All right, we have all of our character stones framing out our waterfall.
The next step is to find that speciality spillway stone that all the water's gonna
make its action off of.
I'm gonna get into a tip right away.
Let's say I have this rock, as our spillway stone.
Now notice its flat top, and this it has this cut, and then a down cut.
If water was coming off of this stone.
It would literally roll off of this cut, and fall off of this piece right here.
Now, if I spin this rock around with this back cut or
negative edge, the water would come across the flat top,
and literally fall uninterrupted all the way into the pond.
It's a pretty cool look and that's the vision that I had for
this particular waterfall, the negative edge.
Now, this particular spillway stone, I tripped on it in the landscape when we were
pulling all our rocks around. I saw it immediately.
Saw the negative edge back cut.
I pulled it to the side and said hey, I'm gonna save this for the waterfall.
So the next step is for us to place this, hide all the plastic from this,
from the faceplate attachment that we did.
We'll put some foam in there, to control the water to come all the way over the spillway.
We're getting ready to do that.
I'm gonna show you step-by-step how to do it.
[SOUND]
All right, I'm gonna totally admit it right now.
I really lucked out with this rock.
As I said, I just stumbled over it, but it just barely touches both sides, and
it's locked into place.
I've got to be a little bit
careful here with it.
[COUGH] I'm gonna put a little bit of weight here, because it has a pretty decent bite
right here, it's kind of barely hanging on this side.
So, I'm gonna put a little bit of weight on it on this side, to help lock it into place.
And as you see, this rock is set back, it doesn't interrupt my opening.
And I'll come through.
See, I gotta block this hole off right here.
See this hole?
A lot of water would be lost out there, so we're gonna have to block that off.
I found this interesting guy.
He'll sit right in there.
And I'll show you how we'll foam that little section in.
So the water, a lot of times I'll take this spillway stone, and
I'll set it right up to this height right here.
Whoa, don't move.
I'll set it right up to this height right here, and
the water will just come straight out even, and fall off.
But, this is an interesting effect when it rolls off of this guy, and
then it negative edges off of this.
So it'll be kind of a double effect.
So, we gotta get through here, and hide the rest of this face plate.
That's gonna work nice.
Let me see what other rocks I have.
Yeah, that's very cool.
You see how water is gonna come off of this, and it's gonna come out farther and
fall here?
So, I'll have water falling here and then back, I'll have water falling here and
then it will come off in this little curve, and when I begin to foam,
I can just put gravel up in this section here and hide everything out.
I've got to climb up here and check on this guy.
Yeah, I think this is looking pretty cool.
All right, I'd say we're ready for the foam gun.
So this is pretty much the rough end.
We've got it roughed in.
I see some voids back here.
I'll need to put gravel down there.
We've got some voids back here.
But other than that, I'm gonna grab the foam gun, and
we'll start foaming this guy in right now.
Okay, so we're ready to begin foaming.
I've got my foam gun close by.
And if you'll notice this, this crack right here,
we're gonna lose a lot of water right here, so of course we need to address that.
We have cracks in all along the way, water would of course,
wanna make its way right there.
The next tip is you notice I have some gravel right here, and I have some dirt right here?
I have these reserved so I can fill cracks, and I can cover foam, and
this is close by, so when I start to do my foaming, I have access to it.
So one thing I wanna say is, a lot of times I'll come in and I'll,
I'll fill this with a little bit of gravel.
Fill that void a little.
And then, let me check something out here.
So, I roughed it in of course, and now I wanna just tweak it a little bit.
Okay, so I wanna fill this void with a little bit of gravel, so
I don't have to waste as much foam.
Set this guy back down into place.
[SOUND] I wanna leave room for some foam.
[SOUND]
So, what I'll do is I'll put a light bead in here.
[NOISE] Whoa.
[SOUND] Now,
I wanna let that harden off just a little bit, before I put anything else in there.
Otherwise, it'll just collapse.
Okay, there are some voids in this, in this area that go straight down to nothing.
Now, you see how I have this roughed in?
I'm gonna pull this off gently.
Set it to the side, hold this guy off.
Now I pull this guy out, we have a pretty big opening right here, but
what I'll do is, I'll just do a, see how I kind of closed the gap with that.
Close the gap all the way over there.
Then set this guy in place.
And then I'll spray a little more foam back in behind it.
So, water can't pass underneath it.
[SOUND] The next piece.
[SOUND] Fill in a little foam,
and then I'll come back behind here.
Fill that up.
Find my last piece.
[SOUND] Now it's still wet.
So, we can move it around a little bit as it's setting up.
There we go.
And then I'll fill in the crack, with some foam.
Not that it would ever get up that high.
Okay, so all those layers have foam in them.
We'll touch that.
Still see.
It's hardening off.
Now, this, I don't have any gaps that lead to nowhere, like this one.
If I push through there, it falls all the way to the bottom.
