40 year old garage floor needs help

[mrramsey]

Hi guys... new to the forum here. I am looking to do some renovation to my garage. I was actually trying to build a second one but the city was making it too difficult. I am left to try to create a small wood shop in my 2 car garage of ~420sf. The old concrete has a few issues. There is some pitting, a few cracks ~20' or so, and a slight 'hump' for lack of a better term, at the center of the overhead door. This creates a gap on the right side.

I really do not want to replace it unless I have to. I looked in to a few professionally done options like naturestone and epoxy. the naturetone looks cool but the cost is stupid, epoxy is affordable but my problem with both are that they are hard surfaces. I am also concerned with dropping any of my wood working tools onto a concrete surface. My thoughts at this point lead to PVC tiles.

I will have shop tools on one side and my wife will still park her car on the other, at least in the winter. I guess my biggest questions are:

1. Is there any prep work I should do to the existing floor?
2. Do I need to worry about moisture from melted snow seeping below the tiles (No drain in floor)?
3. How well will they conform to the shape of the floor (regarding the hump)?

I think maybe you have a little more going on here than you think. My suggestion would be to have a professional come in and give you an estimate on repairing the slab. If nothing else it will give you a better idea of how bad this slab is and then you can make an educated decision on how to move forward.

The large crack going from the frame to the expansion joint and huge amounts of daylight are definitely troublesome.

Yes, that slab raised in the middle needs some work.

Well I got some quotes for the work. By the time I pay for the leveling ($750) I am still left with cracks to repair along with a fair amount of spalling. There's also no guarantee that it totally addresses all of the issues at the door. Couple that with the expense of fixing the spalling and coating the floor or covering with tiles and I will add another $2k at least. A new slab is going to be between $3k-4k.

I am leaning toward the new floor at this point.

I live in Syracuse NY cold and salt everywhere my 40 year old slab was bare, cracked and spalled everywhere. Use a two part epoxy for cracks, Ardex cd fine for spalling after you get your slab fixed.

I have decided to go with a new pour. The cost will be $3700 to tear out and replace.

I'd insulate while you can and consider putting in pex..

Definitely insulating. Unfortunately in floor heat ain't in the budget.
