    Hello, it's been a while since I posted here.

    I'm installing a beam and block floor to convert an undercroft into a store room. One end needs to be seated into an existing retaining wall. The wall is 140 dense block cavity with concrete fill. So the plan is to knock out 100 deep pockets for the concrete beams.

    Do you have any suggestions about how to damp proof the end of the beam and protect the exposed end of the rebar? I could wrap the end with DPM but it'd be clumsy. I was thinking adhesive tanking membrane would be neater but I would have to buy a 10m rolls! Or perhaps just using some bitumen tanking paint.

    I've also found a product called k-kaps. Has anyone used them?

    The other end of the beam is supported by an internal wall below DPC so I can simply wrap a DPC sleeve around that just like you would with a timber joist in an old house.
