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>

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>

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

• <div><p>If you don&rsquo;t have any access to or knowledge of any area underneath your home, chances are it&rsquo;s built slab-on-grade. You can also look for the concrete around the bottom edge of your structure; if it&rsquo;s just a few inches tall, it&rsquo;s likely a slab.

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 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: What services do cement companies offer?

• <div><p>Cement companies offer a wide variety of services, including delivering and <a href="https://www.angi.com/articles/how-do-contractors-pour-solid-concrete-foundations.htm">pouring concrete for home foundations</a>, walkways, patios, driveways, concrete steps, pools, pool decks, and more, plus concrete repair and patching. Most companies also have the ability to demolish and haul away old concrete landscaping features. It&rsquo;s a good idea to reach out to a few different companies before hiring to make sure you choose one that can tackle the entirety of the project you have from start to finish. This method will typically save you some money over hiring multiple contractors. </p></div>

What really sold me on this shop was the courtesy I was given by the employee's. I did not talk to the repair man until the next day. What blew me away that they did not charge for the service. I will take the machine back if I have any problems. I will also delight in shopping at this store.
