Water leaking into home up through the floor?
My house sits on a slab foundation in southern California. After a good amount of rain, we awoke to find puddles on the kitchen floor. Upon further inspection, our living room carpet was soaked through at the edges of the wall adjacent to the backyard. Our kitchen and living room are situated next to each otherr. We pulled up the carpet and found that the water seemed to be leaking in through the floor. Is this going to be a costly problem (dumb question)? How can this be fixed? Thank you!

Yes it could be costly. If you home is on flat land there is no where for the water to drain but into the ground. A drain around the hose could help if you have somewhere for the drain water to go. My guess is you had enough water to come up over the top of the slab. We have seen this here in Tennessee after we have had a lot of rain. A french drain around the hose will work but it has to have somewhere to go. I do not think you can run it out on the street! It could be diverted to a dry well but then again I do not know if they are legal in California. Your best bet is to get 3 estimate from 3 good contractors in your area. They would be able to help you more than anyone here.

Don’t have an answer for repairs. My only comment is to contact your insurance agent and see if you have flood coverage.

Buster bare with me here; my answer can go many places here with the limited information and I’m gonna have to assume a lot here. I’m going to assume you’ve lived here at least 2 or more years and this is the first time your home has had water coming in up from the foundation. Something has changed? New construction near by, i.e. neighbor has put in a pool, or a retaining wall, something that has diverted the natural flow of water? If not, turn off all the water in your home, make sure no facets are running and toilets aren’t filling. Go out and look at your water meter and besides the numbers that look like an automotive odometer? (in my case) or however yours is so they can read the meter. There should be what I call a tattle tale. It’s usually a little red triangle under glass. The numbers move to slow so look to see if this tattle tale is moving, wiggling, or even vibrating. If so you have a water line leaking somewhere between the meter and your home. If what I’ve described doesn’t match your meter have the water company come out and verify whether or not you have a leak. Something’s changed? If you have a leak and it’s uphill from your slab floor or under your slab floor then it could have your foundation soaked / saturated and now during a large rain the water that would normally migrate / dissipate to the water table is now added to the soaked foundation and the water is raising up and into your home. Should you find this to be accurate? The insurance company should pay for the damage of getting to the leak, foundation relieving if it has heaved up. Then repair the leak, put a french drain down both sides of the home. You’ll need the french drain going down the low side of your home to get rid of the water that’s already under your home asap because until your foundation dries out to normal levels you won’t be able to approach any foundation problems you may have due to the water. The insurance company should pay for the french drain going down the low side of your home because it will be required in order to dry your foundation out. This should at least give you something to investigate. Something’s changed to cause enough water under your foundation to raise enough to come in during a rain.
