Support for footing reinforcement
Support for footing reinforcement
(OP)
At a recent visit to a job site, I was observing the reinforcement for a cmu cantilevered retaining wall with a concrete footing. The hooked dowels extending out of the footing were supported by tying an additional vertical rebar to each dowel, and embedding it in the earth.
This seems like a very poor practice in that it provides a path for water to enter the footing and corrode the reinforcement.
Should I make the contractor remove the embedded rebar and support the dowels with chairs or small cmu blocks? Anyone know of any articles addressing this concern?
Thanks

You should reject it immediately and have the contractor do it right.

In reality, unless the soil is very aggressively corrosive, by the time the entire length of rebar corrodes so that the rest of the steel can begin to corrode and cause a problem, the structure has probably lived its useful life anyway. I'd make them fix it since you saw it and it violates code and is another magnet you're wearing for liability.

UcfSE- Where in the code is this prohibited?

As I see it they are porous enough to provide a path for water to get to the reinforcement, or at least compromise the concrete cover.

I used to okay these sorts of things, but I have since learned that there can be problems with durability as a result.

Take a look at some of the reinforcement and spacing products available. They are not all thin wires that sink into the sand. There are a number of choices.
Poly Lock(sp?) has a complete line of supports for single and multiple layers at mutiple heights and many other very specialized situations. They are relatively open, but you can get some of them with a large enough footprint for granular or wet grades.
