You have a major problem. concrete is not water proof (liquid or vapor)or really even water resistent. If you look at a concrete pool or tank, a thin plaster coating provides the water proof layer - not the concrete. Your best bet is to remove the concrete, lay down a real water proof layer and reinstall the concrete. You can put so called water proof paints/materials on the cement, but they will only last a few years. In the mean time, you will have completely rotted the wood framing that supports the concrete slab.
Wood water sealant or a good coat of paint that fills all the cracks. Don't forget to caulk the edges to keep water from running into the walls. Waterproofing may not protect again serious spills or overflows but could minimize ceiling damage on the first floor after a small leak.
Because there is a leak in the pipe of the water main.
First, you need to determine if you have a leak anywhere in your home. Check to make sure that your faucets, toilets, showers, hoses, ice-makers etc are not using water. Once you have determined that nothing visible is leaking, look at the water meter. The leak Indicator is a small triangle or star on the face of the meter, and if it is moving, even slowly, you have a leak somewhere. If you turn of the shut-off valve (often near the ground in a closet or near the hot water heater) to close it, and the leak indicator stops, then the leak is on a supply line to a fixture in your home. The shut-off valve often appears to go nowhere. It comes out of the wall, an perhaps splits off prior to going straight back into the wall or slab floor. If the leak indicator does not stop when you close the shut-off valve, the leak is on the service line into your home, and may or may not be under your slab, but is definitely under the ground. Movement on the leak indicator usually means a good deal of water is leaking, and you should see water coming from a wall or perhaps out of the floor. If you have no visible water, and constant movement on the indicator, a slab leak is a good bet. A leak detection company can help you find it, and get it repaired. More information us available at our blog for slab leak detection. It has more information on how to find slab leaks, what are slab leaks, and how to pay for slab leaks.

Leak on drain line above floor level
I have a water leak under slab concrete and it is coming off the walk into my yard. How do I get to it to fix it without breaking the sidewalk?

Water may leak onto your above ground floor after a heavy rain due to issues such as clogged gutters or downspouts, damaged roof shingles, poor sealing around windows or doors, or inadequate foundation drainage. It is important to identify and address the source of the leak to prevent water damage and mold growth.
depends on how much water, but in all probability, yes
Probably have a leak in the heater core>
Replace the hose.
There is obviously a leak in either the firewall/cowl area or the window seal.
Are you running the air conditioner? If the drain line is plugged, it will leak water (condensation) onto the passenger side floor.
Probably there is a leak in the wall it just doesnt come through the drywall. Reason why it isn't going to the first floor ceiling is the 2nd floor wall stops on top of the 2nd floor plywood so it will run down the inside of the wall and out onto the floor. You sure its a plumbing problem? Sounds more like a roof leak check out the roof above the wall where its coming out from under. Could be bad step flshing or nail pops whatever will let water in .
Dry up the water. Take the car to a car wash and spray it good around doors and windows. If a leak is not visible then check the floor during rain storms while driving to see if water is coming in through a leak in the floor.
sometimes window liners tend to leak.
