Hi, I’m Bob Smith from Home Remodel Workshop.

So you decided you’re going to go ahead and frame those basement walls in or put those walls down onto that concrete surface and it comes time that you need to anchor that treated plate down to the concrete. There’s a quick simple way of doing that. I’ll show you how to do it. Let’s get to work.

What this is called is a split thrive concrete anchor. I like to use 3 inches long for anchoring 2x4’s down the concrete. What it has are there little flukes that are pre-made into it and this nail is hardened so that when this thrives into that concrete, it just compresses it like no other. It wants to hold its form and it holds awesome. Whenever working with hard nails, they don’t have the tendency to bend; they more have the tendency to break off and split shoot off like a little bullet. Always make sure you wear eye protection.

You’re also going to be using a hammer drill and have a tendency to be loud. So you also got to make sure you to protect your ears. You’ll need a framing hammer, and just a simple drill with a quarter inch wood bit. Once you have your line down where you know where you going to want that wall to go, I like putting these anchors about every 2 foot on center roughly except for obviously on the doorway openings, if you’re going to cut that later. I take my quarter inch bit and somewhere towards the center of the hole, or the center of the wall plate, I like to drill that hole with a quarter inch wood bit.

Once you have your quarter inch holes drilled with your wood bit through your wood plate, making sure that you put on your eye and ear protection, what I like to do is take a hammer drill with a concrete bit for a three inch split drive. Always like to drill my hole a half inch deeper than my split drive that way if there’s any dust or debris in the hole there still has plenty of rooms at the bottom before it hits the top. So I put this piece of tape on here as a stop. Now you take this quarter inch hole here where you drill with a wood bit. Make sure you move this over to the line. Make sure it’s exactly where you want and you drill right through the plane and through the concrete until you get down to that tape. Now once I’m sure I’m down to that tape, I’d like to plunge a bit in and up to try to clear out some of the dust down the hole. And I go ahead and wipe that excess dust away so that it’s not clogged enough to hold it later on.

Simply tap your split drive into the hole, get it down through the plate and you can feel that it reached the concrete. It will line itself right back up to where it was. Get your hand out of the way. Making sure your eye protection is on. Now go ahead and drive that split drive. Now if you drive that split drive down just a little bit below the surface, let’s say when you come through here and your wall studs in, unlike other anchors, you could put your wall stud up right over top of that split drive and it’s not going to be in the way. Just to show you the example on how well this hold, make sure you put this on the line and in the right place before you drive them in.

I’m going to go ahead and try to pull this plane out say I made a mistake, driving under that plate with my ripping boar, lift it up and as you can see the plate can give up but the anchor doesn’t. Now if I put your pry boar on this or whatever to try to pull this up, I’m probably going to blow out a big chunk of concrete. So to make sure that I don’t have that happen, again wearing your safety glasses, safety protection, tap the split drive side to side like this and because it’s a hard nail, it will have a tendency to want to break versus bend.

So after you tap at side to side a few times, it will break off. So there you go the split drive. Pretty much a way of assuring that your wall plate stays anchored down to the concrete exactly where you want it. I’m Bob Smith with Home Remodel Workshop.
