Over time, concrete surfaces can become uneven, cracked, or sunken due to various factors such as soil erosion, water intrusion, and heavy loads. Traditional concrete leveling methods like mudjacking or complete replacement have long been the go-to solutions. However, a modern, more efficient alternative is now the standard: polyurethane foam injection (a.k.a. PolyJacking). This innovative technique offers numerous benefits, including cost-effectiveness, quick installation, and minimal disruption to daily activities.

In this post, we will delve into the advantages of polyurethane foam injection for concrete repair and explore why it is becoming the preferred choice for many experts in the industry.

What is PolyJacking?

Polyurethane foam injection, also known as polyjacking, involves injecting a two-part polyurethane mixture beneath the affected concrete surface. The mixture expands and hardens, filling voids and lifting the concrete to its original level. This method is highly effective for repairing sidewalks, driveways, pool decks, garage floors, and even industrial floors.

Why Choose Polyurethane Foam Injection?

1. Cost-Effectiveness

One of the most compelling benefits of polyurethane foam injection is its cost-effectiveness. Traditional concrete repair methods, such as complete replacement, can be expensive and labor-intensive.

Polyurethane foam injection, on the other hand, requires less material and labor, significantly reducing overall repair costs. In some cases, polyjacking can be up to 50% cheaper than traditional concrete replacement.

2. Quick Installation

Time is money, especially in the construction industry. Polyurethane foam injection offers a rapid solution to concrete repair that minimizes downtime. The foam sets and cures within minutes, allowing the repaired area to be ready for use almost immediately.

This is particularly beneficial for businesses and homeowners who need to maintain regular operations without extended interruptions. Most polyjacking projects can be completed in just a few hours.

3. Minimal Disruption

Traditional concrete repair methods often involve heavy machinery, extensive excavation, and noisy operations, which significantly disrupt daily activities. Polyurethane foam injection, however, is a minimally invasive technique.

The equipment used is compact and the process generates minimal noise and mess. This makes it an ideal solution for residential areas, commercial properties, and sensitive environments where disruption must be kept to a minimum.

4. Durability and Longevity

Polyurethane foam is a durable and long-lasting material. Once injected, it forms a strong, stable base that can support heavy loads and resist environmental factors such as moisture and temperature changes. Polyjacking repairs can last for many years, making it a reliable investment for property owners.

5. Lightweight and Environmentally Friendly

Polyurethane foam is significantly lighter than traditional mudjacking materials, which reduces the risk of further soil compression and settlement. Additionally, the foam is environmentally friendly, as it does not leach harmful chemicals into the ground. This makes polyjacking a sustainable choice for eco-conscious property owners and construction professionals.

6. Versatility

Polyurethane foam injection is a versatile solution that can be used for a wide range of concrete repair applications. Whether it’s lifting a sunken driveway, leveling a pool deck, or stabilizing an industrial floor, polyjacking can handle it all. This method is suitable for both residential and commercial projects, making it a versatile tool in any contractor’s arsenal.

How Do Polyurethane Foam Injections Work?

The process of polyurethane foam injection is straightforward and efficient:

  1. Assessment: The affected area is thoroughly inspected to determine the extent of the damage and the appropriate injection points.
  2. Drilling: Small holes (usually 5/8-inch in diameter) are drilled into the concrete at strategic locations.
  3. Injection: The polyurethane foam is injected through the holes using specialized equipment. As the foam expands, it fills voids and lifts the concrete back to its original level.
  4. Sealing: The injection holes are sealed with a high-quality patching material, leaving the surface smooth and even.

The Future of Concrete Repair

Polyurethane foam injection is transforming concrete repair with its cost-effectiveness, quick installation, minimal disruption, durability, eco-friendliness, and versatility. As demand for sustainable solutions grows, polyjacking is set to become the industry standard.
