Water leaking through a crack in the floor slab is a common way for water to enter a basement or crawlspace. There are many possible causes for this kind of leak—most commonly, after a day of rain, water pressure on the outside of your foundation (either next to it or below it) can build up. Water wants to find the path of least resistance, and sometimes that path is into your home through a crack in the floor slab. Many times, this crack is actually a joint of two pieces of concrete that have dried at different rates/times—this is called a cold joint. While cold joints are standard in the building process, water could also be coming in through a different kind of crack in the concrete.
Whether if the water is coming through a cold joint or an actual crack in the floor, the water pressure could be building on the outside for a variety of reasons. There could be a high water table or a perched water table, or there could be water flow ramifications from excavating virgin soil for the home’s basement or crawlspace. This last possibility is called the clay bowl effect. There could also be grading problems in the surface above: either the yard, or changes to the driveway or patio allowing water to flow towards the home instead of away from the home. There are also other possible causes for water leaking into your basement or crawlspace to consider.
However, it can be very difficult to determine the exact cause(s) of water leaking through a crack in the floor—and there’s always a chance of other causes developing in the future.
