What Is Cellular Concrete?
Cellular concrete is a lightweight concrete made 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.
The result is a lightweight cellular concrete that is pumpable, self-leveling and self-compacting, which makes it well suited for 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 problems with weight, compaction, access or placement. Since it weighs less than traditional fill, cellular concrete puts less weight on the ground and nearby structures. It also flows into place without mechanical compaction.
Its pumpability also makes it practical in 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 Changes & Structural Fill
Lightweight Fill & Dead Load Reduction
Low-density cellular concrete cuts the weight added to soft or unstable ground, making it useful for embankments, grade raises and other large-volume fills. It can also be pumped across difficult sites, offering an efficient way to build up grades without hauling in and compacting large quantities of aggregate.
For Bridge Approaches, Abutments & Wingwalls
Bridge Approach & Abutment Backfill
Settlement at bridge approaches can create uneven transitions between the roadway and bridge structure. Lightweight cellular concrete reduces the weight carried by the soils below while also cutting pressure against abutments and wingwalls, making it useful for new bridge construction, approach reconstruction and rehabilitation projects.
For MSE Walls & Retaining Systems
MSE Wall & Retaining Wall Backfill
The weight of conventional backfill can put additional pressure on retaining walls and the soils supporting them. Cellular concrete offers a lighter alternative that reduces those loads and flows into place without heavy compaction equipment operating directly behind the wall.
For Tunnels, Casings, Culverts & Inaccessible Voids
Void Fill & Annular Space Grouting
Cellular concrete can be placed by pump into annular spaces, tunnels, casings, liners, culverts and irregular voids that are hard to reach with conventional fill. Its flowable consistency lets it move around obstructions and through confined spaces from a remote placement point. For voids beneath slabs and pavement, see commercial Polylevel injection.
For Decommissioned Infrastructure & Underground Voids
Pipeline, Tank & Mine Abandonment
Decommissioned pipelines, underground storage tanks, shafts and mine voids often have to be permanently filled before closure. Cellular concrete can be pumped into these enclosed spaces from grade or another accessible location, making it practical for filling large subsurface volumes without hauling conventional fill into the void.
For Pipelines, Conduits & Underground Utilities
Trench Backfill & Pipe Bedding
Cellular concrete flows around pipes, conduits, crossings and other buried infrastructure to create consistent trench backfill or pipe bedding. Since it doesn’t need to be placed and compacted in lifts, it can simplify backfilling in deep, narrow or congested trenches where working around utilities can be difficult.
How Legacy Supportworks Places Cellular Concrete in [Target Location]
Cellular Concrete vs. Other Fill Materials
Compared with select fill or compacted aggregate, cellular concrete is lighter, pumpable and eliminates 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 provides 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.
