How Polyurethane Foam Injection Works
Polyurethane foam injection, also known as polyjacking or foam jacking, is a modern and minimally invasive method used to lift sunken concrete slabs, fill voids, and stabilize soil beneath foundations. In Union City, TN, where soil movement and moisture fluctuations are common, this technique is particularly useful for quickly restoring sunken driveways, sidewalks, patios, garage floors, and interior slabs.
At Union City Foundation Repair, we use high-density polyurethane foam to correct uneven surfaces with minimal disruption. The foam is injected through small holes drilled into the affected slab. Once injected, the foam expands beneath the concrete, filling voids and gently lifting the slab back to its original level. The foam cures rapidly, typically within 15 minutes, allowing for immediate use of the area.
Our Polyurethane Foam Injection Process:
- Identify the cause of the slab settlement (soil compaction, erosion, water damage)
- Drill small, strategically placed holes (usually 5/8″) in the sunken slab
- Insert injection ports into the holes
- Inject expanding polyurethane foam under the slab
- Monitor the lift in real time using precision leveling tools
- Fill holes and clean up the site once the desired elevation is achieved
Unlike traditional mudjacking, polyurethane foam is lightweight, hydrophobic (water-resistant), and long-lasting—making it the preferred choice for many modern concrete leveling applications.

Benefits of Polyurethane Foam Injection
Polyurethane foam injection offers fast, efficient, and long-lasting results without the mess or disruption of more invasive foundation repair methods.
Key Benefits:
- Fast Cure Time
Most slabs are ready for use within 30 minutes of repair—ideal for driveways, garages, and commercial settings. - Minimal Disruption
Small injection holes and no heavy equipment minimize damage to landscaping and structures. - Accurate Leveling
Foam expands with controlled force, allowing precise lifting of slabs and surfaces. - Long-Term Durability
The foam resists water, will not shrink, and remains stable in shifting soil conditions. - Lightweight Material
Unlike heavy concrete slurry used in mudjacking, foam doesn’t add weight that could worsen settlement issues. - Fills Voids & Stabilizes Soil
The foam fills underground gaps caused by erosion, pests, or improper compaction. - Cost-Effective Alternative to Replacement
Foam injection can be 50–75% less expensive than tearing out and replacing concrete slabs.
This solution is perfect for homeowners, business owners, and municipalities looking for a clean, effective, and quick way to correct concrete settling.
What to Expect During Polyurethane Foam Injection
Union City Foundation Repair follows a proven, step-by-step process to ensure that every polyurethane foam injection project is safe, successful, and built to last.
Our Foam Injection Process:
- Inspection and Elevation Mapping
We evaluate the extent of the slab movement, map current elevations, and identify voids using laser levels and ground-penetrating tools. - Drilling Access Points
Small holes are drilled through the slab at key lift points. These holes are kept as small and clean as possible. - Foam Injection
High-density foam is injected through ports. As it expands, the slab is gently raised while filling any empty space underneath. - Monitoring the Lift
Our crew carefully monitors the lift, making small adjustments to avoid cracking or over-lifting. - Sealing and Clean-Up
Once the slab is level, we seal the injection holes with non-shrink grout and clean the site. The area is often usable immediately. - Post-Repair Evaluation
We recheck elevations and ensure the surface is safe and level.
This entire process typically takes a few hours for most residential projects, making it one of the fastest structural correction options available today.
