Gravel (kerikil) is an essential construction material that works together with sand and cement to create strong and durable structures.
Even though it looks like simple crushed stones, gravel plays a major role in almost every building foundation.
What Is Gravel?
Gravel is a collection of small stones formed naturally or produced by crushing larger rocks. It comes in different sizes depending on the type of construction needed.
Main Functions of Gravel
1. Making Concrete Stronger
Gravel is a key component of concrete.
The mixture (cement + sand + gravel + water) becomes stronger because the gravel adds density and compressive strength.
2. Creating a Solid Foundation
Before building a house, gravel is placed as a base layer for foundations.
It helps distribute weight evenly and prevents the ground from sinking.
3. Improving Drainage
Gravel has spaces between the stones, allowing water to flow through easily.
This prevents water accumulation under floors or foundations.
4. Road and Pavement Construction
Gravel is widely used as a stabilizing layer for roads, driveways, and paving blocks to keep them firm and long-lasting.
5. Preventing Soil Erosion
Gravel is placed around buildings, gardens, and slopes to control erosion and maintain soil stability.
Why Gravel Is Important
Gravel is critical in construction because it provides strength, stability, and proper drainage—three factors that ensure buildings last for decades.
