Other than exothermic welding, what other methods are permitted to connect the #8 to the rebar in an inground pool?
I am aware if the Greaves "Jones Bond" system, but is there another acceptable technique?

Redsy,
For a lot of years, we were allowed to tie wire the conductor to the rebar. That's a BAD method as the steel tie wire has a tendency to go away.

Mechanically, a split bolt is still acceptable, if you're using #4 rebar, you need a 1/2" split bolt (Like light bulb designations, rebar is sized by how many 1/8" increments - ie: #4 = 4 X 1/8 or 1/2")

ALL mechanicals are subject to failure, they are getting weaker the day you put them in. Add Chlorine, lime and all other chemicals associated with pools and concrete the subject grows quickly.

I gave up anything but cadwelds long ago, I've had to dig up too many pools where the other methods were used - NOT installed by me though. If you go with the mechanical methods, take a lot of care in the prep.

they can get nearly any mold to you PDQ

Wouldn't a listed Ufer clamp work?

I don't believe that a split bolt is listed for that application.

How about an acorn that is listed/labeled for direct burial?

BTW,
The Greaves "JonesBond" connectors seem to be the best listed mechanical method.
I'm having trouble finding a local supplier that stocks their stuff.
I may have to order a whole box.

When I write on an inspection report that something needs to be listed I am very careful to write "listed for the purpose". I think an acorn clamp could be used if listed for rebar attatchment. I think a listed Ufer clamp is the best bet, and that is what I require in the feild.

Ryan,
The Ufer installations I've seen were either a compression "C"-tap or a water ground with one half reversed like this -- {{.
Do you have a picture of a listed Ufer ground clamp?

Redsy: I don't have picture but I will take one tommorrow. I see them everyday here.

Redsy: I want to make sure you realize I'm not blowing you off here. I looked the other day for a clamp, but I didn't ahve much time to hunt for one. I have a four day weekend and will spend half of the day Wednesday at IAEI board meetings. Hopefully I can get a picture for you Wednesday or Thursday. Sorry

Thanks, Ryan.

I will wait patiently.
