In this video I want to give you a tour of the Rhino Carbon Fiber Crack Repair System
0:17
using this mock-up here. I'm going to be using the Epoxy Injection to fill and strengthen this crack and then
0:24
I'm going to be applying some Carbon Fiber Reinforcement over top. So I'll lead you through all the steps and you can see if it makes sense for your jobs
0:32
Normally if this were a typical crack we'd be cleaning the sides maybe with a wire brush
0:37
perhaps grinding it out. But since it's a mock-up we can go right to the repair
0:41
Now these are the injection ports. This is what lets you inject the epoxy into the crack and each one comes with a little cap
0:50
You have to take it off. You're going to need that cap later to plug up the hole but for now I'm just going to
0:57
be installing two ports. One at the bottom and the other some distance away
1:04
In practice you'd install them about 18 inches apart. Here's the two-part anchoring epoxy paste
1:12
It's just a standard kind of dual-sided injection gun and this is the port
1:19
It's got baffles in it so that it mixes the two parts of the epoxy so that it hardens
1:26
outside the cartridge. So you can reuse the cartridge, continue to use it if you don't use it all in one go
1:41
When you get down to the nitty-gritty of this repair you probably want to put on some gloves
1:45
to protect your hands. Now this epoxy doesn't cure all that quickly so you've got lots of time to work
1:56
You basically just want to get some of the anchoring paste on the outside
2:02
It's important that you keep that middle hole open and I find that a skewer or some kind
2:08
of little wooden sliver thing helps because it makes sure that it stays open and it also
2:15
helps to hold it in place while we do the rest of the work
2:22
More anchoring paste now goes on the crack. The purpose of this is to contain the epoxy that we'll be injecting later
2:32
That's different stuff than this and we need to contain it otherwise it's not going to
2:37
fill the crack. It's just going to ooze out. We don't need to go very deep with this
2:43
We're just creating a sealing skin over things. You want to go over the lip of these injection ports because you don't want that to leak
2:56
or to go anywhere. We want it completely sealed in. Now it's time to inject the crack with the structural epoxy but you see that the dual
3:10
cartridge has different sizes here so I have to change one of the plungers
3:16
I have to remove this and replace it with this smaller one here
3:27
The tip of the nozzle snaps into the injection port. I've pulled out the sticks that were here and I'm just going to pop that in
3:50
Now the idea here is that you just go slow and steady until you can see epoxy coming
3:57
out the top. That's why these injection ports are done in pairs and a certain distance apart
4:13
The epoxy has now reached the top port. I'm going to put a plastic cap in here
4:28
The whole crack is completely filled and the epoxy is not just taking up the space
4:34
but also binding this concrete together. It's porous enough that it's going to get a really good grip on it but there's going
4:41
to be more that we do to make it even stronger than this. Epoxy is great stuff but it's also very messy and there's not much that can clean it up well
4:50
So I recommend you get some of these Rhino Tough Wipes. They've got a solvent in them that does a really good job on epoxy
4:59
I don't know anything else that would work as well but we've got a little bit of ooze out here
5:03
This has got a solvent on it and it's also textured so it's a bit abrasive and it mops
5:12
up this stuff quite well. Now it's time to grind all this off and to prep the surface for carbon fiber application
5:20
So we just start by knocking off these ports and then going at the surface with this diamond
5:30
cup wheel. Before I put the carbon fiber on the test blocks I want to point something out
5:49
There are three different kinds of carbon fiber fabric here. This is called the vertical and that's because you can see the bands of carbon fiber run
5:57
this way. They're held in alignment with threads that run this way but it's strongest in this direction
6:05
This one is what's called the horizontal. So same idea except the bands of carbon fiber run this way and the holding threads run this
6:12
way so it's strongest in this direction. And this is called the bidirectional and you can see it has a tightly woven network
6:21
of carbon fiber bands in both directions so it gives overall strength
6:26
Now I'm applying the epoxy adhesive, the stuff that's designed for securing the carbon fiber
6:35
I'm going to be just getting it on the surface here and then rolling it out
6:43
I want to make sure that the masonry is completely saturated so I'm going to have to go over
6:47
this a few times in order to completely wet the surface
7:03
The idea here is that I bond the carbon fiber with the epoxy that I've put on but I'm also
7:10
going to put on some more too because I want this to be completely saturated with the epoxy
7:18
because this is where the real strength comes
7:33
When this is all set up it's going to be stronger than the concrete blocks itself
7:39
The blocks will break before this bond does. Different versions of this same Rhino carbon fiber product can be used for specialty applications
7:49
This banding is reinforcing a failing concrete corner. Here you can see the bowed wall kit which is used to stabilize a wall that is bowing
8:00
inward from soil pressure. These are called stitches and they're a carbon fiber product for extra heavy duty reinforcement
8:10
of cracks. You set one of these into the crack across it and then fill it in with epoxy as part
8:17
of an extra heavy duty repair. So we're all set out here to do a stress test of this Rhino carbon fiber crack repair system
8:29
These are the two blocks that you saw previously in the video. I've got the bidirectional carbon fiber on here
8:36
On the other side there's the unidirectional so it should be strong as we pull it
8:42
I've got some straps in here a quarter inch thick. They're going through the joint line and then we've got a tractor here and a tractor to
8:51
my left and we're going to see how hard we can pull on this thing
8:55
Now I have also filled the blocks with concrete because I was afraid that these straps might
9:02
just pull through the webbing on the concrete block. So we're all full and we're ready to put some stress on this
10:02
I thought something was going to break here
10:12
Maybe the blocks, the center part but as you saw there's absolutely no breakage at all
10:18
It's flipping around like I don't know what. We've bent the straps
10:24
You saw the wheels spinning. We just can't get it apart so I think it really is true what they say that this stuff is stronger
10:31
than the masonry that it reinforces
