Gravel vs. Laterite — What's the Difference?
By Tayyaba Rehman & Urooj Arif — Updated on March 31, 2024
Gravel is a versatile, coarse aggregate used in construction and landscaping, known for its rock composition, whereas laterite is a soil and rock type rich in iron and aluminum, formed in hot and wet tropical area, used primarily in building construction.

Key Differences
Gravel, consisting of rock fragments, is widely used for driveways, roads, and as a base material for concrete and asphalt paving. Its composition can vary widely, depending on the local geology, but typically includes rocks like quartz, granite, and limestone. Gravel provides excellent drainage and durability, making it ideal for various construction and landscaping projects. On the other hand, laterite is recognized for its rich iron and aluminum content, developing through the intense weathering of underlying parent rock in tropical climates. This weathering process results in a soil and rock type that, when hardened, becomes a strong, brick-like material used in construction, particularly in regions where it naturally occurs.
Gravel is typically categorized by size and can range from fine to coarse, with each size serving different purposes in construction and landscaping. It's sourced from river beds or quarried from rock deposits. Laterite, however, is formed in situ and is cut from the earth in large blocks or bricks, often used directly in construction without the need for processing or firing, which is a significant advantage in cost-sensitive and resource-limited areas.
The choice between gravel and laterite for a construction project depends largely on the project's location, intended use, and the materials' availability. Gravel's widespread availability and versatility make it a popular choice in a broad range of projects worldwide. In contrast, laterite's use is more geographically restricted to tropical areas where its natural formation occurs, such as parts of Africa, India, and Southeast Asia.
Environmental considerations also differ between the two materials. Gravel extraction can impact river ecosystems and landscapes, necessitating sustainable mining practices. Laterite, being directly cut from the earth, can also have environmental impacts, including deforestation and soil erosion, if not managed responsibly. However, its use can reduce the environmental footprint of construction projects by minimizing the need for processed materials and long-distance transportation.
Both gravel and laterite offer unique advantages for construction and landscaping, with their use reflecting local availability, economic considerations, and environmental impacts. While gravel provides flexibility and drainage benefits across various applications, laterite offers an eco-friendly building solution in specific climates, showcasing the importance of regional materials in sustainable construction practices.
