Concrete Raising Warranties in Chicago: Read the Fine Print (ACME = 10-Year Coverage)
Homeowners often assume a “warranty” means long-term protection—until the exclusions show up. In the Chicago suburbs, it’s common to see concrete raising or “mudjacking” warranties that sound generous but collapse under the Terms & Conditions. Here’s how to compare warranties for polyurethane concrete leveling (and avoid costly surprises).
Common warranty traps to avoid
“Lifetime” that’s really one re-lift. Some “lifetime” warranties quietly cap coverage at a single re-lift. If the slab drops again, the warranty is void—your “lifetime” just turned into 30 days.
Limited to “labor and materials.” If a contractor can simply prove their product is still under your slab, they may deny service—even when the slab has resettled.
Three-year “replacement” with fine-print pricing. We’ve seen language offering “replacement at regular price minus your mudjacking cost.” That’s not protection; it’s a coupon.
One-year coverage. If a company has decades of experience but only stands behind a lift for a year, ask why.
A fast checklist (before you sign)
Is the coverage period clearly stated—and long enough to be meaningful?
Does it cover re-raising if the area settles again (not just materials)?
Are the exclusions simple and reasonable (e.g., Acts of God), or a maze of loopholes?
Are there homeowner “conditions” that let the contractor void coverage?
Will the contractor document what’s covered in writing (not just in a sales pitch)?
ACME’s warranty—plainly stated
ACME Concrete Raising & Repair provides a 10-year residential warranty on polyurethane concrete raising. It’s designed to be clear and useful:
What’s covered: If a warranted area re-settles, ACME will re-raise it during the warranty term.
What it isn’t: It’s not limited to “labor and materials” and not packed with conditions meant to void your claim.
Reasonable exclusions: Standard exceptions (e.g., Acts of God) apply, but there’s no bait-and-switch fine print.
Why we can offer it: ACME uses commercial-grade, high-density polyurethane that’s inert and water-resistant. It supports the slab, cures fast, and doesn’t wash out—ideal for Chicagoland soils and freeze–thaw cycles.
Bottom line: Don’t judge a warranty by its headline. Judge it by what happens if the slab settles again. With ACME’s 10-year coverage, you get straightforward protection—written, simple, and built to back the work, not dodge it.
Frequently Asked Questions
When does a slab need to be replaced?
A concrete slab may need to be replaced in various situations, particularly when it is severely damaged or cracked. This decision is typically driven by the extent of the damage, as well as other factors such as safety concerns, structural integrity issues, and the overall condition of the concrete. A professional concrete raising estimator should be helpful in guiding you toward replacement options when it’s in your best interest to do so.
Unfortunately, full slab replacement is a more extensive and costly process compared to alternative methods like foam jacking. The process of replacing a slab can be time-consuming, lasting several days or weeks, disrupting daily activities for homeowners or businesses. It requires loud, heavy machinery which can potentially cause damage to surrounding structures and landscapes. Ultimately, the decision to replace a concrete slab or explore other repair options will depend on the specific circumstances of the situation. Consulting with a professional contractor is advisable to determine the most suitable course of action for addressing the issues with the concrete slab.
Why do concrete slabs like sidewalks and driveways become uneven?
Concrete slabs, such as sidewalks and driveways, can become uneven due to a variety of reasons. One common factor is the natural settling of the soil beneath the slab. As the soil shifts and compacts, it can result in an imbalanced weight distribution, causing sections of the concrete to sink and become uneven. Changes in moisture levels play a significant role in causing clay-rich soil to expand or contract, further contributing to the unevenness of the slab.
Poor installation practices can also lead to uneven concrete slabs. If the base beneath the slab is not properly graded and compacted during installation, it can result in an unstable foundation, eventually leading to settling and unevenness. Similarly, if the concrete mix used isn’t adequate, the slab could be weak and prone to cracking, further contributing to the unevenness.
Moreover, heavy usage over time can also cause concrete slabs to become uneven. Continuous exposure to overweight vehicles and other external factors can result in wear and tear on the concrete surface, leading to settlement, cracks, and uneven surfaces.
In conclusion, a combination of factors such as soil settling, changes in moisture levels, poor installation practices, improper concrete mix preparation, and heavy usage can all contribute to the unevenness of concrete slabs like sidewalks and driveways. Proper construction techniques and regular maintenance are essential in preventing and addressing these issues to ensure the longevity and stability of the concrete surfaces.
How long does Foam Jacking last?
Foam jacking is known for its durability, with a typical lifespan of several decades. In comparison, mudjacking tends to have a much shorter longevity, lasting only a few years. Foam jacking’s long-lasting quality makes it a popular choice for those seeking a reliable and durable solution for their concrete leveling needs.
How much does Foam Jacking cost?
The cost of foam jacking (polyurethane concrete raising) can vary depending on several factors such as the size of the slab, how far it’s dropped and the quantity of foam required for filling the voids. Typically, the expenses for foam jacking ranges between $10 to $25 per square foot. It is worth noting that while foam jacking may involve a higher upfront cost compared to mudjacking, it is a more economical and efficient method in the long run.
How does foam jacking work to level an uneven sidewalk or driveway?
Foam jacking (polyurethane concrete raising) is the best technique to level an uneven sidewalk or driveway. The process involves first drilling dime-sized holes into the affected slab to allow for the injection of polyurethane foam. This foam is then injected beneath the concrete slab using a specialized injection gun, filling voids and gaps created by sinking soil.
Once the foam is injected, it expands and spreads, lifting the concrete slab and providing stability by filling voids and providing proper support. After the foam injection process is complete, the drilled holes are patched with cementitious grout to give the area a clean and finished appearance. Within around 15 minutes of the repair, the leveled slab is ready for use. This process effectively restores the surface to its proper level and addresses any underlying issues that caused the unevenness.
What are the benefits of foam jacking compared to older methods?
Foam jacking offers several key advantages over older concrete repair methods. Firstly, foam jacking is a lot quicker and much more efficient, often completing the repair process in a matter of hours with minimal disruption. This contrasts with traditional methods that involve heavy equipment and mudjacking slurries, resulting in longer repair times and greater inconvenience.
Another benefit of foam jacking is that the material used is lightweight, which helps prevent further soil settlement issues. Unlike older methods like mudjacking that can add weight to the soil, foam jacking offers precise control over the lift and allows for accurate and long-lasting repairs without causing additional strain on the ground.
Polyurethane concrete raising leaves behind minimal mess and debris compared to traditional methods, making it a cleaner and more environmentally friendly option. Lastly, the cost-effectiveness of foam jacking is a major advantage. It is generally more affordable than completely replacing the concrete slab, making it a practical choice for homeowners and businesses looking to repair their concrete surfaces without incurring excessive costs.
