Is a sinking concrete slab diminishing the appeal and safety of your property? Whether it’s your driveway, patio, walkways, basement floors and more, experiencing this common issue, there’s a reliable and efficient solution to consider. In this guide, we’ll walk you through the concrete lifting process, a proven method for fixing sinking concrete slabs without the need for complete replacement.
Why Does Concrete Sink?
Sinking concrete slabs occur due to various reasons, such as soil erosion, poor compaction, and natural settling over time. Not only can this cause tripping hazards and water drainage issues, but it also affects the aesthetic and value of your property. Fortunately, with advancements in repair techniques, there’s no need to endure the disruption and expense of tearing out and replacing your concrete.
Settled Concrete Slab Repair
Concrete lifting, particularly using polyurethane foam, offers a cutting-edge solution to this problem. Here’s a closer look at how this process can fix your sinking concrete slab efficiently:
- Preparation and Access: On the scheduled day, the team arrives with specialized equipment housed in a trailer. Thanks to the flexible hose, which can extend to almost any length, the equipment can stay parked while the crew accesses the repair site.
- Strategic Drilling: The first step involves drilling injection holes into the concrete slab. These holes are strategically placed to ensure the entire area needing repair is effectively covered.
- Injection of Polyurethane Foam: A two-part liquid polyurethane foam, specifically engineered for concrete lifting, is then injected beneath the slab. This foam is designed to infiltrate air spaces, filling voids and raising the concrete slab to its correct level.
- Controlled Expansion: The foam has an average reaction time of just 12 seconds, expanding in a controlled manner to avoid any damage to the concrete. It reaches approximately a 3 to 6-foot diameter beneath the slab, ensuring thorough coverage and lifting.
- Precision Lifting: Our skilled technicians employ a “bunny hop” technique, moving from hole to hole to gradually and carefully lift the slab. This method minimizes the risk of breaking the concrete, a testament to the expertise and precision of our team.
- Final Touches: After the lifting process is complete, the injection holes are filled and the site is cleaned up, leaving your concrete slab looking as good as new.
Why Choose Polyurethane Foam Lifting?
Choosing this method for fixing your sinking concrete slab comes with numerous benefits:
- Minimally Invasive: Unlike traditional methods, this process causes minimal disruption to your property and daily routine.
- Cost-Effective: It’s significantly more affordable than concrete replacement, offering a budget-friendly alternative without compromising quality.
- Long-Lasting: Polyurethane foam provides a durable solution, with the lifted concrete remaining stable and level for years.
- Quick and Efficient: The entire lifting process can be completed quickly, allowing you to use the repaired area soon after the job is done.
Conclusion
Fixing a sinking concrete slab doesn’t have to be a daunting or expensive endeavour. With the concrete lifting process, specifically utilizing polyurethane foam, you can achieve a lasting solution that restores safety, functionality, and aesthetics to your property. Our experienced technicians, equipped with specialized knowledge and equipment, ensure that your concrete lifting project is executed flawlessly, providing peace of mind and significant savings over traditional replacement methods. If your property is facing this common issue, consider the efficient and effective option of concrete lifting.
