Browse Forums Building Standards; Getting It Right! 1 Jun 01, 2009 6:14 pm Gday guys, I was hoping for some advice for my brother who has just started his build. His slab has been poured, however it has come clear that all the piping has been laid about a metre out in different directions..... Not quite sure how this happened, but as you could imagine, he is stressed to the max about it. The framers were due to start last week and upon marking the walls on the slab, they found that the toilet pipe was in the bedroom etc etc. I am not a building guru, but have told him that I might be able to get some info from people in the know about where they stand. His SS knows about it and there is apparently an engineer going to visit the site sometime this week. Will this effect the structural guarantee? It is a waffle pod slab. If they jackhammer the slab and run pipes to the correct positions ( I am assuming horizontally) will that increase the likelihood of the pipes becoming clogged? If anyone can help with the situation, please let me know. Thanks Ryan Building Vancouver 33 - My Thread https://forum.homeone.com.au/viewtopic.php?f=31&t=89689 Re: Slab gone wrong.... 2Jun 02, 2009 7:18 am There are quite a few options.... Generally they will cut the slab to where the pipe should be, dig down and join new pipe (or cut the old)... Couple of things to make sure... When refilling the pipe slots cut into the slab, they use reo to tie either side together... This will probably mean the use of dowel into each side... Make sure they use reo in the actual slot... Many will simply use a slurry mix.... Make sure the termite barrier is reinstated! This one is often forgotten! And get a guarentee in writing that there will be no problems for 10-15 years...

We also have a wafflepod slab. They jackhammered down moved the pipe and then put extra re-inforcement and refilled with concrete. They also put extra termite protection. Aparently its a common issue. Not an ideal one, mind you, but a common one. We have had no issue with it.

The blame game will start pretty soon, make sure your bum is covered. Who set out the piping? and based on what information? Were they provided with a fully dimensioned set out plan? Good luck, Pat. Re: Slab gone wrong.... 5Jun 02, 2009 11:38 am Ryan Oliver ... your brother will not have to pay for this error. They have stuffed up and will need to rectify according to building standards. No charge should be passed to yourself as they are fixing the error due to the fact the didnt follow the plans that are in the contract. How far out of place are the pipes. One of ours was out by over a metre. Are his larger than that?? Living in Caloundra Thread****** Lovin my house all finished!!!
