While concrete is long-lasting, it does not stay in good condition forever. Old concrete is prone to damage, such as sinking, cracking, or unevenness. A cost-effective way to fix these issues is through concrete leveling. Polyjacking and mudjacking are the two most common concrete leveling methods today, and while these two concrete leveling methods share many similarities, it’s important to understand their differences, especially when deciding which best suits your needs.
At Smouse Brothers, we offer top-of-the-line concrete polyjacking services in Southwest Missouri. Keep reading to see the difference between polyjacking and mudjacking and which is better for your home today!
What is Polyjacking?
Polyjacking, or polyurethane injection, is today’s most popular concrete leveling method. It is a newer concrete leveling form that involves injecting liquid foam via small holes drilled into a concrete slab. After the foam is injected, it goes through a chemical reaction, causing it to expand. As it expands, it fills the gaps and exerts enough pressure on the slab to make it level again. The polyurethane foam hardens quickly, leaving you with level, stable concrete.
Pros of Polyjacking
Some of the benefits of polyjacking include:
- Smaller drill holes: The holes required for polyurethane injection are smaller than the ones needed for mudjacking.
- Time: Polyurethane foam hardens quickly, and the site can be ready for use in as little as 15 minutes.
- Lightweight: Polyurethane foam weighs around 2 pounds per cubic foot.
- Waterproof: Polyurethane foam is hydrophobic and will not wash away.
Cons of Polyjacking
- Higher cost: Polyjacking is more expensive due to the high cost of polyurethane.
- Less control: Since polyurethane expands, you need precision to fill the voids.
What is Mudjacking?
Mudjacking uses a mixture of soil, sand, clay, cement, and limestone. This mixture is pumped into drilled holes at high pressure and speed to fill the gaps. This mixture eventually builds enough pressure to raise the slab to a level position.
Once the process is complete, the holes are closed, and the area can be used again after 24-72 hours.
Pros of Mudjacking
Mudjacking has the following advantages:
- Cost-effective: Mudjacking generally costs less than polyjacking, making it a cost-effective leveling method.
- Strength and durability: Mudjacking lasts long when done by a knowledgeable concrete leveling expert.
Cons of Mudjacking
Mudjacking has the following disadvantages:
Drill hole size: When mudjacking, the process requires fairly large drill holes about two inches in diameter.
High pressure: The mudjacking process involves using high pressure to fill voids, which may lead to some not getting filled, causing a weaker repair.
Mudjacking Vs. Polyjacking, Which is Better?
Appearance
When polyjacking, the holes drilled into the concrete slabs are fewer and smaller. Mudjacking, on the other hand, requires more holes that are much larger. Ultimately, polyjacking results in a cleaner, more polished look.
Expedited time
Polyurethane takes minutes to cure and can be ready to be walked or driven on that same day. Mudjacking, on the other hand, can take 24 to 72 hours to cure and does not allow any traffic to use the fixed concrete during that time frame.
Water and moisture resistance
Polyurethane can be used in wet conditions or underwater. The foam-like material creates a barrier resistant to water and moisture penetration. Mudjacking, on the other hand, isn’t hydrophobic, so it doesn’t protect your concrete from water and moisture, leaving it at risk.
Weight
Concrete problems are typically a result of poor soil conditions. As such, you need a lightweight substance to deal with these issues to avoid further weakening the soil. Mudjacking typically weighs about 100 lbs per cubic foot, while polyurethane weighs 2-4 lbs. per cubic foot, making it an ideal option.
For the above reasons, polyjacking is undoubtedly a better option for concrete leveling.
