Fill Materials that can be Used for Construction Projects

Coarse-Grained Soil

Coarse-grained soil is one of the most popular backfill materials around. It’s composed of a mix of various sandy soils, different types of gravel, or a mixture of the two materials. This particular type of filler is frequently used in areas that require a certain amount of compaction and support for the foundation. It’s also useful in areas that need proper drainage.


Crushed stone or rock is another popular fill material. Certain projects, like the construction of septic tanks or dams, require proper drainage. Rock fill material accommodates runoff so that water does not back up and overflow these systems.

Rock and crushed stone are also commonly used to create a compacted base in the construction of driveways. In landscaping projects, crushed stone is often used as a filler to guarantee maximum drainage, while protecting against erosion.

Fine-Grained Soil

Fine-grained soil is often used as fill material in construction projects because it can be easily compacted to create a firm, solid foundation. It is one of the most popular materials used, even though it is not an ideal option for areas that have major drainage needs.

Commercial Byproducts

There are many types of natural materials used as fillers for different construction projects. However, when these resources are not available, commercially-made materials can be used as an alternative. One of the most common fill options is slag and ash, which is known for its overall versatility. Slag and ash can also be combined with clay to create a plastic fill material for use in certain projects.
