When concrete repair or leveling is a must for your home polyjacking is one of the more popular options. It’s known for offering a rapid, efficient, and minimally invasive solution compared to traditional concrete leveling methods such as mudjacking. It not only corrects uneven surfaces but also addresses underlying issues without disrupting too much.
Now that you know the basics, let get into the details.
What is Polyjacking?
The Polyjacking Process
Polyjacking is a sophisticated concrete leveling technique that involves injecting polyurethane foam into the ground beneath a sunken concrete slab. Here’s a more detailed breakdown of the process:
– Drilling: The process starts when small holes are drilled into the concrete slab at strategic locations.
– Injection: Then, a two-part polyurethane foam is then injected into these holes. The foam components mix and begin to expand upon injection.
– Lifting: As the foam expands, it fills voids and gaps beneath the slab, exerting upward pressure that lifts the concrete back to its original level.
– Stabilization: The hardened foam then stabilizes the concrete slab, preventing future settlement and a quick, durable solution.
How Polyurethane Foam is Used to Lift and Stabilize Concrete
Polyurethane foam is central to the polyjacking process thanks to its unique properties:
– Lightweight: Unlike traditional mud slurry used in mudjacking, polyurethane foam is incredibly lightweight, which helps prevent further soil compression beneath the slab.
– Durable: The foam is highly durable and resistant to water and other environmental factors, ensuring a long-lasting repair.
– Efficient: The quick expansion and curing time of the foam make polyjacking a fast repair method, often completed within hours.
Polyjacking not only lifts the concrete but also provides a long-term solution to underlying issues by stabilizing the area with a strong, supportive base of hardened polyurethane foam. This method of foam lifting is increasingly preferred for various concrete repair needs due to its efficiency and effectiveness in handling both residential and commercial projects.
The Benefits of Polyjacking Over Mudjacking
When it comes to the debate of ployjacking vs. mudjacking, polyjacking tends to offer several advantages over traditional mudjacking. This includes environmental benefits, efficiency, and just overall long-term effectiveness, making it a superior choice for concrete leveling in various aspects,
Environmental Benefits
Polyjacking is considered a more sustainable concrete solution due to several key environmental benefits:
– Eco-Friendly Materials: The polyurethane foam used in polyjacking is often made from recycled materials and is recyclable, contributing to a reduced environmental footprint.
– Less Invasive: The process requires smaller and fewer holes in the concrete, which means less material is disturbed during repair, reducing the ecological impact on the surrounding area.
– Water Resistance: Unlike mudjacking, polyurethane foam is hydrophobic, meaning it does not absorb water and will not introduce additional moisture into the soil, preserving the local ecosystem’s balance.
Efficiency
Polyjacking’s efficiency is unmatched when compared to mudjacking:
– Faster Application: The foam cures and hardens quickly, allowing the repair to be completed in hours instead of days.
– Immediate Use: Concrete slabs are often ready to bear weight within 15 minutes to an hour after foam injection, minimizing downtime for homeowners and businesses.
Long-Term Effectiveness
The long-term effectiveness of polyjacking is evident through various factors:
– Durability: Polyurethane foam is resistant to material breakdown from chemicals and water, ensuring the longevity of the repair and your concrete.
– Stability: The foam offers a more stable lift and leveling by filling voids effectively and maintaining its volume over time. This prevents further settlement.
– Reduced Need for Future Repairs: Due to its durability and stability, polyjacking reduces the likelihood of needing future repairs, providing a cost-effective long-term solution.
How Polyjacking Works
Polyjacking is a precise and technical process that involves several steps to ensure effective and long-lasting concrete leveling.
Step-by-Step Breakdown of the Polyjacking Process
1. Initial Assessment
Before any work begins, a professional contractor conducts a thorough assessment of the affected concrete area. This includes identifying the cause of sinking or damage, evaluating the extent of the issue, and planning the injection points.
2. Preparation
The surface is prepared by cleaning and drilling small holes at strategic locations across the concrete slab. These holes are typically about the size of a dime, minimizing visual impact.
3. Foam Injection
A two-component polyurethane foam is injected through the holes into the sub-surface. This foam quickly reacts and expands, filling any voids and gaps beneath the slab.
4. Lifting and Leveling
As the foam expands, it exerts upward pressure, lifting the concrete slab back to its original level. The technician carefully monitors the lift to ensure precision and prevent over-lifting.
5. Curing and Sealing
The foam cures rapidly, often within minutes. Once curing is complete, the injection holes are sealed, and the surface is cleaned to finish the process.
Importance of Professional Assessment and Precise Foam Injection
The effectiveness of polyjacking heavily relies on the accuracy of the initial assessment and the precision of the foam injection:
Expertise in Evaluation
Professional contractors are skilled in diagnosing the underlying causes of concrete issues. Their expertise ensures that the repair addresses both the symptoms and the root causes, preventing future problems.
Precision in Foam Injection
The exact amount of foam, its injection pressure, and the placement of injection points are critical. Precision in these areas ensures that the lift is even, stable, and does not cause additional stress or damage to the slab.
