This video will provide you with a little more information about whether or not you should consider using framing plates that will be installed before or after pouring a concrete foundation. Both have their benefits and drawbacks. Keep in mind that structural engineers and local building authorities might not approve the use of wet setting framing plates for a variety of different reasons.
Great video. I learned something new.
Glad you enjoyed it and thanks for watching.
I do mine loke that for tornado shelter
I've never seen that before. I can't see the sense in it.
Sounds good.
I love that he brings it up. There may be situations where it would make sense, but if not at least you have more ideas of what works and why
You just put your plate on top of the bolts and smack the board with a hammer which marks the bottom for drilling As long as the bolts are plumb they will fit perfectly.
The main issue I see with pre installing the plates is sealing, moisture wicking prevention and termite flashing in areas that require it. Isn't it code to put a moisture barrier under the wood?
If you pre assembled the plate and insert after troweling the top, there shouldn't be voids around the bolts as long as the mud hasn't set too hard and you jiggle them in. I have always seen them inserted after floating the top anyway, and done it that way myself. You do have to go around and check them though until the mud starts setting as they can settle too much if placed early.
You definitely made it sound easier than it might be if there are larger anchor bolts for hold downs and all of the anchor bolts aren't at the exact same height, but I've used your hammer over the bolt on top of the board method before and it does work.
@@gregvancom I imagine the larger they are the more they want to sink, making pre attaching them necessary. I have never had to set anything larger than 5/8in 12in long j-bolts. How are you dealing with the sealing and moisture problem though, nothing? Just direct contact? Or do you pull it up after the concrete sets and add the other materials. Some could be fastened to the bottom of the toe plate in advance, and the idea may still work.
@@court2379 If you're referring to how do you seal the bottom of the wall framing plate space in between the top of the footing, then you can use almost any sealant, but if you're looking for a waterproof seal that is never going to leak, then I don't think I would have a recommendation.
@@gregvancom No, I believe code in my area requires anything that contacts the concrete to be moisture resistant, which the wood is not. The reasoning that moist travels thru the concrete and would cause accelerated rotting of the wood (even treated wood). Also it causes expansion which could crack the finished walls. So putting a foam gasket under them has been common for years, though they probably use something more advanced now. Finally a caulk or tape would be used to do the final air seal between the plate and concrete applied in the corner where they meet. Addressing any locations where the concrete and wood don't match well and full compress the foam.
@@court2379 I definitely didn't understand your question. First off, let us know where you're from, state or country will be fine if you don't mind. I've never had to deal with a material used underneath lumber to prevent moisture from absorbing into it, but have seen the gaskets and even metal use before, but whether or not this stuff will actually last, I don't know.
In my experience you are in a hurry to pour before the weekend, let it set up over the weekend, get out of the dirt and start framing floors, not drilling plates.
Exactly
