Hi there,
I have recently moved into a windmill (sloping walls) and there is a
problem with penetrating damp on the North and North East walls. The
areas have been recently pointed but water ingress continues. There is
a small step (25mm) about 11ft up the exterior where a wooden walkway
was located. The builder has mortared this creating a slope of mortar.
Was this the right thing for him to do as I understood pointing only
works where it is flush with the stone?
There are signs that porches have been ripped away over the two doors
and the flahing there looks very very old. What specific problems would
a 10 degree slope cause and how do I combat them especially when
creating new porches?

Hope somebody can help.

Cheers


As Rick says, I wouldnt assume its penetrating rather than
condensation. Even in places where water lies on the outside, this will
lower internal wall temp and tend to cause condensation. Really you
need to establish whats going on first.

10 degree slopes... I've no idea what you were referring to there. We
also dont know what materials or finishes are involved, which make a
big difference. Maybe some pics would help.
