Is laterite soil good for construction?

Yes, laterite is an excellent material for construction, especially in the tropical regions where it is abundant.

Its key advantage is its ability to undergo a process called "irreversible hardening." When underground, it is soft and can be easily excavated and cut into desired shapes. Once it is exposed to the atmosphere and goes through wet and dry cycles, it hardens like rock. This property makes it a cheap and resilient material for building walls and foundations. Buildings constructed from laterite blocks are known for their durability and natural insulation properties.
