FILLFOAM™: The Smarter Way to Backfill Empty Underground Spaces in Atlanta and Alpharetta, GA

When it comes to repairing or stabilizing voids underground or beneath concrete, traditional backfilling methods like dirt or gravel just don’t cut it. They settle, wash out, and create new problems over time. That’s why Advance Concrete Lifting and Leveling offers FILLFOAM™, a cutting-edge solution for safely and permanently filling underground spaces in the greater Atlanta and Alpharetta, GA area. This innovative foam product is designed to provide lightweight, strong, and lasting support in even the toughest soil and water conditions.

What Is FILLFOAM™?

FILLFOAM™ is a high-density, structural polyurethane foam engineered to fill voids and cavities of almost any size. Once injected, it expands to fill the space completely, then hardens into a durable, water-resistant material. Unlike traditional fill materials that require excavation, FILLFOAM™ can be installed through small injection ports, allowing for quick, non-invasive applications.

Advance Concrete Lifting and Leveling uses professional-grade FILLFOAM™ systems to handle a wide range of projects, from residential void fills under driveways to large-scale municipal and industrial work.

Common Applications of FILLFOAM™

FILLFOAM™ is versatile, making it ideal for a variety of underground stabilization and void-filling situations across Atlanta’s unique mix of clay-heavy and erosion-prone soils. Here are just a few common uses:

• Sinkhole Repair – FILLFOAM™ can stabilize and fill sinkholes, stopping further ground movement and preventing damage to nearby structures.
• Abandoned Utility Lines and Pipes – Safely fills and seals old or unused pipelines, preventing collapse or groundwater infiltration.
• Void Fills Under Roads and Pavements – Perfect for restoring support beneath highways, parking lots, and airport runways where washouts or subsurface erosion have caused gaps.
• Culvert and Storm Drain Backfill – Reinforces deteriorating or damaged drainage systems without the need for full excavation.
• Bridge and Tunnel Stabilization – Provides lightweight support under structures that can’t handle the added load of traditional soil fill.
• Soil Stabilization and Erosion Control – Reduces settlement and strengthens weak soils to prevent future washouts or collapse.
• Basement and Foundation Support – FILLFOAM™ can be used around foundations or crawl spaces where voids have formed due to water erosion or poor compaction.

he Benefits of Using FILLFOAM™

Traditional backfill materials can be heavy and contribute to further settlement or instability. FILLFOAM™ is incredibly lightweight—up to 50 times lighter than soil—so it adds minimal stress to surrounding structures while still providing strong, uniform support. Other benefits include:

Fast, Non-Invasive Installation

With FILLFOAM™, there’s no need for large-scale excavation. The foam is injected through small holes and expands to fill every void, even in hard-to-reach areas. That means faster project completion, less site disruption, and lower labor costs.

Water-Resistant and Long-Lasting

Unlike soil or aggregate fill, FILLFOAM™ does not absorb water, wash away, or erode. It creates a permanent barrier against moisture and resists chemical degradation—an important advantage in Georgia’s rainy climate.

Environmentally Safe

FILLFOAM™ is environmentally friendly and non-toxic once cured. It will not leach harmful chemicals into the ground or groundwater, making it safe for residential, commercial, and municipal use.

Customizable Density

Depending on the project needs, FILLFOAM™ can be formulated in different densities to provide the perfect balance of strength, flexibility, and expansion. This adaptability makes it ideal for everything from delicate restoration work to large-scale infrastructure stabilization.
