Browse Forums Building A New House 1 Nov 05, 2015 4:53 pm G'day, For those of you in Melbourne, you're no doubt aware of the massive down pour we've all experienced in the last several hours (as of Thursday the 5th of Nov'). I was interested to see what Mother Nature is capable-of; concerning a half built house [30% bricks, 95% frame, no roof tiles]. On arrival, there are several puddles of water pooling right against the slab on the west and northern sides. There is absolutely no pooling on the southern and half of the eastern side of the slab. The puddles/pools of water are no deeper than 10cm and no bigger than say 2ft by 3ft. We have had quite a bit of rain at the site over the last couple of weeks and had noticed absolutely no water pooling on the site or up against the slab and I check the site daily. To Mother Nature's credit, we too have had stinking hot days to counter what rain we've received. However, it's near impossible to describe how heavy the rain was today - but it was pretty darn heavy! So, the question is - is it acceptable to have water pool up against the slab when: 1) we have such a heavy down pour; & 2) when a home is still under construction? I just don't want to jump the gun if some water pooling is acceptable - especially if it can be deemed as 'temporary' pooling. When should I get worried about it? We have a concrete raft slab (no waffle pods/foam, just clay dirt and concrete) in H2 soil. Cheers. Re: Water pooling around new Slab 2Nov 05, 2015 7:14 pm Hi it is not acceptable.YOU SHOULD BE WORRIED RIGHT NOW.Take a lot of photos in case you have problems in the future,so you have evidence that there was water against your slab during construction.Let your ss know ASAP.

Re: Water pooling around new Slab 7Nov 05, 2015 9:40 pm Interesting I was worried about the same with some forecast rain that didn't really eventuate, the SS and engineer both assured me that a bit of water against the slab was no problem at all. I even got told that it was better than being too dry! It is really hard to know what to believe after reading the 'slab heave' thread. Re: Water pooling around new Slab 8Nov 06, 2015 5:59 am I literally checked my slab as soon as the Mother Nature stopped shooting Shotgun pallets. After reading, my take on it is if the water is still there after it's been given an opportunity to drain away, then I have a problem until I can lay a concrete perimeter. As mentioned earlier, we've had rain on and off but nothing as heavy as yesterday. I've never noticed it before. Fingers crossed it has drained away by the time I check it this morning.

Take photos you may need it in the future.I assuming the builder has no temporary downpipes installed This certainly doesn't look good. I would be engaging with an independent inspector to have a look at this.
