Concrete slabs can sink for various reasons. Firstly, erosion from poor drainage or leaking pipes can cause issues. Secondly, poorly compacted soil during construction may lead to settling. Lastly, the decay of organic materials under the slab can create voids.
Over time, these issues create gaps or destabilize the soil beneath the concrete. Consequently, slabs settle unevenly.
Polyurethane concrete leveling, also known as slab lifting or slab jacking, offers an effective way to raise and stabilize sunken slabs. The process involves drilling small holes into the slab and injecting expanding polyurethane foam underneath. As the foam expands, it fills voids, compacts the soil, and lifts the slab back into place.
Polyurethane foam has several advantages over other methods like mudjacking. Firstly, it's a minimally invasive process. Secondly, it has a quick curing time, allowing the slab to be usable within 15 minutes. Additionally, it's a lightweight yet durable material. Moreover, it's eco-friendly. Lastly, it's more affordable than total slab replacement in most cases.
A Jack Attack System is sometimes necessary in addition to polyurethane foam. This triangular steel frame helps the technician adjust the slab's position. Often, a measuring device called a dial indicator is used to track the exact level of the slab.
Sunken slabs can affect various areas of your property:
In most cases, polyurethane foam injection works well for residential concrete lifting needs.
If you're dealing with sunken concrete slabs, don't let them diminish your home's safety, value, and appearance any longer. Instead, consult a professional contractor experienced in polyurethane foam lifting to assess your specific situation and determine the best solution for your property. With the right approach, you can enjoy safe, attractive, and level concrete surfaces once again.
