Mudjacking and polyurethane foam injection are the two primary methods often considered when it comes to concrete leveling. A crucial factor in choosing between them is understanding their longevity and how each method aligns with your long-term property maintenance goals.
Mudjacking: Traditional Approach with Limitations
Mudjacking involves injecting a slurry of cement, soil, and water beneath a sunken concrete slab to raise it to its original position. While this method has been in use for decades, its lifespan is generally shorter. Typically, mudjacking repairs last between 2 to 5 years. The primary reasons for this limited durability include:
-
Erosion Susceptibility: The slurry mixture is prone to erosion, especially in areas with poor drainage or heavy rainfall, leading to potential resettling of the concrete.
-
Heavier Material: The weight of the mudjacking material can further compress unstable soil beneath the slab, potentially causing additional settling over time.
Polyurethane Foam Injection: Modern, Long-Lasting Solution
Polyurethane foam injection, or polyjacking, utilizes a lightweight, expansive foam to lift and stabilize concrete slabs. This method offers several advantages in terms of longevity:
-
Extended Lifespan: Properly executed polyurethane foam repairs can last 20 years or more, often matching the remaining lifespan of the concrete itself.
-
Moisture Resistance: The foam is resistant to water infiltration, reducing the risk of erosion beneath the slab.
-
Lightweight Nature: Being significantly lighter than mudjacking slurry, the foam minimizes additional stress on the underlying soil, decreasing the likelihood of further settling.
Sealtite Insulation & Slabjacking: Commitment to Durability
