Browse Forums Building Standards; Getting It Right! 1 Dec 16, 2015 8:44 am Hi, Help please... We're first time home buildings, building with a major project home builder. Our slab was poured yesterday and below are some are pictures of a hole or gap at the edge of my slab between the portico and our study. My questions are as follows: - Is having a gap/hole such as this normal or it's something we should be concerned about? - If it rains, will water be able to get under the slab via the hole/gap? - If water is able to enter and get under the slab via the hole/gap, will this affect the slab's strength or lead to future slab cracking and/or other slab issues? - If it is a problem, what can be done to rectify this? Would appreciate anyone who has any ideas to provide some advice/information. Thanks.

I do understand that the site supervisor is busy and probably do look after around 17-18 sites. As we are still at early stage of building our house and try to work out how to deal with our site supervisor in the best way. What I am trying to understand is whether the site supervisor has the obligation/responsibility to accompany us and look at something and explain to us in case we feel somethings are not right, or it is at his discretion and up to him decide whether there is a need to accompany us to the site? I would assume it is common practice after each stage (such as slab, frame etc), we will be offered to walk the site along the site supervisor? Am I making wrong assumption or asking too much?

Thanks very much It's your house, not his. It's your build not his. His company is contracted to you! Advise them to stop the build until you verify with an independent inspector and also give written notice of a date and time to meet on site to discuss your concerns. CC in your contact at head office. Do you have paperwork showing your slab design? edit: Looking closer it seems they haven't included your alfresco area in to the main slab design so they have poured your slab and then the alfresco is a secondary pour. I would have expected to see signs of rebar as well in the corner but others more qualified might be able to comment. Re: Hole in new slab - please help 5Dec 16, 2015 5:39 pm Hi Gunna, Thanks for your tips, What is the slab design? Does it show how the slab supposed to be poured? Do you know where would I be able to get it from? I did go through CDC by the way. Thanks very much Water this close to the slab edge or under the slab can cause slab heave or subsidence and is potentially a serious problem especially on highly reactive clay soils.
