Applications For Engineered Fill
Table of Contents
Engineered fill, also called low-density cellular concrete, cellular grout, or flowable fill, is a material that is highly flowable and both lighter and stronger than other types of fill materials, such as compacted soil. Because of its ability to flow easily into all spaces, engineered fill is often very cost-effective and is a great choice for a wide variety of applications. The low density and high strength of cellular concrete make it ideal for a wide range of stabilization, void fill, and underground projects, but here are some common projects that have used SERD engineered fill:
Transportation-Related Fills
Bridge approach fills: Engineered fill can be designed to decrease the local settlement on bridge approaches. Because of its durability and lightweight properties, it’s an excellent choice for load compensation in areas with weak soils or natural voids.
Roadway fills: Using lightweight cellular concrete creates a load-balancing base that distributes loads evenly across the pavement or path, increasing the resilience of roadways for long-term stabilization.
Plaza decks and parking garages: When your structurally supported plaza deck has specific load parameters or weight restrictions, low-density cellular concrete is a great choice.
Bridge Fill Approach
Landscape and Soil Stabilization
MSE retaining wall backfills: Using engineered fill helps to reduce the lateral load exerted against retaining walls and other landscape structures.
Soil stabilization: Evenly reduce loads over poor soils with cellular concrete. Based on the behavior of the geomaterial at your project site, we can modify the mix design to provide better durability and performance.
Weight-reducing fills and culvert fills: Cellular concrete provides excellent load reduction, crack prevention, and settlement control capabilities for culvert fills.
Landscaping and plaza fills: Engineered fill provides lightweight and stable properties to reduce soil load and allow for more creative landscaping design in plaza fill projects.
Soil Stabilization
Underground Encapsulation, Fills, and Insulation
Pipe trenching: For pipe trench and shaft fills, low-density cellular concrete is ideal due to its easy excavation, which can allow for future repairs.
Void fills, tunnel fills, utility fills, and mines: Because it’s highly flowable, cellular concrete can be pumped over great distances, taking care of underground void fills efficiently and effectively.
Underground fuel tank fills: Filling abandoned fuel tanks, such as gasoline, oil, and diesel tanks, is made easier with highly flowable engineered fill.
Thermal encapsulation and thermal remediation: Cellular concrete can provide a protective barrier of insulation, helping prevent thermal leakage or provide thermal remediation.
Tunnel Fills
