The flowSPAN™ proprietary system by ECS is a design-build cast-in-place concrete structure that tackles culvert and bridge challenges. The flowSPAN™ system provides a cost-effective design and a durable structure. In addition, with the ECS cast-in-place system, the timeline from purchase order to project completion is significantly shorter than what you would endure with prefabricated parts. On your next project, delegate the specialized water management structures to ECS and free up the site contractor to focus on what they do best.

When to use flowSPAN™
flowSPAN™ stormwater conduit in place of precast or prefabricated box culvert
Because flowSPAN™ is cast-in-place, it adapts geometrically to many sizes and shapes. In addition, flowSPAN™ three-sided structures protect natural waterways and meet the rigid requirements mandated by both the EPA and the Army Corps of Engineers. flowSPAN™ can also match the surrounding environment by using form liners and concrete stain. The flowSPAN™ proprietary system by ECS offers a unique and sensible solution for your culvert and bridge needs.
