Poly jacking, also known as polyurethane foam jacking, is a method for lifting and leveling sunken concrete slabs by injecting high-density polyurethane foam beneath them. This foam expands, raising the concrete to its original position with precision.

Poly jacking is considered more advanced than mudjacking due to its use of lightweight polyurethane foam, which is less invasive and does not add extra weight to the underlying soil. Additionally, it requires smaller injection holes, causes minimal disruption, and the cured foam is more resistant to water and erosion, offering a longer-lasting solution.

Yes, the polyurethane foam used in poly jacking is environmentally friendly. It is made from partially recycled materials and does not contain harmful chemicals that can leach into the ground. Moreover, its durability means less frequent repairs, contributing to less waste over time.

Yes, one of the advantages of poly jacking is that it can be performed in colder temperatures compared to traditional concrete repair methods. The chemical reaction that causes the foam to expand and harden is not significantly affected by cold weather.

The duration of the poly jacking process can vary depending on the size and complexity of the job. However, most residential projects can be completed in just a few hours, and the area can be used almost immediately after the procedure is finished.

The cost of poly jacking varies depending on factors such as the size of the area, the extent of the sinking, and geographical location. However, it is generally more cost-effective than complete concrete replacement and competitive with mudjacking, while offering superior, long-term results.

While poly jacking is suitable for a wide range of applications, there are instances where severely damaged concrete may need to be replaced. A professional evaluation can determine if poly jacking is the right solution for a specific situation.

When performed correctly, the results of poly jacking can last for many years, often as long as the concrete slab itself. The longevity of the repair depends on various factors, including the condition of the soil underneath and proper maintenance. The polyurethane foam is highly durable and resistant to water, helping to prevent future settling and cracking.
