Our fabric reinforced elastomeric troughs have been used in a wide variety of state and local bridge projects and can be fabricated to any state specification.
Common stock material includes polychloroprene (neoprene) and EPDM with nylon reinforcement.
Stock thicknesses are typically available in 1/8″, 3/16″, and 1/4″ .
Material thickness, including total number of plies is custom fabricated to any length and width with hanger plates, end caps, and downspouts as required.
