Why Use
Low-Density
Cellular Concrete
(LDCC) Engineered
Flowable Fill
Quickly Fill Voids
No time to rework or finish adjacent surfaces? Need to save man hours and overall construction time?
The flexibility and lightweight material allows for the product to be placed in atypical perimeters without need for high manpower or lengthy
installation. The end product requires little to no maintenance and is easy to excavate.
APPLICATIONS: Tunnel/pipe annular fills and utility insulation fills. Abandoned Utility fills.
Soil Compressibility Issues
Some soil contains high organic material or soft clays that require compaction when using traditional Engineered Fill (EF) applications.
LDCC’s customizable mix designs allow load balancing that can be tailored to meet different densities and strengths as required for specific applications.
APPLICATIONS: Soil stabilization and unique-use design
Flood Prone Area & Settlement Issues
Traditional Engineered Fill (EF) applications have the risk of subsidence, erosion, or soil-instability. LDCC’s high strength to weight ratio provides low vertical and lateral forces and eliminates settlement and soil-instability issues. Resulting in a minimal load bearing option for increased elevation.
APPLICATIONS: Mechanically Stabilized Earth (MSE) and Reinforced Soil Slope (RSS) Wall Backfill and Landslip Repair
Tight Work Area
Cannot open the construction area for traditional concrete work? Physical restrictions or construction near inhabited or occupied dwellings.
Requires only small crew and can be pumped by small hoses for long distances even vertically if needed.
APPLICATIONS: Above parking garage plaza deck and elevated construction options.
Limited Project Duration
If you have a last minute need for an Engineered Fill (EF) application and need to compress your construction time, LDCC is an ideal solution. LDCC does not need compaction and can be quickly set up and pumped into location. No need for compaction. Workers do not need to be in the danger zone.
APPLICATIONS: Tight pipe trenches and pipe cribbing. Indoor trench fill where you cannot allow workers in trenches.
What Is Low-Density Cellular Concrete (LDCC) Engineered Fill?
Low-Density Cellular Concrete (LDCC), Cellular Concrete, or Controlled Low-Strength Material (CLSM) is a type of Engineered Fill (EF) that is a mixture of Portland Cement, water, and preformed foam. The foam creates a structure of discrete air cells within the concrete, increasing volume, reducing density, and improving flowability. Mix designs may use fly ash, sand, and other aggregates to achieve specific densities and strengths. These properties make Low-Density Cellular Concrete (LDCC) Engineered Fill ideal for a variety of geotechnical applications.
How Is Cellular Concrete Produced
and Placed?
Cellular Concrete or LDCC is produced on-site using a mobile batch plant and pumped into place. A slurry of cement and water is injected with preformed foam and can be pumped substantial distances making placement easier in confined and/or high-traffic areas. Daily production from mobile batch plants can exceed 2,000 CY/day and multiple batch plants can be utilized for high-volume jobs.
What Is Low Density - Controlled Low-Strength Material (LD-CLSM)?
Also called cellular concrete, engineered flowable fill, flowable fill, controlled-density fill, flowcrete, foamcrete, and liquid dirt, controlled low-strength material is a self-compacted cementitious material used primarily as a backfill in place of traditional compacted fill.

Applications for
Low-Density Cellular Concrete (LDCC) Engineered Flowable Fill
Tunnel/Pipe Annular Fills and Utility Insulation & Fills
When new utility piping is tunneled underground or installed in a casing, the space around it must be grouted. LDCC is highly flowable, ensuring these annular spaces are completely filled. LDCC has a very low set temperature compared to traditional grout, which protects the new pipe from heat damage. Buoyant forces are also reduced during grouting, due to LDCC’s low-density.
Soil stabilization and unique use design
MSE and RSS Wall Backfills
Plaza Decks and Parking Garages
Pipe Trenching Backfills and Shaft Backfills
Roadway Bases
Under the covering of asphalt paving most streets and roadways is 4-6 inches of granular rock or concrete material that can withstand the weight of traffic. With its lighter weight and lower density, LDCC is a perfect roadway substrate for areas with poor soils or where the road needs to be raised out of a floodplain.
Underground Fuel Tank Fills
Abandoned gasoline, diesel, and oil tanks beneath gas stations or rural areas can be up to 2-3 thousand cubic feet. LDCC is highly flowable and can be pumped from a substantial distance, making it a good solution for fuel tanks and other underground void fills.
Insulation and Isolation Barriers
The preformed foam mixed to create LDCC creates a structure of air pockets to guard against both thermal and acoustical changes. When used in walls, roofs, floors, or foundations, LDCC offers more heat and sound insulation than traditional concrete.
