Foundation Repair questions, answered by experts

It’s usually not an immediate safety risk to live in a house with foundation problems, but you don’t want to let those problems persist. Most foundation issues don’t lead to a house’s sudden collapse, but they can lead to health issues like mold growth and pest intrusion, as well as problems like uneven floors or rotten beams and joists, which can pose injury risks and be costly to fix.

Some foundation repairs are permanent, like underpinning and exterior drainage systems like the French drain. These fixes address the underlying problems—insufficient support from the soil and hydrostatic pressure on your foundation walls, respectively—so they can last for many decades, making them “lifetime fixes.” There are other solutions to address these issues that will last for up to a decade, making them temporary. These include slabjacking to raise concrete slabs back into place and dampproofing to reduce the water in the soil that interacts with the concrete foundation.

Many horizontal cracks in home foundations result from water and soil pressure from outside of the building or from a footing that is shifting. Under those circumstances, horizontal cracks are a structural problem that requires repair before they become worse and more difficult to fix. However, in very specific cases, thin horizontal cracks may simply be a cosmetic blemish due to concrete shrinkage.

You can patch minor cracks and damage yourself using concrete fillers or mortar. Larger damage may require full replacement of affected slabs. However, water damage to your concrete will never disappear unless you address the root cause causing the water to cumulate. To prevent future damage, you can also waterproof your concrete.

Yes, all basement floors crack in response to the natural settlement of the soil around them and from concrete shrinkage as it cures, and you’ll see hairline cracks as a result. However, you should keep an eye on your basement floor to see if cracks continue to lengthen or widen or show signs of water intrusion. In any of these cases, the problem is likely not settling or shrinkage, and a professional repair is necessary.
