Discover The Best Way To Fix Uneven Concrete
Have you noticed your concrete patio or driveway cracking and appearing uneven? Uneven concrete isn’t just an eyesore — it may also impair the structure of your home. Fortunately, there are ways to address and repair this common issue.
Discover the difference between polyjacking and mudjacking — or mudjacking vs foam jacking — from The Crack Guys. Our foundation experts in both Alabama and Tennessee only use the best methods for concrete repair, so you can trust us to get the job done right.
How Do You Level Concrete?
- Polyjacking (Foam Jacking) — Uses lightweight, expanding polyurethane foam injected through small holes to lift and support the concrete slab
- Mudjacking (Slab Jacking) — Uses a heavy slurry (cement and soil blend) injected through larger holes to raise the concrete slab physically
Polyjacking vs. Mudjacking
- Durability — Polyjacking is generally considered more long-lasting and water-resistant.
- Cost — Polyjacking typically has a higher upfront cost than mudjacking.
- Cure time — Polyjacking cures rapidly (often in minutes), while mudjacking takes longer.
What Is Polyjacking (Foam Jacking)?
Our experts use polyjacking concrete when making repairs to the slab of your home. During the process, our team drills a small hole in the concrete and then injects polyurethane foam into the ground through it. This material helps thicken the base under the foundation slab.
After injection, the foam expands, filling any cracks or holes that cause the slab to sink. As a result, this process helps level out the concrete slab, which is vital when unevenness, sinking or settlement occurs. This process is also commonly known as foam jacking foundation repair.
Many foundation experts use polyjacking because it offers better support to the building and won’t break down due to moisture in the soil. With a durable material like this, you won’t have to worry about a repeat incident, nor will you have to replace the concrete slab quickly.
How Long Does Polyjacking Last?
Due to its durable and water-resistant nature, polyjacking typically provides a superior, long-lasting solution compared to traditional methods.
What Is Mudjacking?
Like polyjacking, concrete mudjacking helps lift a concrete slab and fill the cracks that caused the issue. However, the crack are filled with a blend of cement and clean soil, allowing the slab to rise to its proper level.
Why Pick Polyjacking Over Mudjacking?
You’re probably wondering which option is best since everyone wants to make the ideal restorations to their house to keep it in top condition. Both options repair your home but come with a few key differences. While mudjacking can be less expensive, it doesn’t last as long as polyjacking. Another difference between polyjacking and mudjacking is that mudjacking requires drilling more holes and takes longer to cure. So the timeline and stress of the project increase.
Although polyjacking (or foam jacking) may cost more upfront, it’s worth the price because it lasts longer. Additionally, mudjacking isn’t water-resistant, unlike polyjacking, which could result in recurring shifts in the future.
Polyjacking is well worth the higher price for a long-lasting peace of mind!
