Does expanding foam lift concrete?

• <div><p>Yes, expanding foam (also known as polyurethane foam) can lift concrete. This approach, called polyjacking, involves injecting the foam rather than concrete slurry to fill voids and raise the concrete slab back into place. It’s often faster and requires smaller drill holes than traditional mudjacking, though it may come at a higher cost. Some contractors also prefer <a href="https://www.angi.com/articles/mudjacking-vs-polyjacking.htm">polyjacking over mudjacking</a> for more damaged and delicate slabs.</p></div>

Q: What is the difference between trenching and boring for underground utility installation?

• <div><p>Trenching and boring are two distinct methods for installing underground utilities. Trenching involves digging a channel using equipment like an excavator, trencher, backhoe, or shovel. While it is a simpler process, it causes significant disruption to the surface, landscaping, and surrounding ecosystems.</p><p>Boring, also known as directional boring, is a less invasive alternative that uses a drill to create a tunnel for utility lines without disturbing the surface. This method is more precise and is ideal for installations that need to go underneath buildings, roads, or bodies of water. Although boring is less disruptive, it is generally more expensive than trenching.</p></div>

Q: How much foundation sinking is too much?

• <div><p>Most houses are expected to settle over time, but foundation sinking of more than a few inches or uneven sinking of more than an inch for every 20 feet is cause for concern. Any significant or uneven sinking should be assessed by a professional to determine the cause and perform any necessary repairs. </p></div>

Q: What is a good slump height?

• <div><p>A good slump height really depends on the project, but there is a use for nearly all slump levels. For example, low slumps are best in projects that require structure, such as curbs and roads. High slumps often require additional reinforcement, but they flow more freely into hard-to-reach spaces. </p></div>

Q: What is the cost range for concrete injection leveling?

• <div><p>Charges correlate with surface size, settlement depth, and access, often yielding significant savings over concrete replacement.</p></div>
