Walls – use construction adhesive alone to attach pressure-treated wall plate to concrete floor

basementconcretewalls

Replacing walls in basement due to flooding. Contractor installed sump and drain pipe around the inside of the cinder block wall. I want to put in new wall, concerned that TapCon or other hammer/gun attachments will compromise the cement cover over that pipe. Can I just use liquid nails?

Best Answer

I have found liquid nails on a few jobs in the past that did appear to work but is not code in my area. The 2x4 placed flat on the wall only needs an inch and a half to be code. The minimum wall thickness for a single story here is 6" and 8-12" on taller structures. Most modern basements were poured with forms that have straps or snap pins holding the forms from blowing out. These go all the way through so I don't think there would be a problem with Tapcon or expanding anchors. I have used both on my homes and jobs with no negatives. Tapcons will strip out if over tightened so I now use 3" long Hammer set expanding anchors. They are a bit more expensive but I have never had one pull out on studs or back planes for electrical panels.
