Introduction
When it comes to concrete structures, cracks and uneven surfaces are all too common. They not only pose safety risks but also diminish the aesthetic appeal of buildings and infrastructure. Fortunately, a groundbreaking technique called polyjacking offers a powerful solution to combat these issues. By leveraging a unique blend of materials and precise engineering, polyjacking provides a game-changing approach to concrete repair. In this comprehensive guide, we will delve into the world of polyjacking, exploring its benefits, applications, and how it can transform your cracked surfaces into masterpieces of strength and durability.
What is Polyjacking?
Understanding the concept
Polyjacking, also known as polyurethane concrete raising, is a cutting-edge method used to lift, level, and stabilize concrete slabs. It involves injecting a high-density polyurethane foam into the affected area, which expands and hardens, effectively filling voids and raising the sunken concrete. This innovative technique provides a cost-effective and efficient alternative to traditional repair methods.
How it works
The polyjacking process begins with a thorough assessment of the damaged concrete surface. Once the extent of the problem is determined, small holes are strategically drilled into the concrete. Through these access points, the polyurethane foam is injected, utilizing specialized equipment and techniques. As the foam expands, it fills voids, lifts the concrete, and restores it to its original position. The hardened foam acts as a stable foundation, ensuring long-lasting results.
The Science Behind Polyjacking
Exploring the materials involved
Polyjacking relies on a unique combination of materials, with polyurethane foam being the key ingredient. This foam is specially formulated to have high density and expansive properties, allowing it to effectively lift and level concrete surfaces. The foam is composed of two components, which, when mixed, create a chemical reaction resulting in expansion and hardening.
The chemical reaction process
When the two components of the polyurethane foam mix, they undergo a rapid exothermic reaction. This reaction creates expanding foam, which fills voids and raises the sunken concrete. The foam hardens within minutes, providing immediate structural support. The chemical reaction is carefully calibrated to ensure precise control over the foam’s expansion and curing time.
Common Applications of Polyjacking
Polyjacking offers a versatile solution for various types of concrete structures. Whether it’s residential buildings, commercial properties, or large-scale infrastructure projects, polyjacking can be employed to address a wide range of issues. Some common applications include:
- Driveways and sidewalks
- Patios and pool decks
- Foundations and basement floors
- Parking lots and garages
- Warehouse and industrial floors
Advantages of Polyjacking
Polyjacking provides several significant advantages over traditional concrete repair methods. Let’s explore these benefits in detail:
Cost-effectiveness
Polyjacking is often more cost-effective than completely replacing the concrete structure. By repairing the existing foundation instead of starting from scratch, you can save a substantial amount of money. Additionally, polyjacking reduces the need for extensive labor, minimizing both time and expenses.
Enhanced structural integrity
Polyjacking not only fixes cosmetic issues but also restores the structural integrity of concrete. By lifting and stabilizing sunken slabs, polyjacking eliminates trip hazards, prevents further damage, and ensures the longevity of the repaired surfaces.
Time efficiency
Unlike traditional methods that may require days or even weeks to complete, polyjacking offers remarkable time efficiency. Most polyjacking projects can be finished within a day, allowing you to swiftly regain access to your repaired areas and minimize disruptions.

The Polyjacking Process Explained
To better understand how polyjacking works, let’s break down the step-by-step procedure:
- Assessment: A thorough inspection of the damaged area is conducted to determine the feasibility and extent of repair required.
- Drilling: Small holes are carefully drilled into the affected concrete surface to create access points for the polyurethane foam.
- Injection: The polyurethane foam is injected into the holes under controlled pressure, allowing it to expand and fill voids.
- Lift and Level: As the foam expands, it lifts the sunken concrete, leveling it with precision.
- Patching: After the foam has hardened, the access holes are patched and the repaired area is cleaned, leaving behind a seamless surface.
Factors to Consider Before Polyjacking
Before opting for polyjacking, there are certain factors that should be taken into account:
Assessing feasibility
Polyjacking is suitable for most minor to moderate concrete damages. However, severe structural issues may require alternative repair methods. Consulting with professionals and conducting a thorough assessment is crucial to determine the suitability of polyjacking for your specific situation.
Determining the extent of damage
Understanding the severity of the damage is essential for effective repair planning. Identifying whether the issue is localized or widespread helps in determining the number of injection points required and the amount of polyurethane foam needed.
Consulting professionals
Polyjacking is a specialized technique that requires expertise and experience. It is advisable to consult professionals who are well-versed in polyjacking to ensure a successful repair process. Professional contractors will have the necessary knowledge and equipment to handle the job efficiently.
Safety Precautions During Polyjacking
While polyjacking is generally a safe and non-invasive procedure, it is important to prioritize safety. Here are some essential safety precautions to follow:
- Wear protective gear, including goggles, gloves, and appropriate clothing, to avoid contact with chemicals and prevent injuries.
- Ensure proper ventilation in enclosed areas to dissipate any fumes emitted during the polyjacking process.
- Follow the manufacturer’s instructions regarding the handling and disposal of polyurethane foam and other materials used in the process.
- Keep bystanders and pets away from the work area to avoid any accidents or unnecessary exposure.
