| LIFTING METHOD | Hydraulic controlled lifting through controlled pressure beneath the slab for precise adjustment. | Expansion-based lifting. Polyurethane foam expands beneath the slab, fills voids, and raises the concrete. |
| MATERIAL TYPE | Earth-based slurry material | Two-part polyurethane foam |
| BEST FOR | Large slabs including: Driveways, sidewalks, patios, garages, pool decks, shop floors, porches, walkways, and more. | Voids, lighter slabs, poor soil compaction, soil stabilization, certain foundation stabilization situations, and tight-access areas. |
| SUPPORT STRENGTH | 50 – 200 PSI support strength | 27 – 70 PSI support strength |
| INJECTION HOLES | Typically quarter-sized holes. | Typically penny-sized holes. |
| TURNAROUND TIME | Often usable shortly after completion depending on site conditions. Real-world turnaround time is often very similar to poly leveling. | Often usable shortly after completion depending on site conditions. Real-world turnaround time is often very similar to mudjacking. |
| ENVIRONMENTAL FACTOR | Non-hazardous, earth-based material. Environmentally friendly. | Chemical-based product that should always be installed properly and professionally. |
| CLEANUP & FINISH | We patch injection holes, cracks, and expansion joints. Cleanup and finish are included as part of the completed project. | We patch injection holes, cracks, and expansion joints. Cleanup and finish are included as part of the completed project. |
| MAIN ADVANTAGE | Strong support and precise control for lifting and stabilizing larger concrete areas. | Lightweight material and effective void filling for certain applications and stabilization needs. |
| BEST CHOICE DEPENDS ON | Slab size, soil conditions, drainage, weight of concrete, and long-term stability goals. | Slab size, soil conditions, drainage, weight of concrete, and long-term stability goals. |
