Laterite is a surface deposit of red or brown clay or soil that contains onthe surface of the rocks and was produced by decomposition. Richin and iron is found in many tropical regions, especially in India, Sri Lanka, and Burma. In India, British East Africa a calcareous laterite with a high lime content is called Kanka and has been used in the construction of bridges and other large engineeringworks because it works as a hydraulic cement. Laterites are often a poor soil, low fertility, and are often used as clay for making tiles, and as a rough work mortarin.
laterite, soil layer that is rich in iron oxide and derived from a wide variety of rocks weathering under strongly oxidizing and leaching conditions. It forms in tropical and subtropical regions where the climate is humid.Laterite being a major resource in the tropical, humid parts of the world by its varied uses contributes to the general economy
(i) as mineral ore – possible source of aluminum (Africa), iron (Goa and Canara), and nickel (Indonesia),
(ii) as substrate in aquatic structures like ponds and reservoirs,
(iii) as alternative building material for low cost housing (stabilized brick using laterite soil),
(iv) In road construction – as road substrate stabilized with fly ash and lime, and
(v) as a masonry material like other stones.

Laterite and associated soils are widely distributed in the tropics and subtropics of Africa, Australia, India, South-East Asia, and South America.
The word “laterite” has been derived from the Latin word “later” meaning brick (Gidigasu, 1974). Laterite is an unusual soil which is rich in iron and alumina.
Laterite and laterite soils have been efficiently utilized in civil engineering applications like road base and low cost housing.
