00:00

4 months ago this is what my drive

00:02

looked like and you could go down the

00:03

tunnel system from inside my house and

00:05

you would reach a dead end as there is

00:07

more digging to be done so we started

00:09

digging the drive but we realized this

00:11

was going to be much too hard so we got

00:13

the Digger in and made a huge hole oh my

00:16

god what have I done there is no going

00:19

back but what am I doing this for so I'm

00:21

building an underground garage linked to

00:23

the tunnels which go up into my house so

00:25

my DeLorean can rise up out of the

00:27

ground subscribed this is going to be

00:30

totally awesome this is the biggest DIY

00:32

project on the

00:33

[Music]

00:43

Internet it's getting

00:45

there right Colin what you been up

00:48

[Music]

00:50

to oh yes is this the year people when

00:54

the DeLorean comes up at the drive okay

00:56

welcome to secret garage update 3 now

00:59

then people that have been subscribed to

01:01

the second Channel thank you very much

01:03

it has passed a million subscribers

01:05

absolutely amazing you've been watching

01:07

all the construction some of the long

01:08

form videos of how this thing's been

01:10

built now today in this video I'm going

01:12

to talk about the design talk about the

01:14

wise cuz let's face it I've been doing

01:16

things in completely the wrong order

01:18

it's been making my life difficult as

01:20

well as the weather now up until now

01:23

this has been my cad model my cardboard

01:25

AED design as to what's happening what's

01:27

going on but there's a lot of questions

01:28

and a lot of people are obviously not

01:30

quite understanding the scope and the

01:33

full picture of this project so I think

01:35

we need in true Doc Brown style we need

01:38

a

01:40

mle do whatever

01:43

[Music]

01:46

he ground what El here is

01:53

a how cool is

01:56

this this is

01:58

brilliant

02:00

now sorry for the crudeness and it's not

02:02

quite to scale actually that is totally

02:04

not true it is bang on scale we got to

02:06

get you back to the future references in

02:07

hav

02:09

[Music]

