I need to build new walls on a slab type house with radiant heat in the floor.
Do I need to use short nails so I don't hit the pipes in the cement? Or is there another way to build on a slab house? HELP
Thanks, Tom

Usually anchor bolts are installed where all walls will go when the slab is poured or walls straps are attached to the slab.
Your radiant tubing should be installed according to the blueprints so that it will not interfer w/ any wall attachmnets, plumbing lines or electrical lines.
