Floor Drain Install in Garage

[Batteriesnare]

House we purchased recently has some drainage issues in the garage when a wet car is parked inside. Doesn't have a drain installed, and from my research it looks like a trench drain could be installed to then run to a collection point in the ground that needs to be periodically emptied (rather than attaching into sewer line). Has anyone done this and have a recommended installer, or other ideas? Thanks!

Some of the drainage issues could be due to the floor not graded correctly. You could do the drain, then have it go in to a grey water collection tank. I doubt it will be cheap fix. They'll have to cut and remove a section the concrete floor, for the pipe to be ran.

Are you thinking just a French drain down the center (or where ever your low point is) into a pit with a sump? Well, I guess you aren't talking about enough water to need a sump. Even the drain should be able to hold enough water until it evaporates. Might have moisture issues though I guess.

Exactly how much water you talking here. 20 gal. or runoff from wet vehicles? If it's just runoff, buy a squeegee and call it good.
The cost and labor to remove the water, will be thousands less than installing a drain. Concrete isn't getting cheaper, plus the time frame to actually get someone in to do the job.

I use one of these for the shop and patios, the monsoons will leave water every where

Better first check with local codes to see if you can do a floor drain in the garage. I know some areas do not allow for it.

I'm thinking on one side and along the inside of the doors (2 bays). It's an older house (built in 75) and is extended on one side (half bay, no door) as a workshop area. Challenge is, at least so far, water is running towards the half bay front and pooling in the corner Squeegee is the short term answer, but looking for a longer term solution. I've seen a few videos where something like this was installed, which is where the idea came from:

Yep, probably poor compaction before they poured the floor. Chances are it has dropped at the 'back' of the garage wall and the side walls too.
You might consider replacement or mudjacking settled areas .

A couple of ideas. Not sure what's on the other side of the wall but go with the flow and sending the water that direction

I've done some jobs where I ground a shallow trench to intersect and redirect the water.

Those gutters can be cut into existing concrete without repouring sections if you're precise about the cuts. Make sure to buy a common brand, I've had to replace some due to the grates being no longer produced

A sump with a pump cut into the pooling area is another rather simple option but requires maintenance occasionally.
