two days have passed since we last taped
0:07
videos and the reason why is we needed
0:09
the concrete to get nice and hard and I
0:11
also did another really important step
0:13
before we finished the job and I want to
0:16
show you what I did look down
0:18
here so this is where the black top
0:21
patch is going to go so that we blend
0:24
new black top you know into the trench
0:26
drain right here well after I took off
0:29
the form arms from the concrete it was a
0:32
pretty deep hole there I had some extra
0:34
concrete I mixed it up and I placed it
0:37
in here and made it very rough on
0:39
purpose I also made sure that the
0:42
distance that has to be filled in is
0:44
about 1 in maybe a little bit more and
0:47
the reason why is because on the written
0:50
instructions of the black top patch it
0:54
tells you that it really only wants you
0:56
to put it in about 1 in at a time so
0:59
that's going to be be perfect and a 1-in
1:01
covering here because I have the solid
1:04
concrete underneath it is going to be
1:05
more than enough black top patch in the
1:08
next video I'm going to show you how to
1:09
put the black top down it's time to put
1:11
in the black top patch it's really kind
1:13
of fun because we're at the end of the
1:15
project and it's really satisfying to me
1:18
to get to this point because it's going
1:20
to be a job well done and you're going
1:21
to have the same success at your home
1:23
let's talk a little bit about the actual
1:26
black top patching material you can buy
1:29
it ready mix
1:30
and here's what it looks like it'll come
1:31
in tubs like this it can used to come in
1:34
bags and it's really a neat material I
1:37
mean it's very
1:38
flowable you can see it actually kind of
1:41
moves on its own I mean you know it's
1:43
and here's what it is so it's small
1:46
pieces of rock that have been coated
1:48
with asphalt cement the same type of
1:51
asphalt cement for the most part that's
1:53
found in regular black top but they have
1:55
to put it in a water Emulsion so that it
1:59
stays you know pliable inside this
2:01
bucket otherwise if it was like
2:03
traditional black top that's probably
2:05
put down at your home that comes from
2:07
the asphalt plant with just asphalt
2:09
cement the reason it flows out of the
2:12
dump truck and they can pave it and put
2:14
it down is because the asphalt cement is
2:16
hot it's usually about
2:18
375Ā° and that makes it very liquid like
2:21
hot maple syrup so what happens with
2:23
this material is after you put it down
2:26
that water that's surrounding the
2:28
asphalt cement starts to evaporate
2:30
leaves just the asphalt cement behind
2:32
and it starts to get hard now one of the
2:35
differences is and you can see that here
2:37
is that this material is made up of very
2:39
kind of small stones they're really
2:41
really pretty small they're only about
2:43
as big as that stone there but some
2:45
regular black tops have bigger stones in
2:47
it like here's a big one here's a big
2:49
one here's a pretty big one and the
2:52
bigger the stone that's in the asphalt
2:54
the stronger the asphalt is so this is
2:57
going to work really well at the edge of
2:59
the drive driveway here I just would
3:01
never pave an entire driveway using
3:04
material that had small chips like this
3:06
let me show you in the next video
3:08
exactly how you put it in now I want to
3:10
show you how to actually put the black
3:13
top patch material in I use you know
3:15
like a wide putty knife it's really a
3:18
drywall uh you know taping blade you can
3:20
see the the asphalt emulsion cement
3:24
right there and I've even got some on my
3:26
fingers already it'll come off with
3:27
mineral spirits if you get this on your
3:29
clothes it's going to be really tough to
3:31
get off so wear old clothes when you do
3:33
this I just usually scoop some
3:36
out like
3:37
this and you just just dump it in
3:41
there and watch how it flows when I put
3:44
it in watch this you can put it in and
3:46
it'll just kind of flow on its own see
3:48
that how it just moves it's really kind
3:50
of a neat
3:51
material and you want to put it in a
3:54
little
3:55
higher than what you want the finished
3:58
uh surface to be
4:00
because you're going to use a a
