Browse Forums Building Standards; Getting It Right! 1 Dec 19, 2015 10:10 am Hey. This is in regards to our house which was built about 2.5 years ago in Queensland. Basically, the concrete from driveway to front door has a crack. The path is about 1m wide maybe and the crack is completely from one side to the other. We mentioned this during build, and all they did was cut another line in the concrete, probably too avoid further cracking I think. We were not too happy with this resolution but we were tired of the whole build process and all the million things we had to nag about and double check ourselves. It's gotten worse now though and we are thinking we should do something about it. How wide does the crack need to be for the builder to have to fix it? And what would the fix be? It's aggregate concrete or whatever it's called. Is this covered under the 6 years or is it too late now? Re: Cracked concrete new house - how long is warranty etc? 3Dec 19, 2015 12:29 pm I have no idea what that even means... I'll try and dig through all the papers some day and see if I can find anything like that, but won't be able to do it for a little while. Re: Cracked concrete new house - how long is warranty etc? 4Dec 21, 2015 10:51 am Your engineering drawings are from the structural engineer who signed off on your house. The articulation joints are where he would have specified the slabs or paths to have articulation joints/construction joints etc. These are where there are breaks in the slab at controlled points to stop concrete slabs cracking formed usually either by a rigid 10mm piece of bitumen impregnated material that is flush with the top of the slab or by cutting the slab post-pour to a specified depth.

Hi tompad Post up some photos and I'll take a look Generally structural cracking will need a structural engineers certificate to force a builder/contractor to act. Why are cracked driveways and paths generally not considered important and ignored by some builders/contractors 1. driveways and paths on ground aren't structurally critical and aren't enforced by codes and regulations 2. Because of above..Most home owners don't insist on proper engineering specs & inspections for driveways and paths 3. Often It is difficult to appoint blame or prove the underlying cause of the cracking, eg is it the concrete, soil, compaction, durability, rebar placement etc,etc, so drive way cracking is often ignored 4. Structural Analysis of failure & computer simulations can be very expensive and are dealt within the courts Here in WA Engineers certify all Structural concrete..unscrupulous builders/contractors get away with what they can else where so you need to keep an eye on all other work, or hire someone who is competent to carry out the work in the first instance.HTH Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs Plumbers 'can be' plumbers, made all the worse by self certification which the building surveyor invariably accepts as proof of compliance!
