When it comes to repairing sunken or uneven concrete in Crystal Lake, two popular methods are often considered: concrete raising (using polyurethane foam) and mudjacking. Both aim to lift and level concrete slabs but differ significantly in materials, process, durability, and overall effectiveness.
Understanding these differences can help homeowners and businesses choose the best long-term solution for their concrete repair needs.
What Is Mudjacking?
Mudjacking, also known as slab jacking or pressure grouting, is a traditional repair method that has been used for decades. It involves drilling several large holes (typically 1 to 1.5 inches in diameter) in the concrete slab and pumping a slurry mixture of soil, water, sand, and cement underneath to fill voids and lift the slab back into position.
Pros of Mudjacking:
- Generally lower upfront cost than polyurethane concrete raising
- Proven technique with wide availability of contractors
- Effective for minor lifting or slabs in good condition
Cons of Mudjacking:
- Uses a heavy slurry (about 100 lbs per cubic foot), which can compact and destabilize soil further over time
- The material is not waterproof and can wash away or erode with water exposure, causing future settling
- Requires larger holes and more extensive surface patching
- Longer drying and curing time, delaying the use of repaired concrete
What Is Concrete Raising (Polyurethane Foam)?
Concrete raising uses a high-density, expanding polyurethane foam injected through small dime-sized holes (around 3/8 inch) drilled into the slab. The foam expands rapidly, filling voids and stabilizing soil with minimal added weight, lifting the concrete gently and evenly to its original position.
Pros of Polyurethane Concrete Raising:
- Lightweight foam reduces soil compaction risk and further settling
- Quick curing time (typically within 15 minutes), allowing near-immediate use
- Small holes and minimal surface disruption with small patches instead of large repairs
- Foam is water-resistant and durable, offering long-lasting stability
- Environmentally friendly due to less material waste and longer-lasting repairs
Cons of Polyurethane Concrete Raising:
- Higher upfront cost relative to mudjacking
- Requires specialized equipment and trained installers (fewer contractors offer this service)
Which One Is Right for Your Crystal Lake Property?
- Choose Mudjacking if: You have a smaller project, a limited budget, and your concrete slab is mostly intact without major soil instability.
- Choose Polyurethane Concrete Raising if: You want a more permanent, durable solution with minimal disruption, quick curing, and long-lasting results, especially on heavily settled or load-bearing slabs.

Frequently Asked Questions
Is polyurethane foam concrete raising more expensive than mudjacking?
- It usually costs more upfront but offers superior durability and less risk of future settling, making it more cost-effective over time.
How soon can I use my concrete after raising?
- Polyurethane foam cures in about 15 minutes, allowing immediate use, whereas mudjacking can take days to dry.
Are there large holes after foam concrete raising?
- No, injection holes are about the size of a dime (3/8 inch) and are patched to blend seamlessly with the concrete.
Can foam concrete raising be done on damaged concrete slabs?
- Severe damage may require replacement; Acme provides free inspections to recommend the best course.
Is polyurethane foam safe for the environment and the surrounding landscaping?
- Yes, once cured, the foam is inert, non-toxic, water-resistant, and safe for lawns, gardens, and pets.
