Sunken concrete slabs plague many property owners. Over time, erosion, shifting soil, compaction, and other factors lead to concrete settlement. As a result, neglecting this issue can cause structural damage, vehicle damage, trip hazards, and other liability risks. However, contractors skilled in leveling concrete with foam offer an efficient and effective solution.

Sunken Concrete Repair Options

Property owners can choose from three main options to repair sunken concrete:

• Replace the Slab: This messy, time-consuming, and expensive option involves removing and re-pouring the concrete.
• Mudjacking: Also called slab jacking with cement grout, this method requires heavy equipment and large drill holes. Furthermore, the cement may crack and sink again over time.
• Leveling with Polyurethane Foam: Contractors inject lightweight foam through small holes drilled in the slab. Subsequently, the expanding foam quickly raises the concrete with minimal invasiveness and long-lasting durability.

Why Polyurethane Foam is Ideal for Concrete Leveling

Several key benefits make polyurethane foam ideal for leveling sunken slabs:

• High Strength: Slab lifting foams deliver compressive strengths stronger than clay or bedrock. Moreover, the foam gains even more strength when injected under the slab.
• Fast and Efficient: Polyurethane foam slab jacking proves much faster than replacing concrete. 
• Minimally Invasive: The polyurethane lifting process requires smaller holes and lighter equipment than mudjacking or replacement.
• Lasting Results: High-strength polyurethane foams provide long-term durability and load-bearing capacity. 
• Environmentally Friendly: Alchatek's lifting foams are NSF-certified to strict environmental standards.

The Polyurethane Concrete Leveling Process

Contractors follow a simple 3-step process to level concrete with polyurethane foam:

1. First, they strategically drill 3/8" holes into the slab and install injection ports.
2. Next, they inject high-strength polyurethane foam through the ports.
3. Finally, the expanding foam beneath the slab fills voids and lifts the concrete back to a level position.

After lifting, contractors patch the drill holes and seal any cracks. Subsequently, the repaired concrete is ready for use about 45 minutes later. Depending on the size of the repair area, the entire process often takes just a few hours.
