The Ultimate Guide to Polyjacking: What You Need to Know


When it comes to foundation repair, there are several methods available to fix settling foundations. One of the most effective and efficient techniques is polyjacking. This comprehensive guide will explore what polyjacking is, how it works, its benefits, and why it is a superior choice compared to other foundation repair methods like mud jacking.

What is Polyjacking?

Polyjacking, or polyurethane foam injection, raises and stabilizes sinking or settling foundations. It involves injecting a polyurethane foam mixture into the affected foundation areas through drill holes, then the expanding polyurethane foam lifts and levels the concrete slab.

Mud jacking concrete, in comparison, tries to achieve the same kind of concrete leveling using mud slurry.

Signs of a Settling Foundation

Before we delve into how polyjacking works, it’s essential to understand the signs that indicate your foundation may be settling. These signs include concrete cracks in the walls or floors, doors or windows that stick or are difficult to open and close, sloping or uneven floors, and gaps between the walls and the floor or ceiling.

There are clear signs of need for concrete repair, as sunken concrete is relatively easy to notice.

How Polyjacking Works

Polyjacking involves a simple yet highly effective process. First, small holes are drilled into the concrete slab. Then, a two-part polyurethane foam mixture is injected into the holes. The foam mixture expands and fills any voids or gaps beneath the slab, providing a solid support base. As the foam expands, it lifts and levels the concrete slab, restoring the foundation to its original position.

Benefits of Polyjacking

Polyjacking offers several benefits over traditional foundation repair methods. Firstly, it is a cost-effective solution that requires minimal disruption to your home or property. Unlike other excavation or demolition methods, polyjacking can be completed quickly and efficiently, saving time and money. Additionally, the polyurethane foam used in the process is lightweight yet incredibly strong, providing long-lasting support for your foundation.

The Polyjacking Process Explained

To better understand the polyjacking process, let’s break it down into essential steps. First, a thorough foundation inspection is conducted to identify the areas that require repair. Next, small holes are drilled into the concrete slab at strategic locations. The polyurethane foam mixture is then injected into the holes, and as it expands, it lifts and levels the foundation. Finally, the holes are filled and sealed, leaving a stable and secure foundation behind.

Polyjacking vs. Other Foundation Repair Methods

While several foundation repair methods are available, polyjacking has numerous advantages. When you compare mudjacking vs polyjacking, traditional methods such as mudjacking involve pumping a mixture of mud and cement beneath the slab. In contrast, polyjacking uses a lightweight and durable polyurethane foam.

This foam offers better lifting capabilities and is less likely to settle or erode over time. Additionally, polyjacking requires smaller and fewer injection holes, resulting in less damage to the concrete slab.

So, when you think about sidewalk lifting foam, it might provide longer results than concrete mudjacking.

Common Misconceptions about Polyjacking

There are some misconceptions surrounding polyjacking that need to be addressed. One common misconception is that polyjacking is only a temporary fix.

However, when performed by a reputable contractor using high-quality materials, polyjacking can provide a long-lasting solution to foundation settlement.

Another misconception is that polyjacking can cause damage to the plumbing or other utilities beneath the slab. The process is carefully controlled, and the foam is injected to minimize potential risks.

How to Choose a Polyjacking Contractor

also protects you from any potential liabilities. A reputable contractor should be more than willing to provide proof of their licensing and insurance upon request.

Ask about their polyjacking, mud jacking, foam jacking, or concrete mud jacking work warranty.

A contractor who stands by their craftsmanship will typically provide a warranty that covers any potential issues that may arise after the completion of the process. This warranty assures you of their confidence in their work and provides peace of mind.

Polyjacking Cost and Considerations

The cost of polyjacking, a method used to repair foundation settlement, can vary depending on several factors.

These factors include the size and complexity of the project, the extent of the foundation settlement, the accessibility of the affected areas, and the type of polyurethane foam used. Each of these elements can impact the overall cost of the polyjacking process.

You should get multiple quotes from different contractors to ensure you receive a fair price for your project.

This will allow you to compare prices and choose the best option for your budget.

However, it is essential to focus on something other than price when deciding. It is also crucial to consider the reputation and experience of the contractor.

While choosing a cheaper option may seem tempting, it could result in subpar artistry and potential future issues. Therefore, it is essential to balance cost and quality when selecting a contractor for your polyjacking needs.
