How do you test for foundation problems?

• <div><p>You can use a level or straight-edge to test for plumb foundation walls and a level slab, a level or a ball to check for sloping floors inside your home, and a hygrometer to look for moisture in your underhome area. Aside from these DIY tests, it’s important to get a foundation repair specialist or structural engineer to test the foundation to see if it’s supporting your structure properly. They can determine if the loads on the concrete are uneven or need reinforcement.</p></div>

Are foundation repairs permanent?

• <div><p>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. </p></div>

Q: How can you tell if a concrete job is bad?

• <div><p>Visible cracks, scaling, flaking, and uneven surfaces indicate a bad concrete job. Additional signs vary depending on the project. You may notice poor drainage or even exposed rebar. Quality issues result from using the wrong concrete, rushing the work, or inexperienced workers completing the job.</p></div>

Q: Can tree roots break through concrete?

• <div><p>Tree roots don&rsquo;t necessarily break through concrete on their own, but they can certainly take advantage of existing cracks, even very small ones. As roots grow, they expand the cracks, making them larger and leading to serious and costly foundation damage. It&rsquo;s a good idea to have repairs on any <a href="https://www.angi.com/articles/quarter-inch-crack-my-foundation-major-concern.htm">foundation cracks you&rsquo;re concerned about</a>. </p></div>

Q: Can a slab leak go undetected for a long time?

• <div><p>Depending on the severity, a slab leak can go undetected for months or even years, especially if you don&rsquo;t carry out routine foundation inspections to find foundation leaks early. However, minor leaks are likely to turn into more severe leaks over time, so you might notice increases in water bills and issues with yard drainage, even if the problem is minor.</p></div>
