Laterite

Definition

Laterite is a soil type rich in iron and aluminum, often formed in tropical and subtropical climates through the weathering of rocks. It is characterized by its reddish-brown color and is known for its use as a building material, particularly in monumental architecture across Southeast Asia. The properties of laterite make it an ideal choice for creating durable structures, as it hardens when exposed to air.
