e/Expansive clay

Information
has gloss	eng: Expansive clay is a clay that is prone to large volume changes that are directly related to changes in water content. Mitigation of the effects of expansive clay on structures built in areas with expansive clays is a major challenge in geotechnical engineering. Cities built on top of clay compact the clay beneath as groundwater is drawn down and water is wringed out of the clay. Rebound caused by heavy rain can destroy or crack buildings, and permanent land subsidence may occur in large cities with significant skylines.
lexicalization	eng: expansive clay
instance of	(noun) matter that has been deposited by some natural process deposit, sediment

Meaning
Castilian
has gloss	spa: Una arcilla expansiva es aquella arcilla susceptible de producir grandes cambios de volumen, en directa relación con los cambios en la humedad del suelo. La mitigación de los efectos de una arcilla expansiva en las estructuras realizadas en las áreas con arcillas expansivas es el mayor desafío en la ingeniería geotécnica.
