Can anybody recommend what's the best way to secure a stud wall to a
concrete floor where the DPC isn't too far from the surface. I don't want
to pierce the DPC with a hammer in bolt unless there's some way of sealing
it again as the ground is definitely wet underneath.

Many Thanks

Drill it and use something awterproof. Eg epoxy resin and stainless
screw.

Or if you want a quick corner cutting approach, just use no more nails
all along - I'd drill and fix tho.
