Pole barn concrete

Okay...Got the second quote today and it was for $2300.00
Went ahead and made the deposit of 50% they should be out next week to do the pour. Quote includes 10 gauge wire reinforcement and 4000 PSI mix. This is for a hand trowel finish. I just didnt want to bother getting more quotes and postponing the pour since I am held up until it is done. Hopefully this is a good price. This quote was about a $100 more then the under the table guy however they are including the wire in the price and they will take care of everything including stress cuts. Now I have to decide if I want to shell out several more hundred dollars on underslab insulation. If I do I will probably go 1" thick.

Don't bother pouring more than 4-5" concrete on your floors for your application. Anything more and you're just a philanthropist for a concrete supplier. You'll probably get a calander from them with the $1,000 extra bucks you waste.

I've been pouring concrete in garages for 25 years and my own shop has only 4-5" of reinforced concrete in it. I park my fully loaded IH dump (35,000lbs on a single axle dump) in the garage many times with no cracks anywhere. 1/2 my garage is on fill, but I compacted it properly and never have cracks. I did get a shrinkage crack in one sidewalk once. I think I got some watery concrete from the bottom of the mixer barrel. Ticked me off.

For normal useage, it's not how thick you pour the concrete, it's how you do your prep work. Compact the ground tight with a rammax, install vapor barrier and do a 2'x2' grid with 1/2" or 5/8" rebar with 3500lb fiber concrete and you'll have a tough slab that'll last decades. Fibre is made of fiberglass mesh that will take more time than we'll be on earth to deteriorate. WWF (welded wire fabric) mats or rolls can and does rust. It is better than fiber, but when you use rebar and fiber, it makes an unbeatable combination.
