re: Extend concrete patio - cost

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.
