Cohesive soils, like clay, exhibit greater strength and stability compared to non-cohesive soils, such as sand. They have a lower permeability which can help in preventing seepage and erosion, making them suitable for foundation construction. Cohesive soils also typically experience less settlement over time, providing a more stable base for structures.

What is the difference between cohesive and non cohesive soil?
Cohesive soil: A sticky soil, such as clay or silt; its shear strength equals about half its unconfined compressive strength. Non-cohesive soil: loose, sandy material which does not bond together very well. Therefore, cohesive soil is a better foundation than that of non-cohesive.
What is cohesive soil?
Cohesive soil is a type of fine-grained soil that has strong attractive forces between its particles due to its clay content. This results in cohesive soil having good load-bearing capacity and high water retention. However, cohesive soil can become very sticky and difficult to work with when wet.
What you mean by cohesive and non-cohesive soil?
Cohesive soil contains clay particles that stick together due to electrostatic forces, forming cohesive bonds. Non-cohesive soil, on the other hand, lacks clay particles and does not exhibit cohesive properties. The distinction between the two types of soil is important in geotechnical engineering for assessing factors like stability, shear strength, and settlement characteristics.
What is a non cohesive soil?
A non-cohesive soil is a type of soil that lacks cohesive properties, meaning it does not stick together and has low shear strength. This type of soil is typically made up of non-cohesive particles such as sands and gravels, which allows water to flow through easily and does not form stable structures.
Is clay soil cohesive?
Yes, clay soil is cohesive because its small particle size allows for strong molecular bonds to form between particles. This results in the soil sticking together and forming large clumps or blocks.
