Enviro-Span is a significant innovation in stream crossings. The permanent or temporary culvert system suitable for use over fish bearing or environmentally sensitive streams without disturbing the streambed.

Culvert System

 Benefits

  • light-weight and strong as steel
  • stackable for easy transport
  • span and wedge sections can be placed in multiple configurations
  • flexibility to be installed on deep organics
  • installed consistently within three hours

 

Features

  • Patented, non-metallic, non-corrosive, non-leeching, and reusable
    permanent or temporary arch culvert system. 
  • Produced from liquid molding resin resulting in a durable non-metallic alternative to heavy metal culverts.
  • Available in span and elbow sections allowing for a precise following of the natural stream bed without additional disturbance.
  • Fininte Element Analysis confirmed per the following: the crown of the culvert is overlain by 0.91 m (3 ft.) of granular backfill and subject to a 307kN (69,000 lb) per axle load with tandem axle configuration (e.g. an L-150 off-highway logging truck).
  • Due to the lightweight material and innovative design, the bottomless culverts require less time, equipment, and manpower for environmentally friendly installations when compared to traditional stream and ditch crossing methods.
