I used to use powder-actuated fasteners, but only over newer slabs . . . the older slabs would "volcano" and push the plate upwards. Concrete nails are almost impossible to drive with a manual hammer. I really like the tapcon method.

[@LevelUpFraming]

Agreed! And yes, tapcons work great 👌🏻

In my jurisdiction you can also use stainless steel nails to connect the PT plate to the studs

[@LevelUpFraming]

Thank you for sharing! It’s good to know about stainless steel nails as an option.

Holmes on homes would have a plastic sheet barrier that would go between the treated base plate and the concrete floor. This was a buffer bc concrete absorbs water 💦 and even treated wood 🪵 will be damaged with water!! especially where the nail enters the wood and concrete! The treated wood is only around the outside of it and when you drill through and don’t use some type of sealant your making an easy access bridge for water to absorb through the concrete up through the nail and in to the untreated wood.

sil gasket wiorks too

Hello! Yes, concrete naturally absorbs water. This is why it very important to have treated lumber wherever it is touching concrete.
However, basically all treated lumber is treated all the way through the board. You do not need to touch up the cut ends. The above video is a little confusing because the lumber we are using is stained on the outside. This is how the manufacture makes it, so it looks better for visible uses (like decks). But the inside (and therefore cut ends) are also treated and will not rot if exposed to water from time to time.

Any tips for framing a floor over a concrete slab?

Thank you for watching!
We are making a video about every skill it takes to frame a quality house. So subscribe to see it when we post the floor framing.

Nice video man. I'm not a carpenter, but I knew that the bottom plate had to be pressure treated; however, a lot of people said I was wrong because a foam gasket was also needed. Any thoughts about that?

[@CDArena]

Foam gasket will help a little, but sucking water out of concrete thru capillary action is not the only problem; what about a burst pipe in the house, or dripping condensation, or water spilled on the floor, dog pee, dishwasher leak, washing machine, hot water heater....
Any water which penetrates from outside, or standing water inside will cause untreated wood to get damp, and rot or worse yet attract termites.
Use treated lumber on concrete.
Foam gaskets are better for preventing air leakage on an uneven floor.

Thank you very much for the encouragement!
It is not necessary to use a gasket on interior walls. We have only done that once for a customer request.
Certain soil types and lot locations can hold more water, therefore it is recommended that you put a taped moisture barrier under the entire slab. Water and minerals can soak into the slab, affecting flooring, trim, and even dislodging tile.
Basically if a treated plate is not enough, you have bigger problems to worry about. So a continuous moisture barrier under the slab is recommended in those locations.

I've only used the foam gasket under the sill plate where a framed floor sits on the foundation.
