Services
Box Culverts
Precast reinforced concrete box culverts provide efficient water conveyance under roadways. Built to Caltrans D-83 standards with AASHTO HL-93 load ratings, these modules feature self-aligning joints for faster installation. The precision wet-casting process creates smooth surfaces that enhance flow efficiency while maintaining structural integrity for heavy traffic applications.
Grease Interceptors
ASTM C1613 compliant grease interceptors prevent fats, oils, and grease from entering sewer systems. Available in 500-4000 gallon capacities with watertight construction, these interceptors use optimized baffling systems for superior FOG separation. Designed for California's strict environmental regulations, they feature durable concrete/steel construction and easy maintenance access points.
Storm Prism
Modular precast stormwater storage systems engineered for detention and infiltration. With heights from 3-14 feet and HS-20 load ratings, these customizable units feature unobstructed floors for easy cleaning. The system's modular design allows scalable implementation in urban and industrial settings while maintaining rapid installation capabilities through factory production.
EV Charging Foundations
Specialized precast concrete foundations for EV charging stations, including EVEZ series models with replaceable mounting plates. These durable bases support chargers weighing up to 3,000 lbs while incorporating cable management systems. Designed for rapid deployment with standardized dimensions that accommodate various charging unit configurations.
Reinforced Concrete Pipes
High-strength reinforced concrete pipes for stormwater and sewer applications. Available in 18-30 inch diameters with multiple joint options including rubber gaskets and tongue-and-groove connections. Manufactured to withstand heavy loads and environmental stressors, these pipes provide long-term durability for both public infrastructure and private development projects.
