Everything around us is made of concrete, including residential and commercial structures. When business and residential owners notice uneven, crumbling, and cracked concrete, they start to ponder how to fix the damage.
Let’s start with a common inquiry: what exactly is polyjacking?
Concrete raising
A more advantageous option to traditional mudjacking is polyjacking. The method of leveling and raising concrete by substituting polyurethane foam for mud is known as polyjacking.
A polyjacking business pumps foam into the concrete through microscopic pores, causing the foam to spread into the slab. When the polyurethane swells, the concrete is raised evenly and naturally.
The best technique available to elevate and level sunken concrete is polyjacking. Polyjacking employs a high-density foam known as polyurethane in place of the conventional mudjacking method, which involves raising a submerged slab into position by filling the space beneath mud material.
To start off the discussion, let’s examine the top four distinctions between polyjacking and regular mudjacking:
Weight: Compared to conventional mudjacking material, polyurethane weighs 250–300 pounds less per yard. Why does this matter?
Less pressure is applied to the earth beneath the concrete when the material is lighter, which reduces shifting. Since shifting is probably the reason behind all of this work to begin with, who wants to have to redo the work in a short amount of time?
Reliability: The earth may sink due to the additional weight of the mud, necessitating a second trip to fix the slab.
Curing Time: After injection, polyurethane usually takes 15 minutes to fully cure. As a result, all treated regions might have complete accessibility within minutes, not days.
Aesthetics:The 5/8-inch drill holes used for poly infusions are minuscule. The effect is far less muddy and more aesthetically pleasing—you can’t even know the holes were. In summary, mud is filthy.
Why is Concrete Lifting Known by so Many Different Names?
As we previously said, although mudjacking as well as polyjacking are distinct processes, they are commonly used synonymously. Concrete sinking may now be repaired more effectively and efficiently using the two-part polyjacking procedure.
When looking for a means to elevate concrete, residents and homeowners most frequently turn to the conventional mudjacking method. Some of the most popular phrases related to the poly process, besides mudjacking vs. polyjacking, include poly foam, foam jacking, poly raising and mud lifting, and concrete lifting.
Mudjacking’s Drawbacks
Erosion, groundwater movement, and decaying soils are the reasons why concrete slabs sink. Mudjacking has several drawbacks even when it does function. Large drill holes, huge machinery, several trucks, and—most importantly—the possibility of only transitory results are all necessary.
Builders have discovered polyjacking, which is even more effective than mudjacking.
Benefits of Polyjacking
One truck, no large equipment, tiny drill holes, and a significantly longer lifespan are all that is actually needed for polyjacking. Among polyjacking’s advantages are:
- Extended-term resolution
- More robust
- Doesn’t require large machinery
- Smaller holes with the drill
- Dries and cures in minutes as opposed to days.
- Installable in any climate
- Won’t decrease when the weather changes
- Not too heavy to be a strain on the earth
After reviewing the benefits and drawbacks of the concrete lifting technique—mudjacking vs. polyjacking, let’s address the query:
What is The Procedure For Polyjacking?
Actually, the procedure is as simple as it gets.
- Make a small hole the size of a coin in the afflicted region. The hole is just 5/8″ in diameter.
- Underneath the failing concrete, inject a high-density foam (https://en.wikipedia.org/wiki/Foam) per directions. Setup for a home or company only takes a few minutes and the necessary equipment easily fits into a sprinter van. Big vehicles, filthy muck, or massive pieces of equipment are not necessary.
- As the foam rises, stabilizes, and expands, the technician will keep an eye on it.
- The procedure is very easy to follow, efficient, and fast.
Many people are still curious about how long polyjacking will last as they assess it.how long does it take to raise concrete with polyjacking?
The typical task takes one or two hours to complete. Depending on how severe the sinking is, the technique itself only takes around 20 minutes or so; however, preparation and cleaning take longer.
For What Reason do Locals Prefer Polyjacking to Mudjacking?
Because it may restore the concrete to a normal, even level while preserving its present degree of resilience, polyjacking is a popular and practical method. Additionally, the polyurethane will resist water incursion better than the mudjacking technique.
Is Polyjacking Applicable in Locations That Are Difficult to Reach?
Compared to mudjacking, polyjacking equipment and supplies are substantially smaller. Mudjacking has a substantial weight from the mud’s volume, and more workers are needed to do the work in addition to the larger tools and equipment that are required.
Mud weighs thirty times as much as poly (120 pounds compared to 4 pounds per cubic foot).
