What is a fill material in the construction context?

In the context of construction, a fill material specifically refers to soil or other types of materials that are used to raise ground levels. This material is typically placed in areas to create a level base for foundations, roads, or other structures. The purpose of using fill material is to improve the stability and load-bearing capacity of the ground, particularly in regions where the original soil is insufficient for supporting structures.

Fill materials can vary widely in composition, including natural soils, rock, gravel, and manufactured products. The selection of appropriate fill material depends on factors such as the intended use, soil conditions, and local building codes. Proper compaction of the fill is essential to ensure stability and prevent future settling or shifting.

While waterproofing materials, types of foundations, and mixtures for concrete have their respective roles in construction, they do not fall under the definition of fill materials, which is strictly focused on the practice of elevating or modifying ground levels.
