Lowering concrete apron

[DRH1175]

I am wondering if this is possible. My apron on my back garage has a slight slope towards my garage. Other than ripping it out and starting over is it possible to just lower the front to slope it away from the garage. Or am I best to rip it out and start over. The Knuckle head that poured it had his head up his arse. I am sick of my garage filling with water when it rains heavy. Along with my garage door always freezing shut in the winter. My apron is 4' x 44'

Do a search for Slab Jacking.

I've the same problem!! its a real task but it can be done! dig trenches under it every 4ft.put a 2x4-2x6 under each trench.then remove all dirt and grade it to slope you want,while the 2x4 0r x6s support it use a lever and folcrum to relift and remove 2x4 or x6s.

I did a search. I need to actually lower the front of the apron to put a slope on it. The back edge that meets the garage is at perfect height. I was wondering if there was a way to lower it for less money than just ripping it out and starting over. Thanks
