What is Mudjacking and Polyjacking?

Mudjacking and Polyjacking are both two forms of concrete repair that are frequently used in the industry. However, in our years of experience, we’ve come to see that one is more reliable than the other.

Mudjacking

Mudjacking, also known as slabjacking or concrete lifting, is a traditional method of foundation repair. It involves injecting a mixture of soil, water, and cement under a concrete slab to lift it and level it. While mudjacking has been used for decades, it does come with some limitations.

Polyjacking

Polyjacking, on the other hand, is a more modern approach. It utilizes high-density polyurethane foam injected beneath the concrete. This foam expands, filling voids and lifting the concrete back into place. It's lighter, more durable, and less invasive compared to mudjacking, making it an attractive choice for many.

Common Problems With Traditional Mudjacking

Is mudjacking a long-lasting solution?

Mudjacking can be effective in the short term, but it often falls short in the long run. The mixture used can erode and settle, causing the same issues to reoccur over time.

Does mudjacking create a mess?

Mudjacking involves drilling holes into the concrete, which can be messy and may damage surrounding areas. Additionally, the heavy slurry used can put pressure on the soil, potentially leading to future settling.

Why Polyjacking Is The Better Choice

Durability and Longevity

Polyjacking takes the lead when it comes to durability and longevity. The polyurethane foam is incredibly stable and resistant to erosion. It won't break down over time, ensuring a long-lasting solution.

Less Intrusive

Polyjacking is a less invasive process. The smaller injection holes mean less disruption to your property, and the lightweight foam exerts less pressure on the underlying soil.

Lightweight Material

Polyurethane foam is remarkably lightweight compared to the heavy mixture used in mudjacking. This lightness doesn't put unnecessary stress on the foundation, reducing the risk of future settling.

Environmentally Friendly

If you're environmentally conscious, polyjacking is an eco-friendly choice. The process generates minimal waste, and the foam itself is environmentally safe.

Which Is More Cost Effective?

While polyjacking can have a slightly higher upfront cost than mudjacking, it's essential to consider the long-term savings. With its durability and minimal maintenance needs, polyjacking can be more cost-effective over time, reducing the likelihood of future repair expenses.


If you’re on the fence, we want to make it clear that polyjacking is a service that is well worth the initial investment. Not only will it repair what was damaged, but it will also give you the peace of mind knowing that no further repairs should be needed for a very long time.
