Browse Forums General Discussion 1 Jan 26, 2009 9:51 pm The concretors didn't stick to the plans with the wet/tiled areas drop-downs in the slab. The plans specified 40mm, they, at best, did 20. Is this going to cause problems down the track, with screeding and tiling the slopes to waste ??? Should I arrange for a bloke with jackhammer to scoop it to the specified depth ??

we currently have the same issue on our house being built. The area for our shower was supposed to be recessed down an extra 50mm to allow for the frameless shower. Ours however was not recessed at all. Our independant inspector said this must be done otherwise we will have water drainage issues. Like all our other problems, we have notified the builder but they have done nothing and dont seem to care. It is not the only problem with our slab. Some of the slab was not poured to the drawings. It however didnt stop the brickies, who did the brickwork to the drawings and consequently some of the brickwork isnt even on the footings. Once again our supervisor doesnt seem to care even when our inspector said it has to come down and be redone.

I'm an Owner-Builder though, so I had it measured and will adjust the plans for frame and brickies accordingly. One up for O-B! But I still need to know about that drop-down I'm planning to have the electric-under-tile-floor-heating there and I need to know if to jackhammer the area deeper Chris My father rode a camel, I drive a car, my son flies in a jetliner, his son will ride a camel.Saudi saying Re: Wet areas drop-down??! 4Jan 28, 2009 8:12 am Your problem could lie in that with a 20mm setdown you will have to screed that with fall to the waste. if you have 10mm fall then you are relying on 10mm of tile bed which could become drummy.
You wont have heating in the shower as it Electrical and not allowed. What is the flooring in the next room. Sometimes if you have a timber floor on the slab in the next room you have 15mm ply and 19mm flooring less your tiles gives you an extra 20mm for bedding. If the next room is carpet then you wont have any extra. Without seeing it it,s hard to say but if you are definitely having a tile bed and not sticking the tiles down directly then i would lower the depth. HTH Regards Paul Re: Wet areas drop-down??! 5Jan 28, 2009 8:56 am Thanks a lot Paul. I'm planning to have a glued on 16mm bamboo floor next door, or cork, to similar thickness.
I'm going to consult a tiler for a definite advice. Chris My father rode a camel, I drive a car, my son flies in a jetliner, his son will ride a camel.Saudi saying Re: Wet areas drop-down??! 6Jan 28, 2009 11:12 pm Just to round this off - I've asked for advice:
- a builder - he said "maybe, but rather not worth the trouble" - a floor heating supplier - he said "our wiring will be OK with 20mm screed" - a tiler - he said "check the slopes with the spirit level. If there's drop towards the waste, don't bother, otherwise scoop down to the speced level" I love practical advice. I grabbed the spirit level - no slopes or wrong way, so.... here come the diamond saw and the jackhammer!
