    Does anyone have any experience with failures of the drum grout at the skirt to structure support connections? 
    We are seeing the grout “turn to rubble” after 10-12yrs of service.  One thought is that there could be excessive horizontal movement causing the grout to be broken down.  Are there any other causal factors? 
    Thanks in advance.
