Structural polyurethane foam is a versatile material employed in the process of lifting uneven concrete surfaces. This innovative technique involves injecting a high-density polyurethane foam beneath sunken or settled concrete slabs, expanding and solidifying to lift and level them. The foam's expansive nature allows for precise control, filling voids and compacting loose soil. This cost-effective and minimally invasive solution addresses sunken driveways, sidewalks, and foundations without the need for extensive demolition. It provides long-lasting support, resisting future settlement. Widely used in residential, commercial, and infrastructure projects, structural polyurethane foam lifting ensures efficient and durable concrete leveling, enhancing safety and aesthetics.
Polyurethane foam is commonly used in commercial applications to raise and level concrete and interior foundations through a process known as polyurethane foam injection or foam jacking. This technique offers several advantages over traditional methods like mudjacking. Here are some commercial applications for using polyurethane foam in this context:
Sidewalks and Driveways: Polyurethane foam can be injected beneath sunken or uneven sidewalks and driveways to lift and level them, providing a safer and more even surface.
Industrial Floors: Uneven floors in warehouses, factories, or other industrial facilities can be leveled using polyurethane foam to create a smoother and more stable working environment.
Parking Lots: Polyurethane foam is used to lift and level sections of sunken or uneven pavement in parking lots, preventing trip hazards and improving overall safety.
Interior Foundations: Polyurethane foam injection is often used to stabilize and lift interior foundations that may have settled or shifted over time.
Commercial Buildings: In commercial structures, polyurethane foam can be injected beneath interior foundations to address settlement issues, preventing further damage and ensuring structural stability.
Retail Spaces: Retail establishments with uneven floors can benefit from polyurethane foam injections to create a level surface for customers and staff.
Using polyurethane foam for raising and leveling concrete is a common practice in residential applications. This method is often referred to as polyurethane foam injection or foam lifting. Here are some key points regarding the application of polyurethane foam for concrete leveling in various residential areas:
Polyurethane foam can be injected beneath sunken or uneven concrete sidewalks and driveways to lift and level the surfaces.
The process is minimally invasive and does not require extensive excavation.
Uneven pool decks and patios can be leveled using polyurethane foam injection.
The lightweight nature of the foam minimizes the stress on the underlying soil and structure.
Polyurethane foam is also used for foundation repair and stabilization.
It can be injected into voids or gaps beneath foundations to provide support and prevent further settlement.
Quick and efficient: The foam cures rapidly, allowing for fast results.
Minimal disruption: Compared to traditional methods, polyurethane foam injection is less disruptive to landscaping and structures.
Long-lasting: The foam is durable and provides a stable base for concrete structures.
Small holes are drilled into the affected concrete surface.
The polyurethane foam is injected through these holes.
The foam expands, lifting and leveling the concrete.
After curing, the holes are patched, leaving a smooth and even surface.
