Interesting site here BTW:

Note two things

Early on thee page he says "No ascending dampness by capillarity, but
consequence of current splash-water, water sucking cement joints" =
rising damp!.

Look at the brick wall in the pool of water. Makes my case that modern
cement is a DPC in itself . Note he has NOT used lime mortar here.

Look at how sodden the brick is UP to the first mortar joint.


Whilst I am happy to agree that many so called rising dmp problems are
not, in older properties it does exist and is a serous isue IF you want
to modernise them.

If you leave the chimneys open, burn coal and don't plaster the walls or
fit double glazing, why? that's how they were designed in the first
place!. Draughty (well ventilated) and heated by a means that would
RAPIDLY dehumidify them in winter, and with the windows wide open all
summer, and no wood anywheree near the brcks..not that lasts more than
60 years, anyway.

The issue comes when you have a 100 year old place built out of soft
brick and lime mortar with no DPC and you want to at least make it un
draughty and use CH. Here injection will work. IF you can get to all the
walls. But if its single brick I'd just s soon put in a concrete floor
WITH DPM And insulation and possibly UFH as well), run that up the walls
and tank over up to about 2 ft, or better still, dry line it with foil
backed board and celotex, and let all that dees come up get outside, not
inside.

A chimney or spine wall is always gong to be a bugger. Its just always
going to be damp at the base. You can't really inject very sucessfully.
Rally you have perhaps just two choices..tank it up and cover it in
render, or let t BE a chimney and tank it up where you want to plaster
over it, and put some sort of waterproofing between it, and any wooden
flooring etc.

Frankly a victorian semi or terrace is my idea of hell anyway. I'd pull
the ****ers down and build something better on the land personally. But
there you go. Victorain rectories and decent gerorgian hosuses are worth
keeping tho. They tend to have been better built to start with. A lot of
victorian stiff wasn't built to last and it hasn't. Theres not a lot of
timber framed 300 year old stuff around either - when I pulled mine down
I found out why ;-) It wsa allegedly a farm building originally - almost
a barn. Never built to last, or house people, but somehow it did.
