I have a 7 year old garage floor (3-car wide) that is not sloped from the back of the garage (inside door to house wall) to the overhead garage door side. In fact it appears that it is highest in the center of the garage as water runoff from our cars runs to the house wall side as well as to the garage door side. I would like to figure out how best to resolve this and would like to do it myself if possible. There are some cracks but nothing major. Any thoughts on products or procedures that have worked for others?
Thanks in advance,