02:15

you now as you can see this is the scale

02:18

basically 10 cm on here is 1 meter in

02:22

reality so I think that makes this a 10

02:23

to1 scale now unfortunately my DeLorean

02:26

I think is 18 to1 so it looks a little

02:28

bit lost never

02:30

need to find a bigger DeLorean model so

02:32

you can see where we're at we got the

02:34

tunnel sticking out down here just below

02:36

the house very nice and then basically

02:38

we've dug up to this little line here

02:40

that's what we've excavated so far and

02:42

of course the bit of room that we've

02:43

made is this so This bit here goes in

02:47

here that is what has been constructed

02:49

so far so here we are in that

02:51

beautifully fabricated steel room now

02:54

while I was doing this well particularly

02:55

when I was doing the ceiling that's when

02:57

I looked up and I thought there is a lot

02:59

of concrete going over the top of this

03:00

it is not just really thick but is also

03:02

really wide and at that point I thought

03:04

I better just get this double checked so

03:06

my design consisted of the steel room

03:08

set in the concrete with some vertical

03:10

steel joist welded to the side of the

03:12

wall mirrored on both sides and of

03:14

course across the top was some e of

03:16

bigger steel joist so at the Central

03:18

Point here the concrete was looking

03:19

about being 5 to 600 mil thick and of

03:21

course that across the whole thing

03:22

that's a lot of weight that is so had a

03:24

structural engineer check this this part

03:27

actually okay it's in the reinforcing

03:29

mesh application where things started to

03:31

differ right so here's Collins's rebar

03:33

he just slides that down into the

03:35

concrete for the floor slab which by the

03:37

way was a nightmare to put in we're not

03:39

doing that like that I'll get on to that

03:40

later but as well as that Mr structural

03:43

man he wanted the second one ride up

03:46

against the wall behind it now that

03:50

would have been okay I'll just slide

03:51

another one but no there's more

03:53

complications he just didn't want it

03:55

flat he wanted it bending and tying in

03:59

to that bottom floor slab so it Keys

04:01

into the bottom bit and as difficult as

04:04

this was to get in it does make sense

04:07

wish I can demonstrate with this

04:08

wonderful test now all the forces on my

04:11

walls are coming from the weight of the

04:12

ceiling the expansion of the clay and

04:14

The Rock basically trying to push itself

04:16

into the room now if you can imagine

04:18

this is the reinforced mesh in the

04:19

concrete when something is pushing

04:20

against it it's trying to bend it but

04:22

also as it bends it loses height it gets

04:25

shorter so basically what that's doing

04:27

is it's pulling on the top slab and

04:29

pulling up up on the floor and by

04:31

bending that rebar round you divert some

04:33

of those forces so they're not just

04:34

pulling up but they're pulling across

04:36

and then they're pulling on the whole

04:37

concrete slab going across the floor

04:39

Distributing that load even further now

04:42

we can calculate these forces quite

04:44

precisely cuz I had a geotechnical

04:45

survey done this is basically a dude

04:47

which comes out takes Rock samples and

04:49

sends them off for Crush tests and then

04:51

has this little twisty device which he

04:52

puts into the clay tells him How firm

04:54

the clay is tested it we're in firm clay

04:58

what's after firm firm can you get is

05:01

after firm is stiff stiff stiff after

05:03

firm very stiff then very stiff we got a

05:06

firm on we are now it's about 5 minutes

05:09

into the video and before you see me

05:11

struggle trying to get this bent rebar

surf shark they're a lovely sponsor now

06:13

let's see how I choose to bend this

06:14

rebar now despite only being 10 mil

06:17

thick rebar is pretty strong and very

06:20

difficult to bend so I fabricated myself

06:22

a little bending device which you just

06:24

slot on and it makes it very slightly

06:27

easier but the problems don't end there

06:30

now getting this round and under here is

06:34

going to be a bit of a peg trimming the

06:36

rebar trimming the Rocks getting it

06:38

stuck getting me stuck working in a

06:41

confined space this was a tricky

06:44

job now adding to this already difficult

06:46

job is the fact in an Ideal World this

06:48

stuff doesn't want to be touching

06:49

anything other than concrete doesn't

06:51

want to be touching the ground doesn't

06:52

want to be touching my steel room so as

06:54

well as trying to bend it and fish it

06:56

under the floor I need to hold it in a

06:58

position so when the concrete comes down

07:00

it doesn't shove it and move it all

07:02

around and get it in the wrong place now

07:03

we achieved this by welding pegs onto

07:05

the steel room and onto the rebar to

07:07

hold it into position and this worked an

07:09

absolute treat even with concrete

07:11

flooding round it it never shifted

07:13

anywhere and once it's all set we're

07:15

good to go with the next bit so we're

07:16

left with this about 400 mil of rebar

07:19

sticking out of the concrete and the 400

07:20

mil is important cuz every time we join

07:22

our rebar we have to go 40 times its

07:25

diameter if it's 10 mil of course that

07:27

gives us 400 mil boom so now we need to

07:29

bring another bit down and overlap it

07:33

and connect it onto our rebar but it

07:35

still has to not touch the room and then

07:37

of course after that we need a secondary

07:39

layer in front of that one now to attach

07:42

this rebar to the lower part there's two

07:44

common methods you got old school with a

07:46

tie and a tie wrap wrap it around hook

07:48

it on spin it until it goes tight and

07:50

then just fold it over or there's the

07:52

modern method one of these a tie gun

07:55

basically just put the Jaws over it pull

07:57

the trigger and it ties it automatically

08:00

absolutely fantastic saved me so much

08:02

time with the pegs we welded on to hold

08:04

the rebar in place removed we carefully

08:06

lowered the new rebar down into the

08:08

garage I proceeded to put it into place

08:10

tie it to our bottom bit of rebar I then

08:13

bent individual pieces to tie to our

08:15

vertical rebar to wrap around the corner

08:17

to form a continuous mesh then with the

08:20

secondary layer fitted and spaced off

08:21

it's time to fill it in with

08:25

concrete now it's very difficult to know

08:28

how much concrete you're going to need

08:29

so for this project we've been using a

08:31

volumetric mixer this is basically a

08:33

cement mixer which has separate Bays for

08:35

the sand and the gravel and the concrete

08:37

they come down a conveyor belt mix at

08:40

the entry port and then of course you

08:41

can use as much or as little as you want

08:43

and also you can make it as wet or as

08:45

dry as you want or you can change it

08:47

halfway through the process this is

08:48

ideal for our application to get it

08:50

flowing at the right consistency and to

08:52

the level we require that's all gone off

08:56

nicely as you can see in there now we

09:00

didn't form this whole wall in One

09:02

concrete B for two reasons the first one

09:05

is weight concrete is heavy when we were

09:07

doing the bunker we absolutely piled

09:09

loads of concrete down on top of the

09:10

tunnel and we noticed a very slight bow

09:13

forming in the walls so to mitigate that

09:15

we just distributed the concrete more

09:17

evenly but these walls are a lot taller

09:19

this room is a lot higher they're going

09:21

to suffer from that even more so we've

09:24

got thicker box section but also down

09:26

this side wall we put a load of 45°

09:28

braces to properly hold it up and if you

09:30

remember when I actually built the room

09:32

I had these plates of all the little

09:33

circular holes in so we're halfway up

09:35

they'll get knitted in so once it goes

09:37

off the proper solid it's good and now

09:39

the second reason is damp proof membrane

09:42

Now The Damp proof membrane doesn't come

09:44

all the way down to the bottom because

09:45

at this layer of the rock this is better

09:48

draining than anything when we dug the

09:50

tunnel anything below this point was

09:52

bone dry the whole time we've done it

09:54

any moisture or water that gets down to

09:56

here will just dissipate through the

09:58

rock but as well as this we want the

09:59

concrete to fill in all these gaps so

10:01

like properly Stitch it into the ground

10:03

cuz any stresses any forces any movement

10:05

pushing against the room the more it's

10:07

connected to its surrounding area the

10:09

better so bit of dprof membrane down to

10:12

there fantastic there's your second P

10:15

[Music]

