Epoxy Rock Bolt Failure

thread260-202938

Epoxy Rock Bolt Failure

Epoxy Rock Bolt Failure

(OP)
Besides the I-90 tunnel, does anyone know of any cases (small or large) where there was a failure associated with the use of epoxy rock/tension bolts?  I am looking for leads here, so anything helps!  

RE: Epoxy Rock Bolt Failure

i guess you're looking failures that resulted in death and/or litigation? not the sort of failure that resulted in re-installing the bolts during normal construction activity?
