Effectively it is a best practice guide. If you can't get your hands on the standard, a great guide is the Cement Concrete & Aggregates Australia (CCAA) Data Sheet Residential Concrete Driveways and Paths. Hope this helps. Re: Concrete Reinforcement 16May 21, 2017 2:02 pm kitty1 Thanks. I guess with so many different contractors doing it their way i wondered if there was a requirement enforced by the NCC that must be followed in using reinforcement or not for driveways and concrete paths. I think you'll find they mostly do it all the same way. Some use bar chair, other just pull up the mesh as the concrete get poured to a hopefully suitable level. Bar chairs are more accurate. A residential driveway construction is not subject to NCC. Use reo or not, but you would be a fool not to use it, the concrete will crack more if you dont use it, but as Bashworth said, the substrate is important. If your substrate is clay based soil, it will heave when wet, so you must use reo. As far as walk paths are concerned, you do not use reo for foot traffic, just cut regular stress joints every metre. Bedding sand laid first before pouring concrete works great to reduce cracking. To my understanding early saw cuts are to control shrinkage cracks, so doing them now would be pointless. Control joints may reduce ugly cracking during periods of soil… 3 9857 Hi all I need a guidance on how far I need to space expansion joints in the concrete driveway and its type (keyway/foam.) Contraction joints are at 3m max for a 125 slab. Thanks 0 10939 |
