We have a project that requires installing threaded rod inti Terra Cotta slab and need to know which epoxy to use

Hi Joseph,

Unfortunately, Hilti does not have any adhesive anchoring systems approved for installations into terracotta base materials. The decision to use one of Hilti's adhesives for such an application would ultimately be at the discretion of the Engineer of Record on the project.

For additional assistance, please reach out to hnatechnicalservices@hilti.com or give us a call at 877-749-6337.

Regards,
Matthew
