Is it coming in at the garage doors? We had that issue and my husband basically built a speed bump at the door. He used cap blocks, laid them the width of the doors, then covered and rounded them with a bit of ready mix. Just like that, the issue went away.
Can you change the grading around the garage to slope away?
The foundation level of your garage should accommodate a buildup of rain water around it or else water is going to flood in. You should be able to see your garage foundation above your ground level. The higher your foundation, the better chances your garage will stay dry. But detached garages, especially ones built decades ago, may have insufficient foundation height. Installing a drainage system to flow water away from your garage or building a garage with a higher foundation are the main options that can help you solve the flooding problems permanently.
Do you have gutters to catch and divert the water?
Is your garage floor cracked and the water is coming through from the ground up?
Are the eaves clear and the downspouts unclogged?
Is the drainage-landscaping-away from the garage?
Take a look at them and see if you have any of these problems.

Hi Lisa,
Higher the level of the floor inside the garage and fix a Threshold across the front of garage. If possible grade the driveway to run away from your garage. Best wishes.
See we’re the water is coming from in the rain ,then divert the water with bricks away from the garage you could dig a trench around the front and add gravel and the rain will just go in there into the ground.
If the entire floor is way too low, one can’t just mix up a few batches of concrete and trowel them down, sadly.
If this is the case and none of the above solutions are going to work,
then I would acid etch & clean the entire floor, rent a concrete mixer and pour 2” of concrete “topping” that’s made to go on top of other concrete.
It will need to be screeded to slope significantly to the door.
You’ll have to hire help for the screeding and it’s going to be messy.

You may need a French drain system installed from the rear of your home, around one or both sides of your home. You may also need a better gutter system with wider gutters and downspouts, and a means to divert that water a minimum of 10' away from your garage/foundation. Ideally, an underground downspout extension system could divert the water out to near street level.
Your situation may also require installation of a full width linear drain, near the garage door to catch any water at the front. This will require some excavation work, a great deal of 2B gravel, and some enginerring assistance to calculate the needed slope.
Hi! I would install gutters and route the run off to a drainage pipe setup. I would also consider diverting water away from the structure with French drains. Good luck and stay safe!
