Seattle - Foam Jacking

Get help with your foam jacking needs. Fill out the form above and we will connect you with local pros in your area. Foam jacking, also known as polyurethane foam injection or slab lifting, is a highly effective method used to repair and stabilize sunken or uneven concrete surfaces. This technique involves injecting a specialized foam material into the affected area, which expands and hardens to lift and level the concrete. One of the key benefits of foam jacking is its cost-effectiveness compared to traditional methods like concrete replacement. It is also a quicker and less disruptive process, as it requires minimal excavation and can be completed in a matter of hours. Foam jacking provides long-lasting results, as the foam material is resistant to erosion and can support heavy loads. Additionally, it is an environmentally friendly solution, as the foam material is non-toxic and does not release harmful chemicals into the soil or groundwater. Overall, foam jacking offers a durable, efficient, and eco-friendly solution for addressing sunken or uneven concrete surfaces.


Foam jacking, also known as polyurethane foam injection, is a cost-effective and efficient method used for concrete leveling and foundation repair. This innovative technique involves injecting expanding foam into the voids beneath settled or sunken concrete slabs, effectively raising and stabilizing them. By utilizing high-density polyurethane foam, foam jacking offers a long-lasting solution for uneven or sinking concrete surfaces, such as sidewalks, driveways, and patios. This process not only restores the structural integrity of the affected area but also helps prevent further damage. Foam jacking is a popular choice among homeowners and business owners looking for a reliable and sustainable solution to their concrete settling issues.

Q: How Does Foam Jacking Work And What Are Its Benefits?

Answer: Foam jacking, also known as polyurethane foam injection, is a process used to lift and level sunken concrete slabs. It involves injecting a specialized foam material beneath the slab, which expands and raises it back to its original position. The foam hardens quickly, providing a stable and durable foundation. The benefits of foam jacking include cost-effectiveness, minimal disruption to the surrounding area, long-lasting results, and improved aesthetics.

Q: What Are The Typical Applications Or Situations Where Foam Jacking Is Used?

Answer: Foam jacking is typically used in situations where there is sunken or uneven concrete, such as sidewalks, driveways, and foundations. It is also commonly used for repairing and leveling concrete slabs in commercial and residential buildings.

Q: Are There Any Limitations Or Potential Risks Associated With Foam Jacking?

Answer: Yes, there are limitations and potential risks associated with foam jacking. Some limitations include the inability to lift heavy structures, limited effectiveness on unstable or shifting soils, and the potential for foam to expand too much and cause damage. Risks may include the possibility of foam leakage, improper foam mixing leading to weak or ineffective lifts, and the need for careful planning and execution to avoid unintended consequences.