4:03
compacting tool or you're going to use
4:07
maybe a block of wood or something to
4:10
hammer it down to get it smooth and to
4:12
compact it in in my case I actually have
4:15
a a real tamper here it's really really
4:17
a nice tool but you can kind of see what
4:19
you do here you try to keep it off keep
4:21
it off of the the
4:23
grate and you just kind of continue to
4:26
put it down you really can't hardly make
4:28
a mistake
4:31
and once again read the written
4:33
instructions do what it
4:35
says you know they don't want you to put
4:38
this in any thicker than 1 inch and if
4:40
you have to fill it in deeper than 1
4:42
inch they want you to do it in half inch
4:44
increments you know puts half in in
4:45
compact it put another half inch compact
4:47
it until you finally get to the
4:50
top so let me put a little bit more in
4:53
here and then I'll show you how to
4:55
compact
4:58
it I I've got some of the black top
5:00
patch material in place I've already
5:03
compacted some of it over here and you
5:05
can see this area right here is not
5:08
compacted this is a tamping tool it's
5:11
made out of solid steel and I've got a
5:13
nice black iron pipe to add some extra
5:15
weight to it and this is a really handy
5:17
tool to use for this type of job I have
5:19
to keep the the tamper you know at the
5:23
same angle I want the black top to be
5:25
but you don't have to apply that much
5:27
pressure and you just Tamp it
5:32
to make it nice and
5:35
smooth and that's really there all
5:37
that's all there is to it it's not that
5:40
hard to do now sometimes it'll stick to
5:44
the bottom of it like that so what you
5:46
want to do is scrape that
5:48
[Music]
5:50
off and if you want
5:52
to you know you you put a little bit of
5:54
filler in here to where it was maybe
5:58
uneven and you can oil the bottom of
6:00
this as well this plate if you put a
6:02
little bit of lightweight motor oil on
6:04
it it'll make sure that uh it won't the
6:07
asphalt cement won't stick to the plate
6:09
watch
6:20
this that's going to come out pretty
6:23
nice it's going to look really good
6:24
we'll tape a final video once we're
6:27
completely finished so you can show you
6:29
the finished trench drain okay the
6:32
trench drain's finished and it came out
6:34
really well I'm really really happy with
6:36
it let me give you a tour of it and I
6:38
want to tell you a few extra little tips
6:40
that we did that uh really are you know
6:44
can save you some time and trouble check
6:46
it out look here so you can see it's
6:49
finished here's the concrete you know
6:51
here's the drain itself we patch the
6:54
black top and over here to my right you
6:57
know and to your left the these are some
7:00
rocks I added where the water's going to
7:02
flow down and it's going to hit these
7:04
rocks they're kind of jagged and
7:06
hopefully the water's going to slow down
7:08
a little bit and then it'll come down
7:10
into the trench drain here any of the
7:13
water coming from that direction any of
7:15
the flow here across the driveway is
7:18
just going to come right down this ramp
7:20
and go into the drain and remember this
7:23
part of the concrete it's sloped down so
7:26
the water is not going to flow up here
7:28
and uh come up to here cuz this here is
7:30
higher by 3/4 of an inch than the metal
7:34
grate finally down here at the end you
7:37
can see the pipe leaving the trench
7:40
drain and I left the pipe exposed so
7:43
that you could see it we're going to
7:44
cover it over with some dirt but the
7:46
pipe when the water comes out of the
7:48
pipe it hits those rocks and the purpose
7:51
of those rocks is to slow down the water
7:55
and slow down the force of it so it
7:57
doesn't cause erosion over there
7:59
because now what we've done is we've
8:01
actually concentrated the water in the
8:03
trench drain and it's actually going to
8:05
have more energy than it did as it came
8:08
into the trench drain because it's more
8:10
water faster so it's very important to
8:12
put those rocks out at the end of the
8:15
pipe that exits your trench drain I hope
8:18
you learned something it was a fun
8:19
project I know yours is going to come
8:21
out just as good as mine I'm Tim Carter
