Concrete lifting foam, often referred to as foam jacking, is a highly durable solution for raising and leveling concrete, capable of lasting 20 years or longer.
Durability of Concrete Lifting Foam
When you invest in concrete lifting, durability is a key concern. Polyurethane foam, the material used in foam jacking, is designed to be a long-lasting solution. Unlike traditional methods, this high-density foam expands to fill voids beneath concrete slabs, providing stable and enduring support. Its chemical properties ensure it remains inert and stable underground, resisting degradation from moisture, chemicals, or temperature fluctuations. This resilience is why foam jacking projects typically maintain their integrity for two decades or even more.
Benefits Beyond Longevity
Beyond its impressive lifespan, concrete lifting foam offers several significant advantages:
1. Rapid Repair and Usability
One of the standout features of foam jacking is its efficiency. Most concrete lifting jobs using foam take only a few hours to complete. Crucially, the treated concrete slab is often ready for immediate use, or at least within a few hours of the repair. This minimal downtime is incredibly beneficial for homeowners and businesses alike, allowing for quick resumption of normal activities on the leveled surface.
2. Foam Jacking vs. Mudjacking: A Comparison
To better understand the advantages of concrete lifting foam, it's helpful to compare it with an older, more traditional method: mudjacking.
| Feature | Foam Jacking (Polyurethane Foam) | Mudjacking (Cement Slurry) |
|---|---|---|
| Lifespan | 20 years or longer | A few years |
| Repair Time | A few hours | Typically longer |
| Cure Time | Slab ready for use in a few hours | Can take longer to cure |
| Material | Lightweight, high-density foam | Heavy, cement-based slurry |
| Holes Drilled | Small, less noticeable (typically 5/8") | Larger (typically 1-2") |
As the comparison highlights, while mudjacking might be a lower upfront cost, its shorter lifespan and longer repair times often make foam jacking a more cost-effective and convenient long-term solution. The lightweight nature of the foam also adds minimal load to the soil beneath, further contributing to its stability and preventing future settlement.
