Setting anchor bolts in mono-slab for interior load-bearing wall


5/8" anchor bolts set at 24" OC. Pouring a mono-slab. Setting anchor bolts on the exterior is easy (either wet-set or attach them to forms). How do you set them for interior walls? If you wet set them they'll inevitably be in the wrong place. There's no form to stick them to for prepositioning? So how do you do this?

You can do all the measurements ahead of time and set up a straight line laser to place them or drill in wedge anchors later.

Rockite might be a product that would be satisfactory in your application.

Re: Setting anchor bolts in mono-slab for interior load-bearing wall


We worked with a foundation crew that made the same mistake on ever house.

Our plans always show interior was measured from the outside of the house to the centre of the wall. I don't know how may times we had to cut off bolts and put in anchor bolts.

Re: Setting anchor bolts in mono-slab for interior load-bearing wall


Thanks guys. So are the expansion bolts an acceptable replacement (per IRC) to cast j-bolts?

We do it all the time with a 5/8" 6" but you should maybe ask the powers that be first.
