Engineered Precast
Box Culverts
Box culverts provide a strong and efficient solution for stormwater management, waterway crossings, and roadway drainage. Made from high-strength reinforced concrete, they offer superior durability, load-bearing capacity, and versatility for various infrastructure applications. Their rigid design allows for easy installation and long-term reliability, even in high-traffic areas.
With our modular formwork, Coldstream Concrete can produce the span and rise required to meet your project specifications.
Chambers
Concrete chambers provide secure, long-lasting enclosures for stormwater, sanitary, and utility applications. Designed for durability and ease of access, they offer a robust solution for housing pumps, valves, and other infrastructure components. Their reinforced construction ensures resistance to environmental and structural stressors.
