dowel into existing concrete

dowel into existing concrete

(OP)
We will pour concrete against two existing walls one on either side. I want to dowel into the existing concrete. What steps are needed?

RE: dowel into existing concrete

Drill a hole, epoxy in a dowel, spaced as wanted.

RE: dowel into existing concrete

Can you provide a sketch of the configuration? What are the loads on the walls? Do you expect any settlement of the new wall or consolidation of the soil?

RE: dowel into existing concrete

Also if there are going to be lateral pressures (i.e. soil loading) we typically have a steel angle installed on the inside face of the new wall and fastened to the old wall with either dowels or mechanical/chemical anchors. This angle provide lateral bearing area instead of just relying on the dowels.
