If you want to know how to stop water from coming up through your basement floor, you’re in the right place. This article has everything you need to know, including why water is coming up through your basement floor, how to prevent it, and how to stop it.
How To Stop Water From Coming Up Through The Basement Floor
The only way to stop water from coming up through the basement floor is by installing a drain tile system to collect rising moisture.
- Drain tile system – There are two types of drain tile systems: interior, and exterior.
- Interior drain tile – An interior drain tile system is placed underneath your basement floor around the perimeter of your foundation walls. This system uses a perforated (filled with holes) pipe laid in a bed of washed stone. This pipe collect and redirects rising groundwater to a sump pit.
- Exterior drain tile – Just like an interior drain tile, an exterior system uses a perforated pipe laid in a bed of washed stone. But, this system is laid outside your foundation walls. This is beneficial if you don’t want to remove any drywall or concrete in your basement.
- Vapor barrier – A vapor barrier is a thin polyethylene sheet that’s wrapped around your foundation walls. This will prevent moisture from seeping through your basement walls, channeling any water into the drain tile system below.
- Sump pump – A sump pump is a fixture that sits inside a sump pit. Once water is deposited into the sump pit from the drain tile system, the sump pump will eject it from your home using a discharge line. The discharge line transports water at least 20 feet from your home in order to prevent further water seepage.
Why Is Water Coming Up Through The Basement Floor?
The main reason water is coming up through your basement floor is due to something called hydrostatic pressure. This is when water accumulates in the soil outside your basement walls or floors and pushes against them. Water can weigh around 60 pounds per cubic foot, making it a very heavy force.
The most notable place water enters through is the cove joint. The cove joint is the space between your foundation wall and basement floor. Your slab and wall were poured separately, and that’s why this space exists. The only way to counter water seepage through your cove joint is by installing a drain tile system.
How To Prevent Water Coming Up Through The Basement Floor
You can prevent how much water comes up through your basement floor by controlling how much moisture saturates your soil. Here’s how you can do that.
- Add a French drain to your yard – A French drain is a below-ground pipe that collects water that pools in your yard. These are very useful in preventing water buildup and puddles.
- Clean and extend your gutters – Gutters should not be pouring water too close to your basement. Otherwise, water will saturate the soil near your walls and floors. By extending your gutters at least 20 feet away from your home, you can stop water buildup. Also, remember to clean your gutters as often as you can to prevent water from pouring over the sides.
- Grading (sloping) your property away from your home – If rain is draining toward your basement, water could saturate the soil near your walls and slab. You could grade your property yourself, but we recommend calling in an expert.
Is Water Actually Coming Up Through The Basement Floor?
There’s a chance your basement floor might be experiencing “sweating.” Sweating is when condensation sticks to your floors and walls, developing wet spots. This may look like water is coming up through your foundation floor, but it’s actually just the air in your basement. Here’s a simple way you can test whether or not your basement is “sweating.”
- Tape aluminum foil over damp spots in your basement.
- Wait one day.
- If moisture forms on the outside of the foil, water is condensing from the air.
- If moisture is forming on the inside of the foil, water is seeping through your basement floor or walls.
Covering your walls with a vapor barrier and installing a dehumidifier can help counter condensation in your basement. The vapor barrier will catch moisture and transfer it to your sump pump, and the dehumidifier will regulate the humidity in your basement. This combination also works great if you have a crawl space foundation instead of a basement.

Hello Tracy! Unfortunately we do not know anybody in that area. Sorry!
In wet/rainy seasons is it common for water to be under basement floors even though there is no seepage into the basement? My 1969 home has an exterior drain system with 3 small foundation holes to allow accumulated water to drain into a floor drain and then into a he city sewer system. The exterior drain system appears to function properly.
However, after removing some basement concrete flooring for remodeling a basement shower & toilet. With a temporary low area under the slab for the drain plumbing remodeling, water has been seeping into low area of the surrounding sand & gravel fill until the drain plumbing is finalized and the concrete floor area is re-poured.
