3/4 aggregate, commonly known as “Bahs 3/4,” is a medium-sized crushed stone material widely used in construction and infrastructure projects. It is produced by crushing larger rocks into uniform 3/4-inch particles, making it ideal for structural applications such as concrete production, road bases, and drainage solutions. Its high strength and durability make it a crucial component in modern construction.
Why You Should Use It?
High Load-Bearing Capacity: Supports heavy loads, making it perfect for road foundations.
Excellent Drainage Properties: Prevents water retention in construction projects.
Ideal for Concrete Mixing: Enhances the durability and stability of concrete structures.
Long-Lasting Material: Resistant to weathering and erosion.
Versatile Usage: Used in roads, landscaping, and retaining walls.
