01 · PREPARATION

Rebuilding a Smooth Profile for the Liner

Debris was cleaned out of the culvert. Where added concrete was 4 in. thick, #4 wire was installed. All section discontinuities were corrected by pouring concrete, with a finished 3:1 slope and a smooth finish.

The corners of the reinforced concrete box (RCB) section and the bottom of the masonry section were chamfered to a 6-in. radius so the FRP could follow the shape.
