Technosol

A Technosol in the World Reference Base for Soil Resources is a Reference Soil Group that combines soils whose properties and pedogenesis are dominated by their technical origin. They contain either a significant amount of artefacts (something in the soil recognizably made or extracted from the earth by humans), some sort of geotechnical liner, or are sealed by technic hard material (hard material created by humans, having properties unlike natural rock). They include soils from wastes (landfills, sludge, cinders, mine spoils, and ashes), pavements with their underlying unconsolidated material
