I need to fix a wooden stud partition down to concrete when using a damp proof
course between the two. If I use frame fixings, I will pierce the damp course.
And I want to use something stronger than no-more-nails etc.
The damp course is that roofing-felt-like stuff from a roll.
What is the best method of doing this ?
Thanks,
Simon.

Aparently a damp proof couce applied to the inside will simply push
off due to hydrostatic preasure. Any water that penetrates to the damp
proof will run down to the floor, and then what happens to it? What is
normal, so my reasearch leads me to beleive, is to build another brick
skin with the dampproof in the cavity, and then your drilling problem
does not exist.

I suggest you have a look arround a bit before getting too excited
that you have a long term damp solution.

I'm not sure I get what you mean. I have always used brown plugs and
screws. The visquene under the concrete has to take it's own chances but
you should be alright with a 2" inch 10.

I'm sure someone will correct me but the damp course used under the
studding's sole plate is protection against condensation and internal
spills etc.

I thought the OP was sworried about a damp proof cource on walls,
maybe I read it all wrong ..........

Just use some frame fixings .......

Sorry all, I must have not been clear.
I am not talking about the damp course under the concrete, but a strip
sandwiched between the concrete slab and the stud wall sole plate. I want to
include the strip to be paranoid, e.g. damp course under concrete getting
damaged at some stage in future. So let's assume there is some damp coming
up from underneath. If I fix with frame fixings, these have to pass through
the damp strip which makes holes in it. There is no point in putting in a
strip at all if it has got holes in it ! Is the damp strip likely to be
self-sealing around the screws, or should a sealant be put in around the
screws before tightening up ?

I think you are probably being unduly concerned, the small holes are very
unlikely to cause a problem but to be safe you could put a spot of silicone
mastic under the sole plate around the holes where the fasteners will go.

Almost certainly complete overkill, but I'd likely do exactly the same in
your situation!

How about this:

Drill holes (through sole, damp-proof and floor) squirt some mastic
into holes, then insert frame-fixings. I don't see much damp getting
through then. This is belt, braces, and plent of duct-tape too!

In the hole, not around it. But really theres no need. - Unless your
concrete is damp. Paint on waterproofer is another easier option.
