repointing vs existing bituminastic DPC

[dormermike]

Hi There

I'm having the bottom few rows of brickwork in front of two bays repointed, and quite clearly the bituminastic DPC (original, circa 1930's) is visible. The pointing is in very poor condition and is original black mortar variety.

I've had a very good quote for someone to come in and repoint it for me... I asked about the bituminastic DPC and they said it would be fine to rake out to a depth of an inch or so (forget actual depth) and repoint.

Just looking for second opinion on this.. or should I ask them to leave it alone?

Thanks
Mike

dormermike,
If the existing mortar is soft and it can be raked out without damaging the DPC then yes it is worth doing. If the mortar is hard raking out will remove some of the DPC and may give you problems with damp.

From what i can tell there doesnt seem to be mortar on the line where the dpc is, just bitumen. I guess the builder will know what he's doing anyway i just like to know for myself :)
