Expansive Clay Soils and Vegetative Influences on Shallow Foundations: Proceedings of the Geo-Institute Shallow Foundation and Soil Properties Committee 

Expansive soils have the ability to drastically swell based on the amount of expansive minerals and moisture that is present in the soil. Expansive soils generally contain some form of clay mineral that is able to absorb water and swell when wet then shrink when dry. Expansive soil is characterized by clayey material. Treating expansive soil is necessary because clay soil particles attract moisture and hold on to it, producing a swelling mass of soil and water.

Expansive soils behave differently from other normal soils due to their tendency to swell and shrink. Expansive soils contain minerals such as smectite clays that are capable of absorbing water. When they absorb water, they increase in volume. The more water they absorb, the more their volume increases. Expansions of ten percent or more are not uncommon.

Expansive soil

Expansive soils are regarded as problematic soils as they affect the stability of structures founded on them. Hence, it becomes very essential for a practicing geotechnical engineer to expansive soil cohesive forces are developed up to a depth of about 1.0–1.2 m and counteract heave. CNS layer creates an environment similar to that around 1 m deep in an expansive soil with equivalent cohesion to counteract heave. In physical alteration, granular material is mixed with expansive … Expansive Soil: The hidden force behind basement and foundation problems Over 50 percent of these areas are underlain by soils with abundant clays of high swelling potential.

Ordinarily soil with high clay content, this dirt type is one of the main sources of foundation issues. CNT Foundations has answers for all your foundation repair needs. Engineering problems shunned previously rise to the surface gradually with the activities of reforming the natural world in depth, the problem of expansive soil crack under the changing environment becoming a control factor of expansive soil slope stability.
