Extend concrete patio - cost
Posted on 7/14/18 at 4:03 pm
Posted on 7/14/18 at 4:03 pm
Looking to extend my patio by about 360 sq ft. 4" slab.
2 estimates I have gotten seem pretty steep unless it costs higher than I thought for this type of job.
What sort of price per sq ft should I expect on average? Attached is a rough drawing.

If you don't like the price, do it yourself. I think I can safely assume this is in the back of your house, so, form the area up, dig it out, put in any reinforcing wire you may want and it's then just a matter of getting the cement in place.
I would recommend renting a couple Georgia Buggies and get a few friends over to spread it, then it's just leveling and finishing it and letting it harden.
But it does pay to know what you're doing in the first place, like adding just a bit of pitch to allow water to run off. I hate slabs that have low spots and hold water.

Too many variables. A lot has to do with the access from your front yard to your back yard for pouring concrete, digging equipment for dirt and other materials. For instance will the dirt be dug out with a machine or with a shovel? What is to be done with the dug out dirt.
Can concrete be poured out of a truck, a georgia bucket or mixed on site. Same for sand placed under the new slab.
Do you want dowels installed between the old and new slab, if so they need to be drilled in the existing slab.

It's a small patio slab. Dig that shite by shovel and be done with it. It all depends on the level of the original slab to the lawn as to how much dirt has to come out.
I think it is safe to assume concrete can't be poured directly out the truck by chute since it is likely in the back of the house being it's a patio, so Georgia Buggies are best to use in this situation unless he and his friends know how to drive a 4 cu. ft. regular wheelbarrow full of wet cement-----probably not.
The only issue for the DIY is if they want to drill and attach to the existing slab-----and if it's just a 4 inch thick and a stand alone slab, so it should be good to go.

I am generally a DIY type person but have never done concrete. The point you made about the low spots is why I'm hesitant.
You are correct that it is in the back yard and we will not be able to get a truck back there.

If it helps I just got a quote to do exactly what you are doing with the #1 patio for $1200. Thats everything too. They clear out grass and form it up, pour and finish. Mine was 170 sq ft. They also have to wheelbarrow the concrete about 60 feet.

I had an 18’x10’ poured 4 years ago, turnkey it cost me $1800

Roughly 5 yards of concrete: materials will probably run you 125-150 a yard as a non contractor. It’s been going for $110 a yard for 4K psi recently though with an account.
Pump truck minimum of $800, although it will probably be line pumped so call it $400
Misc materials ~ $500
Crew cost ~$750-$1000
All in, if you pay over $3500 you paid too much.

Consider doing it yourself. You dig out the area, frame it up, put some wire/rebar in and then mix and pour it. It will look fine for your back yard.

$7/sf with decent access. Muice has probably been ripped off a few times with his engineering degree if he's even considering paying the $10 psf he's talking about.

What were the quotes? If two quotes came in from two different contractors and were similar, then they both saw issues in getting to the patio areas. Labor is the number one cost on these things. If they can get a little excavator back to them to dig them out in an hour and form them up, get a truck to it and pour them then you are probably looking around 1500 for all of it. If you are going to have to pump it and spend a day digging it out by hand and another day pouring it then you will be staring at between 2500 and 3500 I would think.

Decided to DIY with the help of some friends.
Any recommendations on places to get a truck (if we meet the minimum)? May not meet the minimum on just the patio but I have some additional work I may add in which could make it worth it.
Also, what is usually the minimum on a truck?

Just make it bigger somehow. I don't know what the minimum is at all, just saying.
How patient are the trucks? Say you have 3 wheel barrows will they sit there and wait while you wheel the loads from the front of the house to the back to dump?
Posted on 7/20/18 at 11:26 am to jmorr34
They will just charge you a short load charge
So a typical truck holds like 8-10 yards
If you need less than that they will charge you a short load charge

I widened my driveway 6 months ago, which took about 5.5 yards of concrete.
I dug it, framed it, and placed the mesh. A hired a guy to finish it. He charged me $1600, which included the concrete.

2850 to 3300 depending on some things.

Consider renting a Georgia Buggy if the truck can’t get to the patio. They run around $120 from AAA Rental. Had some guys I know pour a patio for me a couple years ago and I rented one for them. It saved a LOT of time and manual labor.

I don’t know what the prices are where you’re at, but I own a landscaping company and we pour quite a few back patio extensions (4 coming up in the next 2 weeks)
what you have to remember about pouring concrete this time of year, is that you need a lot of man power. If your running wheel barrows, you need 3 guys for that, then you need another 3/4 ( depending on slab size) to be finishing and working the concrete. The concrete will be able to be walked on within 3hrs of it being poured.
Use #3 rebar and dow into your old patio. 16 inches centers for the rebar.
How much elevation change is there? Any? Do I need to bring in dirt and a bunch of form boards or do I just need to weed eat the grass down and take 2 inches of dirt out? The former takes a lot of time.
What finish? Broom? Stamped? Smooth?
Anyways, I’m pouring a 20x12 that will require 4 yards of fill to be brought in and compacted and I’m charging $3500 for it.

Not the OP, but I've been looking at extending my patio and this is really helpful. I'd be looking at something closer to 8x10 and only a couple yards of fill dirt to level it out. Would that be closer to $2000 or would the labor spend likely take it closer to 3?

If you know a guy that can finish concrete somewhat decent I’d do it yourself. I did mine 21x15 and a small misc pad for $1400. That’s stone bottom, visqueen, forms, reinforcement, Georgia buggy, etc.
