I have water coming into my garage

Sounds like you've tapped into a natural water source J. How many people would love that? Two things to try if you decide you aren't in love with it:

1) make sure all the land in the area is sloping away from the garage. Make sure gutters are working and downspouts flow away from the garage. If that doesn't work:

2) dig down below the footers, lay in stone and perforated pipe draining away from the garage. Called a "French Drain".

One of these will fix the water problem. Lots of instructions for building the French Drain are available at the end of a Google search.

It sounds like it may be coming from the ground. You may need to address drainage around the garage.

Check to see first off cracks on outside foundation. Then check to see if ground surrounding home is graded away or sloping away from home. If foundation shows no cracks to the eye that's interesting but it could be that you have cracks on garage floor allowing moisture up. If grading is towards home instead of away then it needs to be regraded. Generally speaking you can do if your handy by building up ground around home so that it slopes away but look on YouTube because you need a certain pitch for best results you don't want it to high and you need to add plants to hold in place. If garage has cracks you can fill then with products at any big box store but make sure that cracks are not large because then you will have to get a professional. Generally you actally clean out the Crack and apply product. They also sell paint to lock garage floor and walls just like for a basrment.

It most probably is a broken pipe under the garage floor. There are special plumbing companies who can pinpoint the point of leak, open up the floor and fix it. Make sure you get a warranty for the job
