What is non-cohesive soil?

Answer 1

Sand type (not clay type) soil

Any free-running soil, like sand or gravel, whose strength depends on friction between soil particles is considered non-cohesive soil.

Cohesive soil, such as clay, can hold a significant amount of water and, when dry, hardens to a matrix that resembles cement. It also prevents water movement.

Non-cohesive soil lacks cohesive properties due to the absence of clay minerals, resulting in poor particle adhesion. This type of soil is prone to erosion and has low stability.
