Browse Forums Building A New House Re: 140mm post dynabolted into concrete slab 5May 14, 2018 8:06 pm arcadelt mj-mac4 Hi everyone, we are building with coral homes in nsw. We have just had our 140mm posts installed and they are trying to tell us that this is normal. The bolts are sticking up and not flush. We got told that this is standard procedure. Can someone please clarify if this is acceptable? We were expecting the bolts to be flush. Thanks It may be common with Coral Homes, but it is certainly not good tradesmanship. I would have thought that the stirrup would have been concreted in when the slab was laid. Given that it wasn't, I can see why the bolts are at an angle because the upright would have made it difficult to get the impact drive to drive perpendicular to the slab surface. That said, they could have used a stirrup with a wide bottom flange to avoid the problem. Thankyou for your advise arcadelt! Much appreciated 😁👍🏼 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.

In my case I bought structural LVLs and scraped them back and used them as joists. 1 3526 yep, clearly mark where the infloor heating pipes are before drilling or nailing 1 5462 |