10:18

boom I've got this great idea to get me

10:21

out of

10:22

here right we've got our rebar up we've

10:24

got our membrane down and we've got

10:25

concrete to here the last part we need

10:27

to do to complete these walls is to add

10:29

a horizontal rsj beam across

10:34

[Music]

10:43

here now this is to basically take the

10:45

expansion of the clay because this top

10:47

seam is in the clay when that gets wet

10:49

it expands it is going to push on these

10:51

walls with a lot more Force so that is

10:53

to basically keep the whole room level

10:55

and straight across the whole thing all

10:57

good and then we need to get some

10:58

rebound and attach it over the top here

11:01

to knit the two bits together and we do

11:03

this with these little Hoops which I've

11:05

had pre-formed very

11:09

[Applause]

11:14

nice and this isn't just to uh make it

11:17

look very nice cuz the whole thing runs

11:18

around nice and level does look very

11:20

good it's so when we do the rebar going

11:22

across the top which of course needs to

11:24

take all the weight of the vehicles it

11:26

all ties in and knits together so that

11:29

goes onto there like so then there's a

11:32

lower one which will also come

11:34

underneath those beams and the whole

11:36

thing will stitch in and that is where

11:38

all our strength

11:41

is so got my rebar walls formed then we

11:44

got a bit of shutter in shuted this end

11:46

off here just underneath the horizontal

11:48

bar filled that up with concrete and

11:50

that gives us like a bit of a boundary

11:52

wall and of course remove the plywood

11:54

you can see that looks very nice we've

11:56

got an extra bit of rebar which is going

11:57

to head over the roof as well then after

12:00

that we took all the lead off and

12:01

everything and it can expose the project

12:03

for the actual scale it

12:05

[Music]

12:12

is thank my

12:16

good it

12:19

time I have known known and that brings

12:23

us back to the future back to the

12:25

present day now I've been working on

12:26

this for about 3 to 4 months which is a

12:28

very long time but this was always going

12:30

to be the most difficult part getting

12:32

this all set out getting it aligned

12:34

taking the time to measure everything

12:36

cross reference it making sure we're

12:38

building this in the right place because

12:40

this has to be parallel with the house

12:42

the garage the garden and everything are

12:44

all funny angles and all go off at a

12:45

different tangent so I can't use them as

12:48

references so I had to use the house and

12:50

we're not quite under the house yet so

12:51

this was all have to be done off the

12:53

walls which we can't see from down

12:55

inside the hole so what's left to do

12:56

with this bit well first off the

12:58

concrete which goes down up to the

13:00

little boundary wall we've ped and

13:01

across the top of this rsj that's all

13:03

going to be done with a lighter grade

13:04

concrete and because it's so big it'd be

13:06

a victim of its own weight but we're not

13:08

going to cast that yet we're going to

13:09

wait till we finish doing the whole room

13:11

now then what is next Colin we need to

13:13

dig a bit more out but how much more

13:16

okay I hope this bit is going to clear

13:17

up a lot of the questions as to what

13:19

this project is all about where it's

13:21

going and where everything fits in so

13:23

the next dig we cannot dig a massive

13:26

hole as wide as what we've done before

13:28

because we've got the doorway and the

13:29

house to worry about if we undermine

13:32

this little door frame here and this

13:33

pillar here too much then we risk of

13:35

destabilizing that possibly having some

13:37

cracks forming the walls so we need to

13:39

dig up to about the side of the door

13:41

there and straight down but as well as

13:43

that we need to go a little bit deeper

13:45

as well now if I get my extra piece of

13:47

model

13:48

this is stage two so that is the next

13:52

bit of room that we need to for now

13:54

don't know if you noticed on all the

13:55

reinforcement that come down here and

13:57

everything there was all the bars

13:58

sticking out all the 400 mil bars we've

14:00

got that to build off so this bit is

14:02

going to be a lot easier cuz we're not

14:04

having to worry about where everything

14:05

is we're just extending the room now I

14:07

know what you're saying Colin why is it

14:09

going a little bit deeper well we've got

14:12

the car to worry about and how it gets

14:14

lifted in and out and where is that

14:16

happening that is happening here now get

14:19

the rest of the model I I can do this

14:21

that knock in the camera

14:25

this is the rest of the room it is going

14:28

to be big

14:29

[Music]

14:31

look at that this is the grand plan

14:34

people so the car will come up out the

14:37

floor here where's my DeLorean I've been

14:39

looking online for a bigger one can't

14:40

find one even the Playmobile one is the

14:42

same size as this the Lego one might be

14:44

fractionally bigger you will drive onto

14:46

the

14:48

drive this bit here will have a lift

14:50

mechanism and the whole thing will lower
