How Polyurethane Foam Injection Works
Polyurethane foam injection is a cutting-edge technique used to lift and level sunken concrete slabs. It’s an efficient, long-lasting, and non-invasive alternative to traditional methods like mudjacking. This advanced solution is ideal for repairing driveways, sidewalks, patios, garage floors, and foundation slabs.
Step 1: Inspection and Evaluation
Before starting the repair, we conduct a detailed assessment of the affected concrete slab:
- Identifying Areas of Settlement: Check for uneven surfaces, trip hazards, or depressions.
- Assessing the Soil Condition: Evaluate whether soil compaction or erosion has contributed to the issue.
- Determining the Best Injection Points: Strategically mark areas where the polyurethane foam will be injected.
Step 2: Polyurethane Foam Injection Process
We use high-quality, expanding polyurethane foam to lift and stabilize the sunken slab:
- Drill Small Injection Holes: We drill tiny holes (smaller than a dime) in the affected slab to insert the injection ports.
- Inject the Expanding Foam: A two-part polyurethane foam is injected beneath the slab. As it expands, it fills voids and lifts the concrete.
- Monitor and Adjust: We carefully monitor the lift, ensuring even restoration of the slab.
- Sealing and Cleanup: Once the slab is leveled, the injection holes are sealed, leaving the area clean and fully restored.
Step 3: Post-Repair Inspection and Preventative Measures
- Confirm that the slab is stable and properly leveled.
- Provide maintenance recommendations to ensure longevity.

Choosing Polyurethane Foam Injection for concrete lifting offers several advantages over traditional methods:
Fast and Non-Invasive
- Requires minimal downtime; most projects are completed in a few hours.
- No heavy excavation or mess left behind.
Durable and Long-Lasting
- The polyurethane foam remains stable and does not break down over time.
- Prevents future sinking by stabilizing the soil beneath the slab.
Cost-Effective Alternative to Replacement
- Restores concrete surfaces at a fraction of the cost of replacement.
- Extends the lifespan of existing slabs without expensive new installations.
Eco-Friendly and Lightweight
- The materials used are environmentally safe and non-toxic.
- Unlike mudjacking, the lightweight foam does not add extra weight to the soil, reducing the risk of future sinking.
