REPAIRING CONCRETE FLOORS

REPAIRING CONCRETE FLOORS


Should I take. . . should I remove this shirt from yesterday was the same one. Nah, it’s not necessary. Okay. Yes, is this recording? Hello my friends this is Bahiano with Bahiano Reno. In this video, we’re gonna
show you how to repair some concrete flooring here. We just had to break this floor to put in some new pipes underneath, and now we’re just gonna repair it. When you have the sand compacted and
the floor compacted we just put a vapor barrier—6mm poly—on top of
it to seal the moisture. And after that
you’re good to just pour the concrete. With the poly you just go underneath everything like you see here. We have a wall here as you can
see the poly just continues to the other side. So this wall would be protected against the moisture. And here we have the extra poly right
underneath the 2×4. You see my hand go through. And then you have this other
piece of poly that the concrete would not be touching the wood.We have a vapor barrier right between the the 2×4 and the concrete itself.
And this is all separate. This is the vapor barring for the wall going around
the 2×4 and there is the vapor barring between the floor and the concrete. I’m just gonna make sure that I would have this sealed, like right against the pipe as you guys can see. This is sealed right against the pipe. I’m just pushing the poly right behind the pipe so that I would put the tape real tight in there. Okay, there you go just nice and tight. I
just put the poly right underneath the old concrete. The reason that I’m doing that I want this thing to be real tight and I would use
this big glue on the old concrete. I’m just gonna use this glue that way it helps
to hold the barring and makes better contact between the older and the newer concrete. This helps to hold the old concrete to the new one. This is why I have this exposed, because I want to do that.
And try to seal it as much as we could. Here we have a joint from the poly so
we just used duct tape which works very good. This is sealed. Very good, like you guys can see around the drain is all sealed. Moisture is not something that you should play with. It damages
your house and create mold. Once you are doing the concrete just make sure that you have all the drain, all of the holes, all covered. Because if concrete goes inside your drain then it’s a headache. In this case I’m
just using this green tape because this one would be easier to remove once we’re
done. It’s not very good idea to use this one because this one is very sticky
and would be very hard to remove. You guys can see for the toilet there I just
put a piece of poly and taped around it. I just make sure right now that I have concrete underneath the old concrete. Just push it in and bang it up. Make sure that it’s nice and tight in there. The consistency of this concrete is three part sand and one part cement and the water as you like. And we
use some mortar additive that is a glue that help make the make it stronger. So
this is a very strong cement here. Yes we coat it with the additive glue, like you guys can see, and then we’re gonna mix some
more on the cement to do small patch like this. It helps to hold better the
new cement to the old cement. This is how the product looks like. You
can see it’s still wet in there. I’m here just straightening up the concrete a little bit, then when it gets hard we just do another straightening up. I have the line of the wall I just follow
from the old concrete to the line of the wall. Because this wall is leveled so I know how high I need to go. Just following the bottom plate of the wall is already leveled with that side so I just follow it and make it straight with the other side of the old concrete. Nothing to crazy, just straighten up as much as I can with the
piece of wood and then I go with the trowel. Take some reference for this. You see
the concrete is about there. Compare it with the 2×4 so we have about 3-3.5″ of cement down here. Just try to compact it. All the time we bang on it we compact it tight, this is why we gotta keep moving on it all the time to
make it compacted. We use the wood since it’s wider than the trowel so it would be
straighter with the wood and the trowel. This way we have a good line. But with the trowel is you have a good hand you can do a good job. But it leaves some depth on the
cement. If you have a piece of wood like this, you just gotta grab your reference point just remove the bigger parts. This one here is too a little bit too
soft to work on. It’s good when you give like about three hours and then you come back and straighten it up, it already starts to
harden and then it works better that way. Yeah once you use the wood, if it’s something that needs to be finished up really good just come back after 2-3
hours and then you can do very good finish on it. After that we’re done just put a new floor on top and we’re good to go. Hello guys this is Bahiano here again. It’s been about 24 hours. We’re back here, our concrete repair and this is pretty
much done in how it looks, so now it’s been 24 hours this is still soft. This
conflict is hard enough to step on but it’s still soft to scrape so if you don’t
feel very comfortable the way it is you just grab a scraper drowel, something like this. Yeah a floor
like this is good enough to put like a hard wood on top or tiles or other
finishes, but if you need something better this needs to be skim coated a little
bit better. In this case, this is what we need in here. And here we have
the drain. I’m just gonna open it right now. Just gonna clean up a little bit around it so you guys can see the cement is sloped towards the drain. It is important to keep it covered because you have work to do here and I just don’t want
mess to go inside this drain yet. Because we still have a lot of work to do and I just need to have this protected. It’s very important that sand and other
stuff doesn’t go inside this drain. Light stuff is okay because the water would
carry it on, but not heavy stuff like sand or cement around the pipe. Like you guys
can see we just need to do a little bit scrape and it’s good enough for this
this room. So this is the new one, this one here’s the old one, I can clean up a bit for you guys to see. It’s just like I said very good, like you
guys can see the new and old is very straight and besides that there’s another
thing that you can do if you wish to remove some high spots that you don’t like. You can use a grinder. Just grind it off is a little bit dusty but it does work and make it straight. Yes guys, here I’m just gonna put
some more screws. This concrete is still soft so screws work. The reason I’m going to do it is because I need to cut this door plate. Usually you
use pins to put on the hard concrete but this one is still very soft so I just don’y
want to to do it right now. I’m just gonna put some screws we’d go through the wood to the concrete which would keep the wall in place because we just had a full 2X4 in there and the plate just goes straight to it the door to keep it on place. So right now I need to cut this guy. This is just an old-timer 12V Dewalt screw gun. Yeah I just have
it kicking around and it’s working good for many years. Battery’s still strong. I’m just gonna cut the plate. After we cut the plate we check how’s the concrete, we need to keep it all one level. Let’s see, I’m
pretty much using an old blade because this is gonna touch the concrete. There you go. Looking good guys, you can see it’s a little hole there behind the bottom plate. the poly got stuck there and didn’t let the concrete go all the
way down, so this is what we’re doing here. We’re just gonna remove all this
stuff do a little bit more repair and we’re good to go. And then we’re just gonna add a little bit of cement to the floor and we’re good to go. You guys can see the concrete patch/concrete repair is
done. Looking good, I’m happy with it. We’re just gonna do like I say like a
little bit more repair and we’re good to go. Thank you very much guys for watching this video and we have a great content coming up so keep your eyes open. And if you have any questions about the concrete patch work, let us know, or any other questions about any video that we do. Just let us know. Make your comments, we love comments.
