My garage floor is leaking . It is 4 sections of concrete and where they come together, water is coming up there and I have some cracks in some of my garage, and water comes there also. Is there something I can repair all of this or do I need to get a professional?

I'd say you need a professional to find out where this water is coming from. You may a broken pipe under there.

Since there is almost no where else for the water to be coming from it must be coming from the ground around the garage. First make sure that gutters and down spouts are clear and working. Second be sure that you have splash blocks under down spouts or they are pipe to carry water away from the house or garage. Next make sure that grading around the garage is such that water runs away and does not soak into the ground immediately next to the house. The worst case scenario is to have to dig around the garage down to the footer and install drainage pipe. If the water cannot be drained away, a sump pump will have to be installed to pump the water away.

Granted you could have a broken pipe but it would be rare that plumbing would be under a garage floor. You could check this by making sure that no water is being used and check your water meter (or just wait for you next water bill)

I don't see the "panic" in your post, so I am thinking it is a small amount of moisture/ water. Was there a moisture barrier put under the concrete when it was poured?
