Reinforcing an exisitng unreinforced footing
Reinforcing an exisitng unreinforced footing
(OP)
Does anyone know of a procedure to grout new reinforcing into an existing, unreinforced footing?
Perhaps, there is a method to drill an oversized hole, insert a bar and then grout it solid.
My footing is 48"sq x 20" thick and I don't need a lot of bars.
Thoughts?

If drilling is an option, you could provide Dywidag bars through the footing with external anchorage subsequently waterproofed.

since you must know, we are enlarging the footing.
and yes, I have checked it for plain concrete.

If it is being enlarged to 48" square then I would drill and epoxy rebar into the existing footing. If you are talking an existing 18" square footing, just replace it.

rather than focusing on my question, the hijacking of other people's posts, as you have done to me before, only distracts from getting to the solution.

I think BA and the rest of us were just trying to help. But if you just want an answer to your original question, find yourself a 48" drill bit, dig down beside the footing to allow access for the drill, and go for it.
