Anyone lay their own concrete?

I've done concrete and helped many pours im not afraid to tackle it myself with a couple laborer buddies and i run heavy equipment so everything should pan out just might not have the most perfect finish but ohwell its gonna have derby cars and oil stains all over it anyway except the back half will have my nice cars
You sound like me a little over 40 years ago. I did a garage slab with help from a lot of friends. Maybe too many friends! They all had their own ideas of how to do it. Long story short, when the truck comes to pour, you better have it figured out, Cause there's no time for planning anymore. We got it done but now everytime I look at it, it's a reminder, I wished it would have turned out better. Now, flash forward to about five years ago when I had my floor poured in my pole barn for a really good price. It came out beautiful! I couldn't have been happier. And then the first cracks started showing up a year later. And those cracks have gotten wider and deeper now and they move with the change of seasons. And now everytime I look at it I'm reminded again of my mistake. Cheap isn't always good. I checked out this guy's work ahead of time. But it was fresh work and looked beautiful and it didn't have time to crack yet. The bottom line is I screwed up twice and I thought I was doing the right thing. Be careful if you contract it out. Check out their older work not their newer work.
If you do it yourself I would get a pro by your side, even if you gotta pay him for his knowledge. Good luck, I think you can do it right if you think it through!
