Do you have sinking steps, a cracked driveway, a settled sidewalk or another concrete problem at your Utah home or business property? Discussing your options with a local company that specializes in concrete repair is a smart move, but you may want to learn more first – that way, you won’t enter the conversation unprepared.
Planning a concrete repair project can be a challenging task, but with the right knowledge, you can manage the matter with confidence. To get you started, we’ve compiled a list of commonly asked questions about concrete repair and maintenance practices.
What Causes Concrete Damage?
When a slab sinks, settles or cracks, the damage could be due to base construction errors – like too little or too much water in the concrete mixture or not allowing enough curing time. That said, most damage results from soil-related issues, such as significant changes in moisture levels, repeat freeze-and-thaw cycles and improper land grading.
Why is Concrete Repair Important?
Slabs with wide cracks and uneven concrete pose serious hazards to anyone who visits your Utah home or business property. Trips, painful falls and injuries can occur – and with that can come expensive liability claims. Also, by addressing the problem, you can keep the damage from escalating to the point where a more costly solution is required.
How Do Contractors Repair Concrete?
Concrete repair requires expertise and professional skill to properly execute, but the process is relatively simple. First, contractors use ground penetrating radar (GPR) to find empty spaces in the soil. Next, they drill small holes through the affected slab, reaching the soil voids. Then, using a hydraulic pump, they send a stabilizing material – either a cement slurry mixture or polyurethane foam – through the holes and into the subsurface voids. Once the spaces are filled, pressure lifts the slab back, restoring it to a stable and level position.
Which is Better — Mudjacking or Polyjacking?
Both can provide long-lasting results, but concrete repair by means of mudjacking, using the cement slurry mixture, is generally seen as the better choice. Not only does polyurethane foam contain additives that can be harmful to the environment, but the nature of the material – the way it expands after being injected and how it hardens more quickly than the cement slurry used in mudjacking – makes it difficult to raise a slab to the right position. Plus, with polyjacking, concrete repair is much more expensive, and while the drilled holes are slightly smaller than those needed for mudjacking, there’s very little difference after caulk has been applied. With all of this in mind, polyjacking is rarely the right solution.
How Long Does Concrete Repair Take?
The time it takes to repair concrete is dependent on several factors, including the scope of the underlying soil voids and the extent of slab damage. Most projects are finished within a couple of hours – and while that may seem like a long time, it’s nothing compared to a concrete replacement project, as that can take weeks. Furthermore, when repair work is done, the concrete is immediately ready for light use and capable of handling heavy weight by the next day.
Are the Holes Visible Afterwards?
After concrete is repaired, the drilled holes and any cracks in the slab are sealed to prevent water infiltration. Caulking also ensures that the holes become barely noticeable, particularly from a distance. Many of our customers must get close and search for the holes when looking at a repaired slab, as the concrete looks just like the surrounding slabs.
How Long Do the Results Last?
Because the concrete repair process addresses instabilities in the underlying soil, the results are long-lived. In Utah, most slabs that are repaired remain level and stable for at least ten years – and with proper caulking and periodic resealing, concrete may be problem-free for far longer.
How Much Does Concrete Repair Cost?
Expenses can vary, of course, which is why professional contractors provide customized concrete repair estimates based on the soil voids present, the size of the job, any difficulties in accessing the work area and additional services requested. According to HomeAdvisor.com, the cost of mudjacking typically runs between $661 and $1,846. The price for polyjacking is hundreds of dollars higher, as polyurethane foam costs four to five times as much as the cement slurry mixture used for mudjacking. Replacing a damaged slab is even more expensive, coming in at two to three times the total for a mudjacking project.
Is Concrete Repair Always an Option?
In Utah, professional contractors routinely repair cracked sidewalks, sunken patios, uneven driveways, lopsided garage floors, tilted parking lots and other outdoor slabs. However, when concrete shows a considerable amount of cracking, weathering or crumbling, the only fix may be replacement.
