Common Concerns About Concrete Lifting

Concrete lifting is a common solution for addressing issues like uneven, cracked, or sunken concrete slabs. However, homeowners often have several concerns regarding the process. Here are some of the key points to consider:

Types of Concrete Lifting

1. Polyurethane Foam Injection:

• Pros: This method involves injecting a lightweight foam that expands to lift the concrete. It requires smaller drill holes, is minimally disruptive, and provides long-lasting results.
• Cons: It tends to be more expensive than other methods due to the cost of materials​ (Concrete Pro Care)​ (Foundation Recovery Systems).

1. Mudjacking:

• Pros: Uses a slurry of cement, sand, and water to lift the concrete. It's effective for many situations and is generally less expensive than polyurethane foam.
• Cons: Larger drill holes are needed, and it might not be suitable for heavy structures or extensive lifting​ (Foundation Recovery Systems)​ (Alpha Foundations).

1. Stone Slurry Grout:

• Pros: Combines aspects of mudjacking and foam injection using a mixture of crushed stones and water, providing a durable solution.
• Cons: More expensive than mudjacking and requires a larger drill hole compared to polyurethane foam​ (Concrete Pro Care).

Common Concerns

1. Effectiveness and Durability: Homeowners worry about how long the repair will last. Polyurethane foam is known for its durability and long-term effectiveness, while mudjacking might settle over time if the underlying soil is not stable​ (Concrete Pro Care)​ (Foundation Recovery Systems).
2. Cost: The cost varies based on the method used, the extent of the damage, and the size of the area. Polyurethane foam is typically the most expensive, followed by stone slurry grout and mudjacking. The cost can range from a few hundred to several thousand dollars depending on the project specifics​ (Concrete Pro Care)​ (Foundation Recovery Systems).
3. Safety and Liability: Uneven concrete can be a tripping hazard and reduce property value. Addressing these issues promptly can prevent accidents and potential liability​ (Alpha Foundations).
4. When to Seek Professional Help: While minor cracks might only need cosmetic repairs, significant settling or lifting usually requires professional intervention to ensure the job is done correctly and safely​ (Foundation Recovery Systems)​ (Alpha Foundations).

By understanding these aspects, homeowners can make informed decisions about which concrete lifting method suits their needs and budget. Consulting with local experts and getting a detailed inspection can provide a tailored solution for specific issues.