But this one, I take that little bit of sand.
[SOUND] I can cover that up.
It's gonna dry gray anyways.
But, it's nice to not see it at all.
[SOUND] Now this guys getting a little.
It's expanding. It's called expanding foam, so
I'll break that down a little bit like this.
Cuz it's drying off.
Still gonna let that harden off while I come back here, and foam some of this side.
[NOISE].
All right, see these, these lines right here?
I'll point at it with my gun.
Right here, water will escape through these cracks.
Water will escape down through those areas.
And what I'm gonna do is, I'm gonna put a small bead of foam right here, because I want
all the activity to be on the surface, and I don't wanna lose anything from the back.
So, let me put a little bit of foam here.
Some foam down this line.
I won't lose any water back there now.
I'll let that harden off and then I'll put a little dust in there,
and then I'll come back and fill in the rest of the cracks as well.
So the foam's starting to hard off a little bit.
It's not sticking to my finger anymore.
What I'm gonna do is I'm gonna push it down in there a little bit.
Create a little space.
So, if I start dropping rocks in there, they're gonna stay there.
So, that's my next tip I'm gonna show you, so we'll push this down a little bit.
Now, if I put rock in here now,
the rock might wash off when the water movement starts happening.
So the next trip I'm tip tip I'm gonna show you is,
I'm gonna come through here, I'll add a little foam.
Cuz, I don't wanna see this lip right here from the destination spot.
So, I'm gonna add this foam like so.
Then I'll come through here with some rock,
now it won't fall through the void.
[SOUND]
This cobble will help hide the gravel, I mean hide the foam.
[SOUND]
You still might have a little expansion come out.
So, we'll keep an eye on that.
If anything starts to pop up, we can break it off or push it down.
We'll lose a little bit of this gravel when the waterfall turns back on.
[SOUND] But, that's the way to hide all of the, foam.
It's nice to not see that foam.
[SOUND] So we'll let that harden off.
And I'll just work in all the fine little details.
[SOUND]
This little crack right here, I wanna address that.
If water comes off here, it could work it's way under that rock.
And I'll lose some of the activity that's happening over the spill way.
It'll be coming back here.
So, I'm going to address this by adding a little bit of foam.
Get this thing set up.
[SOUND] And add a line of foam here.
Keep that water from coming back.
Come in this crack as well.
I don't wanna lose any water down that section.
And I set this rock earlier, but I don't think I like it.
I think I'm gonna pull it off,
cuz if I set it here then the line of water is here and here.
But, if I pull this off I'll have this little interest point here, water falling back.
Water falling here and then water falling here in this curve.
So, I'm gonna pull this guy totally out.
And I will just fill in this crack with some smaller gravel back here.
We'll add some dirt to this while it's still wet.
Now, I can add dirt to this right now even when it's totally fresh.
Because, I, I didn't do that on the top part because,
I didn't wanna dirt to force it down and fall away, cuz I had some holes back there.
But, since this, I'm just pressing it underneath that rock.
I can add it when it's fresh, and I'll have good adhesion.
It will stick really well.
This dirt.
And help disguise it really well.
In this corner I'll probably just put a little gravel.
[SOUND] Like so,
now this void, we're gonna fill this in.
[SOUND] And once again I got this little line.
If you can see this little line under this rock.
I probably wouldn't lose much, but I don't wanna lose any.
I'm gonna put a little bit of foam on that crack there.
Follow it up with a little dirt.
Doesn't take a lot.
And then this crack, just filling that in.
Now, if you'll notice you don't see that rock anymore that I pushed under there,
it was kinda just a.
That-.
That was just to help fill the void.
So, I didn't use as much foam, and now what I'll do.
[SOUND] Is I'll come through here,
push a little gravel in there.
And then throw some sand up in there.
You'll have to keep an eye on that, because sometimes,
the foam will expand out and come off.
When we rinse everything out.
That dirt will go away.
So, it's gonna be a neat effect.
We'll have a little bit of extra water movement coming over the pebbles,
then it'll roll off this guy.
And you'll get most of it, you'll notice this rock right here,
is a little bit taller, so you won't get much water coming off here.
It'll be more raging through here, opening up.
And becoming softer as it comes over this spillway.
So next thing I wanna do is I'm gonna spray some foam in, back in deep in these cracks.
And back in behind here.
To help lock this rock into place.
Because, it's kind of suspended over there, cantilevering out over the pond.
[SOUND]
We have the spillway stone completely foamed in.
Remember these couple tips and tricks that we did when we did this.
Rough everything in, have some rocks close by.
Have that small gravel pile next to you, and a little bit of a pile of dirt or sand, so
when you put that foam in there, you can help disguise it really well.
If you have any questions on what we did today, of course I want you to put them in
the comment section, cuz I'll get to each and every one of them.
I'm Eric Triplett, The Pond Digger.
Thanks for watching.
