Flowable Fill and Cellular Grout
What is Flowable Fill?
Also called lightweight cellular concrete, cellular grout, low-density cellular concrete (LDCC), or controlled low-strength material (CLSM), engineered flowable fill 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 cellular grout ideal for a variety of geotechnical applications.
Applications of Flowable Fill
Cellular Grout’s strength, low density and extreme flowability make it an ideal solution for a variety of applications, especially for projects with soil compressibility issues, flood prone areas or tight work areas. Nettles uses cellular grout for tunnel/pipe annular fills and utility fills, soil stabilization and load reduction mitigation, MSE and RSS retaining wall backfills, plaza decks and parking garages, pipe trenching, roadway bases, underground fuel tank fills, insulation and isolation barriers and more.
