My garage floor (not the one in my avatar) has a low spot that creates a puddle from snow melting off the cars in winter. It's about 5 feet in diameter and about an inch deep. I want to fill it before covering the whole floor with Racedeck. What kind of concrete or other product should I use? I don't care what it looks like as it will be covered. It needs to bond well and handle a feathered edge. I assume I don't want self leveling as I need to maintain the overall front to back slope of the floor.
