Water pooling in Garage
fsetterberg

When I park my car in the Garage with snow or if it is raining out the water pools in the middle of the garage and I HAVE TO SWEEP IT OR SHOVEL IT OUT. can I put in a easy drain to get the water out.

Yes, you can put a drain, but it may not be so easy.

Garage floors are poured with a slope, to help with getting water out. If your garage floor lets water pool, than it has a flaw. However, if you cut it, install a drain to the outside, you will need to consider the acceptable slope of 1/4" per foot length, or the water won't drain. You will also have to deal with the steel re-bars in the concrete.

In simple English: the outside has to be below the garage floor grade enough to allow water flow out.

It's easier and cheaper to squeegee the water out by hand.

I'd be inclined to set up some wedges and cut some saw kerfs to drain the water OR cap the existing floor with a sloped cap of concrete to redirect the water. Problem with the concrete is the thin leading edge won't hold up.

There isn't anything that my skills and your money can't achieve.

Sure you can have a newly sloped garage floor. What is is worth to you in whole dollars? More than the occasional puddle ?

McGyver moment -

What about installing big, powerful fans to blow off the water just like the exit of a car wash ?

Install a laser beam when broken by the approaching car turns on the blowers until your car has passed the beam so as you drive through at the desired speed you dry your veehickle.

I'm liking this idea. :cool:

I've done this and it works but you have to keep the floor clean as the narrow kerfs tend to fill with debris easily. Start shallow then go slightly deeper and deeper toward where you want the water to drain. Dry-cutting diamond- edge blades for skilsaws are cheap now and anyone can do this. Just go slowly and use a good dust mask; silica dust is very bad for your lungs! The depth at the far end has to be at least the same depth of the pooled water at it's worst or slightly more. A stick broom used sideways or an air hose makes cleaning the kerfs easy.

I've seen so many garage floors which were poured level except close to the doors that I could almost make a living at draining them. The lack of common sense in my business these days makes me sick. There's no need for perfect levelness here so use that fact to your advantage and have a slope- even a slight one will be enough.

It appears the original poster has never checked back with any info about how the water gets in.
I've seen glue down rubber thresholds advertised to keep out water and debris from getting under garage doors.

Hence the wedges to control saw depth as you go. A jig of some sort may work better, just depends on how long the kerfs need to be.
