Box Culverts can be cast in a wide range of sizes.

All Box Culverts are designed and manufactured to meet or exceed the requirements of the customer. These standards often include, but are not limited to ASTM C1433, AASHTO, Military and DOT requirements.

Culverts are wet cast in precision steel forms.

Many options are available to our customers, including:

• Openings for piping entering the culvert
  
  
• Openings in the top slab for Storm Inlets or Manhole Access.
  
  
• Conduit cast in to the corners to facilitate Post-Tensioning of sections
  
  
• Interior and Exterior Coatings
  Two component, epoxy, coatings are applied at the plant, when specified.

  Interior: "Ceramic White" epoxy for high performance, high build, and visibility within completed structure

  Exterior: "Enviro-Green" epoxy for high performance, high build, and aesthetically pleasing

• Butyl or Pre-Formed Neoprene Rubber for joint seals
  D-Lok Rubber Gasket for 48" and 60" diameter sanitary manholes (O-Ring for larger manholes). Compression design gasket manufactured in accordance with ASTM C-443 titled, "Joints for Circular Concrete Sewer and Culvert Pipe, Using Rubber Gaskets".
  Butyl Rubber for Round and Rectangular structures. Seal designed to meet requirements of ASTM C-990 titled, "Joints for Concrete Pipe, Manholes, Precast Box Sections Using Preformed Flexible Joint Sealants".
  Neoprene (1"x3/4") Gaskets are used to seal Box Culvert Joints
  
  
• Precast Concrete Channels
  Channels can be cast, at the plant, in round manholes, square structures, and box culverts. Channels provide laminar flow of liquids through our structure. A traditional manhole channel is formed up to the centerline of the pipe. A bench is formed with a pitch of 1:12 toward the channel. "Low flow" and "Fish" channels can be cast into box culverts as would be indicated on contract documents.
