When I installed the interior framing in a 3,500 sq. ft basement with 
tubing in the slab, I set the walls in place then ran a bead of glue 
along the edges of the bottom plate, sort of like caulking around the 
bathtub. This held everything in place surprisingly well, as I found out 
when it was later decided to remove one wall entirely.
I had to plane off the glue and broken slivers of wood left behind with 
my widest and best quality  chisel... :-(

The walls near the foundation were safe to spike in place since the 
tubing was either one foot or two feet from the exterior walls. This was 
good because we needed to seal the poly to the concrete here with a 
tarry looking sealant. (disgusting stuff that never hardens, AFAIK, but 
tends to ruin your clothes....) We drilled a series of holes (1/4", 
iirc) in the bottom plate then drove in about three nails in each hole, 
the wedging action holding everything securely.

The glue was probably something like Bulldog PL 600, an exterior grade 
that's extra tough. I realize a some people would prefer to not use glue 
if there's an alternative, but this is a trick to keep in the memory 
banks just in case...

Cheers,

Chris Green.
