Concrete repair is a more efficient and cost-effective alternative to concrete replacement. With the development of treatments like Mudjacking and Polyjacking, concrete repair is easier than ever. Knowing which solution is best for your concrete needs can be difficult, though. That is why we have this comparison here.
What are Mudjacking and Polyjacking?
Although concrete is a strong material that’s ideal for construction, it can also be damaged. Sometimes the issues arise due to soils compacting under the weight of the concrete; other times they’re caused through erosion. If you notice sunken or uneven concrete on your property, you might be considering concrete replacement. But did you know you can cut replacement costs in half by repairing damaged concrete slabs through Mudjacking and Polyjacking?
Also known as “Pressure Grouting” or “Slabjacking,” Mudjacking and Polyjacking is a cost-effective method of mending concrete problems. In particular, it is used to lift concrete slabs that shift as the concrete naturally settles. It can also be used in larger foundation repairs as the construction settles. Rather than completely replacing a damaged area, you can use Mudjacking and Polyjacking to repair the specific areas.
How does it work?
In Mudjacking and Polyjacking, Polyurethane or a mud-like sand mixture (Proprietary Blend), also called “slurry,” is prepared. During the Mudjacking and Polyjacking process, an experienced professional will drill small holes into the sunken concrete slabs. Once the slurry is prepared, it is injected under the lifted slab in order to lift and stabilize the damaged region. When the concrete is raised to the right level, the holes drilled in the slabs are patched. Once cured, the slurry creates a solid base for the concrete slab.
When should you use these?
There are two main applications appropriate for Mudjacking and Polyjacking: To Fill a Void Under a Concrete Slab.
When your concrete develops a void under it whether it is a small void (1”) or a large void (4-24”), consider Mudjacking and Polyjacking to fill those voids. You can contact a concrete professional who can use Mudjacking and Polyjacking to fill the empty spaces and lift and stabilize your concrete.
To lift settling concrete slabs
For non-load bearing concrete slabs that are settling, Mudjacking or Polyjacking is also the appropriate solution. Again, a concrete expert can inject the slurry under the concrete, lifting and stabilizing the slab.
How long does Mudjacking take?
The amount of time spent on Mudjacking and Polyjacking obviously depends on the amount of damage on your property and the size of the project. Smaller Mudjacking and Polyjacking jobs can be completed in just a few hours, while more extensive projects will take a whole day to complete.
Once the slurry/poly is injected, it should remain undisturbed long enough for the holes that were patched to cure before it bears any load.
Concrete repair: Mudjacking vs. Polyjacking
Mudjacking
Cost
Tearing out existing concrete and replacing it is costly. Many concrete repair issues can be resolved through Mudjacking, though, which is a much cheaper alternative. Comparatively, industry experts estimate that Mudjacking can save you an estimated 50-75% vs. concrete replacement.
Solutions
Mudjacking can solve a range of problems like un-level concrete pads, sunken steps, uneven sidewalks, and the uneven joints in concrete pads.
When it comes to resolving these issues, this solution is as easy as one, two, three.
Process
This three-step process is simple and effective. First, series of holes are drilled into the problem area of concrete. Next, sand-based grout (proprietary blend) is pumped under the same slab, raising the area to the desired height. Then, the drilled holes are patched with cement. Once this last step is completed, your concrete will be ready after the hole patches have dried.
Efficient
In addition to saving you money, Mudjacking will save you time. When you choose this concrete repair solution, you will eliminate the time and cost of demolition, removal of materials, and the re-landscaping of surrounding areas. This concrete solution is so effective, that most projects are completed within one day, in fact, most are in a couple of hours.
Polyjacking
Another great concrete repair alternative is Polyjacking (polyurethane concrete lifting). This option is ideal for individuals who are looking for the most efficient and non-invasive procedures. If you want to save on time and improve the overall appearance of your concrete surface, Polyjacking is an absolute must.
Smaller Holes
The holes drilled during this process are much smaller than are those produced from Mudjacking. In fact, the 3/8″ & 5/8” injection holes that are drilled into your concrete are so small that you will hardly notice them once they are patched.
Fewer Holes
Since Polyjacking goes in as a liquid it will spread much further than traditional Mudjacking; therefore requiring less holes drilled in a slab.
Moisture-Resistant Properties
Need a concrete repair made in an area that is exposed to moisture frequently or how about an area that is submerged in water? When it comes to moisture, this material is up to the job. It is not only resistant to water. It can be applied underwater or in places that are exposed to high levels of moisture. Because of this characteristic, this concrete repair solution will hold up longer over time.
Erosion Proof
Polyurethane will not degrade over time since it is hidden from the UV light under the slab, it will essentially last forever. It will never erode or wash out.
Time
In addition to being a more durable and attractive alternative, this is also a quicker process. In a matter of hours, this process can be completed, leaving your concrete ready in no time. Have a time restriction? No problem! Your concrete repair will be completed in no time!
Conclusion
If you have a slab of concrete that needs repair, consider one of these effective alternatives before you turn to concrete replacement. Both Polyjacking and Mudjacking will save you time and money. When it comes to concrete repair, it is important that you take the time to determine the option that is best for your needs.
