Foundation Repair FAQs, answered by experts

Foundation cracks that are 1/8 inch wide or less, aren’t uneven across the gap, and don’t continue widening over time are usually just normal settling cracks and don’t suggest structural issues. Horizontal cracks and stair-step cracks on foundation walls, any cracks that continue widening, are wider than 1/8 inch, or where one side juts out beyond the other, are often indicative of structural damage.

While it can be difficult to identify a bad foundation at first glance, look for large horizontal cracks, discoloration, bulging basement walls, or signs of water damage. You may also see large gaps between the home and the foundation on the outside or signs of pooling water from a recent storm.

The best foundation repair method will depend on the issue you’re having, but usually, foundation instability is best fixed using supportive piers, like steel piers or helical piers. A professional foundation repair contractor or structural engineer should always decide what the best course of action is, and even then, it’s imperative that you also take measures to treat the underlying issue as well, like soil erosion or oversaturation from runoff.

Yes, slab foundations can sink just like any other foundation type. Floating slabs are the most prone to differential settlement and foundation sinking because they sit directly on the surface of the earth. Slab foundations that have footings—including slab-on-grade foundations and monolithic slab foundations—get additional support from soil further down and are less likely to sink over time, especially under larger, heavier structures.

If your concrete steps have crumbled or chipped, you can fix them by removing any chips or flakes, cleaning and wetting the affected area, applying a concrete bonding agent, and finally applying new concrete, usually in the form of Portland cement. For widespread damage, you can consider concrete resurfacing instead. For fixing concrete spalling that has led to deep damage, you might need to remove damaged material, add structural supports, and pour new concrete into a mold.
