My wife and i just brought home our little baby girl. It's our fourth child and our house is feeling abit cramped. Time to finish off the basement. My question is how to secure the bottom plate of the stud walls. I get really nervous thinking about driving nails into the concrete and hitting wirsbo tubing. Can I just use polyurethane or constuction adhesive,or does it need to also be nailed? And how deep into the slab is the tubing generally.
