What does it cost in your area to have a concrete crew come in and form,
pour and finish concrete for a slab for a shop? I'd pay for the concrete,
and rebar. Just a per square foot price for the labor?
Funny timing. I just got quoted today for a 17' x 25' x 6" seven bag mix
pad with rebar in front of my main shipping door. They are also going to
grade the area of the parking lot to the street 100'x100' and place 30 ton
of stone. The pad will have a steel grated trench drain in front of the
door tied into a basin. The parking lot in that area is 2' higher than the
shop floor and we have had water in the shop. They will also take care of
the 18" foundation of an old out building in the way. All this for $5,300!
I thought it would be twice that.
That doesn't answer your question...I'm just thrilled with the job getting
That's really funny. I've been getting ready to get some bids for the front
of my shop. It will be just like yours except for the drain. Right down to
the old foundation in the way and sloping the grade. :)
Today I find out our big forklift threw a rod, see my glote post. With a
new forklift, a pad and a level lot...loading trucks won't be such a PIA!
ANOTHER problem permanently solved, only a few thousand more to go.
Good luck with your job!
There's no reason why a standard 2x4 form won't work for a residential driveway.
Don't be like the klutz who poured the back patio in one of my houses 8" thick.
It took me days to jackhammer that out when I went to build a deck and I ended
up building around part of it.
Everything matters. You need to start with a good compressed base made with the
right material to allow drainage, prevent frost heave and not settle. You need
to have a proper mix. That means the right agregate material and the right
amount of cement. You need the pour done at the right temp and before the mix
goes off. Finially, you need enough "cream" with the finishing so you don't get
Even then, I probably missed a few things...
In a similar vein......
A friend of mine was building a new shop for his race car, and he had the
surveyor lay out a perfectly level floor on which to set the race car up.
He had the slab contractor come in and told him that everything was set the
way he wanted it to be, and to just pour the slab.
When he got home from work, there was his beautiful new slab.
The contractor said everything was going along fine until he discovered
that the surveyor had, apparently by mistake, NOT included a slight slope
"You'll be happy to know I caught it in time, and took care of it for you."

Service to my country? Been there, Done that, and I\'ve got my DD214 to
I put in a concrete driveway and back yard patio/hot tub slab 2 years ago.
The soil/gravel mixture around the home was put in place while the house was
being built. It was partially compacted by "time" (12 months/4 seasons) and
by various machinery driving on same. Immediately adjacent to the
home(~4'out from foundation) the soil was compacted in 2 ft lifts. For the
remainder of the 30' one side/65' other side (a 90 o curved driveway) I
added about 4" of what they call "roadbase" around here (1" minus
gravel/sand mixture). I formed up 4" high 3/8" ply strips, double
layered/screwed to 3/4" on pegs making the top of the 'form' 5" above grade.
I rented a vibrating plate compactor and pummeled the roadbase (it was
conveniently raining at the time). After that, I ran 3/8" rebar on 2'
centers throughout. I'd called a concrete crew that worked on the house
next door to placxe the concrete. They arrived at 6AM (while we stared at
a dark gray cloudy sky..Will it Rain ??) We decided to go ahead..the
concrete trucks (2) arrived and they laid about 6 yards of 3000# concrete
(IIRC) They put control joints at about 6' centers and did a "light broom"
Following that, we took another load behind the house with a concrete line
pump and did a 250 sf slab with 3/8" and 1/2" rebar (under the hot tub
area) and they finished it the same way.
My cost..a lot of physical WORK..about $ 400.00 in rebar, $ 300 for the line
pump and another $ 100 for forms, $ 150 for the gravel ..40 bucks for the
compactor, 10 bucks in rebar ties = $ 1000.00 The crete was about $ 1000.00
My cost for the concrete crew 45 cents a square foot.. Yes $ 0.45
They (3 of them, one left after 2 hrs) were here for about 3-4 hours and he
took $ 500 cash for the 1100 sf job.
So, I was quoted $ 5000 for the whole job by two different contractors. My
cost was $ 2500.00 with a lot of PREP work.
The good news: after 2 years of 4 seasons: HIGH 104 o to Low -10o.. No
cracks at all. About half of the control joints have done their job.
You can get it at a reasonable cost if YOU do the prep work. If not, be
prepared to pay double for "Them" to do it.
