What Is Cellular Concrete?
Cellular concrete is a lightweight concrete produced with cement, water and preformed foam. The foam substitutes for the stone aggregate used in conventional concrete, creating millions of stable air cells that lower the material's density.
What results is a lightweight cellular concrete that is pumpable, self-leveling and self-compacting, making it well suited to a range of commercial and infrastructure applications.

When to Use Cellular Concrete on a Commercial Project
Cellular concrete is often considered when a project needs fill but conventional aggregate creates challenges with weight, compaction, access or placement. Because it’s lighter than traditional fill, cellular concrete places less weight on the ground and nearby structures. It also flows into place with no need for mechanical compaction.
Its pumpability also makes it practical for remote or confined areas, including abandoned pipelines, tanks, tunnels, mine voids and annular spaces that conventional equipment cannot easily reach.

Our Cellular Concrete Solutions
For Embankments, Grade Raises & Large-Volume Fill
Lightweight Fill & Load Relief
Low-density cellular concrete reduces the weight added to soft or unstable ground, making it a fit for embankments, grade raises and other large-volume fills. It can also be pumped across challenging sites, providing an efficient way to build up grades without bringing in and compacting large quantities of aggregate.

For Bridge Approaches, Abutments & Wingwalls
Bridge Approach & Abutment Backfill
Settlement at bridge approaches can create rough transitions between the roadway and bridge structure. Lightweight cellular concrete lowers the weight placed on the soils below while also reducing pressure against abutments and wingwalls, which makes it useful for new bridge construction, approach reconstruction and rehabilitation projects.

For MSE Walls & Other Retaining Structures
MSE Wall & Retaining Wall Backfill
The weight of conventional backfill can place additional pressure on retaining walls and the soils supporting them. Cellular concrete is a lighter alternative that reduces those loads and flows into place without heavy compaction equipment working directly behind the wall.

For Tunnels, Casings, Culverts & Difficult-to-Reach Voids
Void Fill & Annular Space Filling
Cellular concrete can be pumped into annular spaces, tunnels, casings, liners, culverts and irregular voids that conventional fill can’t easily reach. Its flowable consistency helps it travel around obstructions and through confined spaces from a remote placement point. For voids under slabs and pavement, explore commercial Polylevel injection.

For Abandoned Infrastructure & Underground Voids
Pipe, Tank & Mine Abandonment
Decommissioned pipelines, underground storage tanks, shafts and mine voids often need to be permanently filled before closure. Cellular concrete can be pumped into these enclosed spaces from the surface or another accessible location, which makes it practical for filling large underground volumes without hauling conventional fill into the void.

For Pipelines, Conduits & Buried Utilities
Trench Backfill & Pipe Bedding
Cellular concrete flows around pipes, conduits, crossings and other buried utilities to deliver consistent trench backfill or pipe bedding. Because it does not need to be placed and compacted in layers, it can simplify backfilling in deep, narrow or congested trenches where working around utilities is difficult.

Cellular Concrete vs. Other Fill Materials
Compared with select fill or compacted aggregate, cellular concrete is lighter, pumpable and requires no mechanical compaction. Conventional CLSM, or flowable fill, offers similar placement advantages but at higher densities, while lightweight aggregate still needs hauling, placement and compaction.
EPS geofoam offers greater weight reduction but requires block-by-block installation and site access. Material, transportation, labor and placement requirements all affect the overall cost of each option.
