Welcome to American Concrete Pipe Association - Northwest, the premier trade association representing manufacturers of concrete pipe and precast buried culverts including 4-Sided Box, 3-Sided and Split Culverts. Our commitment to excellence, resilience, and sustainability sets us apart as leaders in the precast concrete industry.


Resilience and Sustainability

Precast concrete stands as a symbol of resilience and sustainability. In an ever-changing world, our members contribute to the creation of durable, long-lasting infrastructure that withstands the test of time. The inherent strength and durability of precast concrete not only ensures the longevity of structures but also reduces the need for frequent replacements and repairs, thus minimizing environmental impact.

Moreover, our commitment to sustainability goes beyond durability. Precast concrete is inherently eco-friendly, as it can be produced with locally sourced materials, reducing transportation emissions. Additionally, the manufacturing process generates minimal waste, and the use of recycled materials further lessens our environmental footprint. As a trade association, we actively promote and support practices that prioritize environmental responsibility, ensuring a sustainable future for generations to come.
