The best way to level a concrete patio is by using a concrete leveling technique known as polyurethane foam injection, or just polyjacking for short. Polyjacking quickly raises and levels an uneven concrete patio surface and provides a long-lasting solution.
Concrete patios can become uneven over time due to various factors like soil settlement, erosion, or freeze-thaw cycles, creating tripping hazards and drainage problems. While there are different methods to address sinking concrete, the referenced technique highlights polyjacking as a highly effective approach.
What is Polyjacking?
Polyjacking is a modern method used to lift and level sunken concrete slabs, such as patios, walkways, driveways, and pool decks. It involves injecting a specialized material beneath the concrete surface to raise it back to its original position.
How Polyjacking Works
The process is relatively straightforward and non-invasive compared to tearing out and replacing the concrete:
- Drill Small Holes: Small, dime-sized holes are strategically drilled through the sunken concrete slab.
- Inject Polyurethane Foam: A high-density polyurethane foam is injected through these holes.
- Foam Expands and Lifts: The foam quickly expands, filling voids beneath the slab and gently lifting the concrete back to the desired level.
- Seal Holes: Once the slab is level, the injection holes are sealed.
Benefits of Using Polyjacking
Based on the referenced information, polyjacking offers significant advantages:
- Quick Process: The injection and leveling are typically completed in just a few hours.
- Quickly Raises and Levels: It effectively lifts the uneven patio surface back into place.
- Long-Lasting Solution: The high-density foam is durable and resistant to moisture, providing a stable foundation that prevents future sinking.
- Minimally Invasive: The small injection holes cause less disruption to your landscaping compared to other methods or full replacement.
- Lightweight Material: The polyurethane foam is much lighter than traditional concrete or mudjacking slurries, putting less stress on the underlying soil.
In summary, using polyurethane foam injection (polyjacking) is presented as a superior and efficient method for leveling a sunken concrete patio, offering both speed and durability.
