level. It rises from the old wall up to where the pan was (probably an area of 500mmx500mm, rises aound 20mm). It is solid concrete, not a thin layer, have tried chipping back and it is SOLID. So looking at some ideas. I was thinking of chipping it back but wondering what could level it off with. For concrete would expect I would have to chip back quite a bit, don't want to undermine strength of fllor though. Wondering if some flooing people may know of any levelling product and whether best to speak to them about it. Any ideas would be appreciated.
    Cheers

    I've used this stuff: http://www.ardexaustralia.com/produc...ay.asp?catid=2

    It can feather right out to a couple of mm.

    Ardex is the go as Silent has pointed out but read the lit as 20mm may be too thick for the product. If it is I would partly level before you use the ardex with a topping mix. This is a concrete slurry that uses 6mm round river pebble as aggregate - let it go off then ardex over the top for a smooth finish.

    Thanks Silent C and Bleedin' thumb.
    I was hoping to chip away the 20mm excess then level out to existing floor height, so this product will be good as I won't have to chip away too much.
    What sort of price does this stuff cost and is it available at Bunys? Also what would be the most efficient depth of the product, ie: just a few mm or 10mm etc?
    I'm sure I can find this info on the site, but just thought if you had the info in your head it may be quicker!!
    Cheers

    Not cheap, I think it was in the order of $60-70 for a bag. I got mine from a mate who owns a Thrifty Link - he had to order it in. Don't know about Bunnies.

    I used A55. It can be used to any thickness but needs aggregate added if you go over 10mm. I had 2" to cover, so I used a concrete slurry first and then put the leveller on after a few days. You want a rough surface and there's a primer that you paint on first.

    Hey SilentC, do you mind if I ask a couple of questions?

    How much area did you have to cover? Did you put flooring over the top of it?

    We have a large area downstairs that has a sloped off concrete floor, obvously for drainage, that has been built in with brick walls, but just under legal height to be "habitable" (by about 4 cms). The quandry we have, mainly related to council restrictions and dollars and which is easier.

    Options are:

    1. Remove concrete, dig down, install new posts, re-slab
    2. Request relaxation of ehgith restrictions from council, and lift house roughly 20cms to allow for levelling of floor using timber.
    3. Request permission from council to modify tip of roof to bring house back down under legal heignt and go with option 2
    4. Level out parts of the floor using self-levelling compound for tiling over and using as pool room and bar area, then leave the rest naked for the next owner. (can still be used as laundry as it isn't THAT uneven).

    We of course intend to consult with a builder and an engineer.

    Sorry to impose on your topic Mcblurter

    We sorted it out. Was one layer of concrete over another so easy to remove and just levelled out with some new concrete.
