Mudjacking, also known as slabjacking, is a low-cost, long-term solution for sunken or uneven concrete, but how long does it last? The response is that it depends on a few factors. How long did the concrete take to settle or sink? What is the age of your home? Was the settling caused by something external, such as downspouts or “critters”? What are the different forms of soil?
I usually ask the homeowner the questions above to get a sense of the situation or the likely causes of the settling concrete. Customers have had a 98 percent success rate in identifying the cause using this form of assessment in the past.Visit E&F Contracting Inc. – Sykesville Concrete Repair for more details.
Consider the first question: “How long did the concrete take to settle?” Frequently, the response is something along the lines of “it’s been that way for ten years.”
“How old is your house?” is the second question. Let’s say it’s a 25-year-old car. We’ve now established that the settling has been present for some time and that the house is not brand new. I can now answer the question “how long will the repair last?” after testing for environmental conditions as well as soils.
The mudjacking or concrete raising process should last 8 to 10 years. The amount of time it takes for concrete to settle is related to how long it will last. By injecting new material or grout under a slab of concrete, the soils that have hardened are replaced, and the concrete is now supported by new material. Grout is denser and more durable than existing soils.
If the response to my time query is “we only found that the walk settled in the last year,” I would presume there is an external trigger such as misdirected downspouts, critters, or erosion grading problems. If the house is less than 5 years old, the most common cause is soil settling as a result of construction disturbance. The final example is a hybrid of the first two, combining new construction with external factors.
If the triggers are reversed, such as eliminating critters, redirecting downspouts, or possibly installing or fixing gutters, the concrete raising will last 3-5 years. I’ve seen repairs last about a year if I just mud jack and the homeowner does not follow advice. Based on our 20+ years of mudjacking experience, the typical concrete repair is a long-term 5-7 year fix and money well spent.
