Can a slab foundation sink?

• <div><p>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 <a href="https://www.angi.com/articles/slab-on-grade-foundation.htm">slab-on-grade foundations</a> and monolithic slab foundations—get additional support from soil further down and are less likely to sink over time, especially under larger, heavier structures.</p></div>

How do I know if my foundation is slab-on-grade?

• <div><p>If you don’t have any access to or knowledge of any area underneath your home, chances are it’s built slab-on-grade. You can also look for the concrete around the bottom edge of your structure; if it’s just a few inches tall, it’s likely a slab. If it’s more than that, has any windows, or you have steps leading to your main entrance, you likely have a different foundation style.</p></div>

Q: What can I do if my foundation repair claim is denied?

• <div><p>If your foundation repair claim gets denied, the first step is to carefully read over your policy and denial letter so you understand the reason for the denial. Then, gather evidence and documents that can support your case and appeal the denial with your insurance company. If your insurer does not eventually honor your claim, you may want to file a complaint with the insurance department in your state. In some cases, it may make sense to work with an attorney and file a lawsuit.</p></div>

Q: Can a slab leak cause a sinkhole?

• <div><p>It is possible for a slab leak to cause a sinkhole, but it would have to be a particularly serious leak. A slab leak causes the land under your home to erode and if there is enough movement depressions will form in the ground, potentially causing a sinkhole.</p></div>

Q: How can you tell if a crack is structural?

• <div><p>Foundation cracks that are 1/8 inch wide or less, aren&rsquo;t uneven across the gap, and don&rsquo;t continue widening over time are usually just normal settling cracks and don&rsquo;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.</p></div>
