uneven basment floors

have a problem with a poor quality poured concrete floor. it was poured in sections and is very uneven. is there a simple poured solution? i do not want to limit the ceiling height. i can go up to 2".adheasion is a problem with most of the sections. the concrete is chalky and has little to no agregate. can build a sub foor but due to the poor leveling shimming will be tedious any ideas? the space is about 18/18'

 

Their is a product that is called self Leveling Concrete finisher which will be a solution for your problem. In my experience the product still needs to be leveled. A squeegee, a float and a trowel will be needed and you might try a small section to start to decide whether you want to DIY or call in a pro..........You might be better to post this in the masonary forum for more replies......

 

We had the same problem, uneven floors, very low ceiling. We live in Northern Ohio and I found a dealer in a product called "Nature Stone". It almost looks like pea gravel or natural colored aquarium stone. They mix it on-site with a clear, resiny concrete. Hauled in buckets to basement and spread 1/2 to 3/4 in. thickness. It leveled our bsmt. floor w/o sacrificing head room. Lifetime transferrable warranty, too. You can sweep, mop and vaccuum it, looks kind-of like carpet from afar. Many car dealers have installed it in their showrooms in our area, people use it outside for driveways, walks and around pools. Hope this helps~
