RCP & Precast Concrete
With a composite structure featuring the best of concrete and steel, reinforced concrete withstands both compression and tensile forces providing a long, worry-free service life.
AWWA C300, AWWA C361, ASTM C76
Manufactured with one of the most sustainable materials on earth, RCP (reinforced concrete pipe) and precast concrete products have a long life expectancy—often over 150 years. The premier choice for drainage and sanitary sewer systems, RCP supports both the weight of dead and live loads above. Valued in water infrastructure and utility projects, reinforced concrete structures are available in varying sizes and configurations designed specifically for your project.
We manufacture all of our concrete products in the controlled setting of our plants from locally sourced aggregates and cementitious materials with domestic steel. Our tight quality production and testing standards following ASTM and AASHTO specifications. Mastering the combination of mix design, computer-controlled batching, and the curing process, we add a bit of artistry to manufacture custom structures for your project.
Concrete is the world’s most commonly used building material and in its simplest form, is a mixture of Portland cement, water, and aggregate. Northwest Pipe Company manufacturers Reinforced Concrete Pipe (RCP) using concrete reinforced with steel cages and not pre-stressing wires. The composite structure marries the best features of concrete and steel reinforcement. The concrete manages compressive force while the reinforcement provides tensile strength.
Our Manholes and Fittings provide long-term structural integrity and safe access to confined spaces
