Treating Cold Joints in Walls

[hike]

Hello,

How are cold joints in plain concrete walls typically treated? Are adhesives used to bond the next pour on top of the already set concrete or are dowels inserted to connect the cold joint?

Any input would be appreciated.

Thanks in advance,
Hike

Why is there a cold joint? What is the wall for?

Beyond Dick's reply, cold joints are normally treated as joints and no special bonding is used. If it is a matter of preventing water from penetrating the joint, then a waterbar or properly designed caulked joint can be used. If load transfer is required, consider using dowels and/or a keyway. Cold joints are generally a consequence of the contractor planning a discrete pour based on his schedule or what he thinks he can complete in a day.
