After an especially active hurricane season, we saw several pipes like this in the Piedmont of the Carolinas. Infiltration and exfiltration during the storm caused undermining, which led to the downstream sticks becoming destabilized, as the pack under them washed away. With the pack that was supporting those downstream sticks gone, only the bell and gasket were holding the run of RCP together. Eventually, the last stick fell away and rolled downstream into the creek below. In this case, we reattached the separated stick and spincast the whole RCP to create a new pipe within the existing RCP. We added extra support and thickness, and replaced the washed-out fill (pack) with expansive, structural grout.
