Is it feasible to rent a concrete mixer from HD, buy 70 bags of concrete and pour a 6'x21' patio extension myself? A buddy can help but I didn't know if that is too large to pour without it setting unevenly or something.

You can do it, but you’re going to hate your life.

Just pay the small load fee and get a concrete truck. I’m assuming there is enough room to get the truck back there so you can tailgate it.

If your set on doing it yourself and not getting a truck then id definitely recommend getting more help. Id have one guy constantly mixing and bringing concrete with 2-3 guys placing and finishing.

Concrete is one thing that can really get away from you quickly especially if your not experienced with it. Worst thing would be trying to run around doing ten different things while the concrete is setting up on you in the mixer.

We already have cracking issues in our driveway so I'm trying to avoid bringing a truck in.

Another option is to rent a Georgia buggy and get a truck to bring some concrete. Can also ask the concrete company to add an additive to make the concrete not set as fast to give y’all some wiggle room and peace of mind.

just rent the boom truck so its all done in the street

those booms can reach over the house if need be

the concrete will be unfinished and dry in one corner while you are still trying to fill the rest of the form. no way in hell a slab of that size can be poured by hand unless you hire a 30 man work crew and rent 4 or 5 of those mixers

A boom truck for 1.5 yds? Just hire someone to do it. Will be MUCH cheaper

Thanks for all the advice. Looks like I'll be hiring someone. Maybe I can find some foreigners needing some extra work.

Don't even try with bags with a area that size. You will not have enough time to work the concrete.

Anything over 20 bags is a no go. It will be cheaper and way easier to get a concrete truck in.

after watching a guy pour a slab for me...no way in hell i would ever attempt this on my own

leave it to the professionals.

What about using concrete molds(link below)? it takes a little under 1 80lb bag to fill one 2'x2' mold. The concrete truck route does not seem like an option here. a doing this by hand has to be cheaper than a pavers company, right?

If you want to eliminate cracking over anything I would form it to where you have three 6'x7' segments just run a 1/2" expansion board between each and pour yourself. That'll allow any settling to be independent of each other. Make sure you've somewhat compacted the area but if you're pouring a 4 in slab and it's only for residential use any settlement would be unnoticeable.

It'll also give you the option to pour it in segments if it's a rectangular area.

Don't do it.

I tried to do it with 40 bags. Turned out like shite, and my back was killing me.


70 bags of concrete is almost 3000lbs. You gonna put that on a trailer, b/c that ain't going in the back of your truck in one load.


I guarantee you by the 20th bag, you're gonna want to say frick this, but you can't, b/c you have to work very quickly. holding up a 40lb bag high enough to dump into a concrete mixer for the 70th time is going to kill you.

get a concrete truck to come by and go rent one of the buggies that can transport large quantities.

I have done a lot of this. Break it up over a couple of weekends. Form up and complete one section at a time. Do it in three sections. Its not hard, youtube will help you to know how to finish it. Be sure to vibrate the forms after you pour to get out an air pockets. Do a brushed finish (careful to not go to deep).
