RE: Cost Effective Mechanical Lap Splice?

[Subject Prev][Subject Next][Thread Prev][Thread Next]

Good call by Mr. Feather, as usual.


Bar-lock couplers work very well and I have had no complaints from the ironworkers.

No small feat.

If the lap splice length isn't there, perhaps you could go with a mechanical rebar coupler.  If the splice length is close to what is needed, try a higher strength concrete mix and see if the shorter splice length works.

I'm working on a project where the contractor has installed too short of a dowel coming out of a footing for a retaining wall. I've considered excess reinforcement, but the required lap is still more than what I have.


What is the most cost effective lap splice?
