Replacement Damp Proof Course

[karoo]

Hi Guys,

Could some one tell me how many stretcher bricks that I am allowed to remove in a straight run in a solid wall.
Reason is that I want to fit a plastic damp proof course. The wall has been chemical injected twice and I am still suffering rising damp problems.
It is of the old bitumin type and has deterioated. The wall damp course is not bridged or anything like that.
I am led to believe it is in the region of a meter what can be removed, can anyone confirm or give any advice how to tackle this job.
Thanks

It can vary depending on the masonry.

A typical scenario wound be to remove four then leave four and so on.
