Uneven concrete slabs can become safety hazards and eyesores, but polyurethane concrete leveling provides a fast, reliable fix without the expense of full replacement. Alchatek’s AP Lift foams make it affordable and efficient, with costs varying based on project size, site conditions, and location. Typically ranging from budget-friendly for small jobs to competitive for larger ones, it’s 50-70% cheaper than demolition and repouring.
Size of the Slab: Larger areas may require more material and labor. In contrast, smaller areas may be more straightforward.
Extent of the Damage: The level of cracking and sinking determines the most appropriate repair method. Minor issues may suit polyurethane leveling, while extensive damage might require additional repairs or replacement.
Condition of the Soil: A thorough evaluation of the soil beneath sunken slabs will reveal underlying issues contributing to the problem. These findings help determine the best action for a stable, long-lasting repair.
Why does size affect cost so much? Larger areas need more foam and time, but per sq ft rates drop for bigger jobs—contact a contractor for a detailed estimate.
Does soil type affect the cost? Yes, clay or wet soils could influence the price but it’s still cheaper than alternatives—free assessments cover this.
In what other ways does this process save money? It eliminates the need for permits and excavation fees.
