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. When you get a chance watch the last couple of videos. The cracks are pretty bad, it's almost as though he hasn't put any reo in that corner and hasn't compacted/levelled… 2 3358 You are fine. The concrete is never going to explode. Worse case scenario is that it develops a crack from different rates of expansion but hopefully it's got some… 5 4509 |
