Gravel (and other rocks) act as barriers that shun rain and other forms of precipitation away from a building's foundation. Another benefit of using rock for drainage is that exposed rock absorbs the heat from sunlight more than other materials like mulch. Rock then radiates this heat at night. This helps to melt ice more quickly and move ...

Pros of Gravel Backfill. Gravel compacts very well, provided you use a compactor. When putting down sand as a backfill, you want to keep it wet- easy to do and not a project requiring extra machinery. However, you need a compactor with gravel, which slams a heavy plate down on the rocks to pack them together as closely as possible.

Clay is dense and heavy, making it an excellent choice for backfilling solid ground. Frozen clay can crack and expand, moving the ground above it. There's no filtration through clay, which means it can be harmful to plants. Backfilling alternatives to clay include sand, concrete, dirt, and woodchips.
