concrete slab topping
we are looking to overlay an existing concrete slab which varies in elevation due slopes to drains and from just plain poor workmanship originally. the deviation from a flat level surface varies from zero to 2" below the datum. please tell us about some product you have found would work as an overlay (epoxy would be a bit pricey)

what is thif for? a parking garage, concrete floor office building, ...
this is for an office floor  iniialls exposed concrete and later carpet

take a look at this stuff:
i assume you are in the us, and if so the product jae has suggested is the type you want.  in australia, the favourite leveling compound is ardit.  just be aware, all these leveling compounds are only for internal use.
