Crusher Dust is commonly used as a foundation under paving, concrete slabs, hard-stand or wherever compacted fill is required. Crusher Dust is useful as a base for laying down pipes and serves as an ideal solution to stop soil from being waterlogged.

Crusher dust can contain minerals that are insoluble to water, which makes it an ideal material to stop mineral leaching in soils; to reduce waterlogging, and to raise the pH levels of the soil. Using crusher dust in horticulture can also aerate the soil and facilitate root growth.
