What Are Concrete Culverts?
Concrete culverts are reinforced concrete structures designed to channel water, provide drainage solutions, and support roadways, railways, and pedestrian pathways. They are essential in civil engineering projects to ensure proper water flow and infrastructure stability.
Types of Concrete Culverts we can help manufacture:
- Box Culvert: Rectangular or square-shaped for stormwater drainage, tunnels, and underpasses.
- Pipe Culverts: Circular precast concrete pipes used for small-scale drainage.
- Slab Culverts: Flat, open culverts for low-traffic crossings and water flow management.
Macrete specialises in precast box culverts, offering faster installation, strength, and longevity compared to cast-in-situ alternatives.
Applications of Concrete Box Culverts
