Inert soil

Excavated soil and inert materials are defined in article R541-8 of the French Environment Code.

These are soils and materials that do not change physically, chemically or biologically, and do not alter their environment. Inert materials do not decompose
do not burn or produce any other physical or chemical reaction. They are non-biodegradable and do not damage other materials with which they come into contact in a way that could pollute the environment or harm human health.
