Replacing the whole basement floor.
#1

I am in the process of replacing me basement floor. The curent flooring consist of a 1.5 to 2'' concrete slab. Their are significant warps in the floor which reqyuire repair. I plan on removing the current floor myself, and having the concrete poured by the pro's. Are their any general things I should be concsious of as I hammer away at my existing floor? For example, Do I need to wory about removing the conrete near the edge of the walls? How deep should I dig?

The reason you floor heaved, was that the concrete was too thin. When you have the new floor poured, you will need at least 4" deep. I think minimum code is 3' but even that is too weak. You can leave chips along the edge. But will probably have to take out a couple inches of dirt also. big job, good luck