I keep dipping out the water, only for more water under the basement floor to seep back into the hole.
So the question is, is it common for basement floors to have water under them even when the exterior perimeter drain seems to be functioning correctly? Again, I’ll he basement walls & floor are otherwise dry and no seepage or floor condensation is otherwise observed.
Great question, Randy! It actually is common for most basement floors to have water underneath them. After all, what’s underneath your floor but the Earth? And when it rains, water is present.
A Drain Tile System is designed to keep water beneath the floor level, but it does not eliminate all water underneath your home. Again, that dirt/water goes all the way to the center of the Earth! The main purpose is to keep the water level low enough that it does not come through the floor or Cove Joint.
If the only water you are seeing is underneath the floor where you opened up the slab to re-do the plumbing, I would not worry about that. If that water rises to the point where it comes through the floor, that is when you know you need to install a new Drain Tile System. The existing Clay Drain Tiles that were installed at the time of construction will collapse and clog over time. Just something to keep an eye on.
Let me know if you have any other questions!
Can you recommend someone in Almena Wisconsin? Friend’s basement is under 1″ of water and it’s still coming in
Unfortunately, we don’t know anyone up in Almena. Best bet is to compare reviews across all sites (Yelp, Angie’s, BBB, Google) to see who is consistently making their customers happy.
I have an older home in Norridge Il, 30 years ago I dug the basement floor down a foot due to a low ceiling, I found there was no footing under the concrete foundation so we formed out an interior footing at the bottom to secure the foundation , my Plumber installed Pex tube heating in the floor before the full pour, I asked him if we need to add drains or Drain Tile & he said no it will never leak, so 30 years later I still get water after heavy rains in certain places. I’m sure I need Drain Tile but in order to cut the floor I’d probably cut the Pex Heat Tubing since it goes up to the Foundation walls, the tubing could be repaired but that’s a ton of connections to splice together, Now that I rattled you a bit, what are your thoughts ?
That’s definitely an interesting one. You will need a Drain Tile to keep water from flooding your basement. In order to do so, you are correct, we will need to cut open the floor and break some of those tubes. How this works whenever we run into radiant floor heating is the plumber will need to come turn off the system before we start, repair the tubes once we have dug out the trench, and then start/test the system to make sure it’s back to functionality.
The only way to avoid this is to dig the foundation out from the outside to install the Drain Tile System. This tends to be much more expensive, and the preferred method is still from the interior.
Thank You for getting back so quick, I’d like for you to look at what I have & the best way to repair , it will be from the interior for sure. Please E-Mail me all you contact info Have a Great Easter !!
We’ll send you an email, hope you had a great Easter!

I have water coming from the cement basement floor. The concrete floor is very old and the water is coming up from the center as well as from the cove joint near one of the walls.
My question is:
Can placing a sump pit and pump near that cove joint (which is also the lowest part of the floor) prevent the water from coming up in the center of the room.
Should I dig into the center and place a perforated pipe running to the wall where the pit is or will the pump by the wall be enough to absorb the water underneath.
We have some great videos of this on our media page. To be clear, a sump pit and pump in the corner will not solve your water issue. In order to capture the water in the middle of the floor, you will need to run 4″ Drain Tiles along the perimeter of the basement that lead to that sump pit. It is a large project to be sure.
How water gets in through the floor is pretty simple. You have a “bowl” in the ground where your house sits that will fill up with water in rain. As the water builds up, it surrounds the house and builds pressure. This pressure will start to push water through the concrete floor via cracks, low spots, and the cove joint. Installing the perimeter Drain Tiles that I mentioned above will keep the water from building up enough to push through the floor.
I would not suggest doing one line of Drain Tile to the center of the floor. If you plan on living in your house forever and this works, great. If you ever plan on selling, anyone coming in will, rightfully so, point out that it wasn’t done correctly. They’ll then ask for credits to install a proper Drain Tile with a warranty.
