Intent of Work­To tie and bond separated facing stone to brick backup construction using Helefix Tie reinforcement and asolidifying injected grout.

Suitability­The work described herein is best suited for conditions where the collar joint mortar bonding behind the outer leafof stonework has deteriorated to a degree that all bond has been lost it can be removed and replaced, but thecondition of the outer leaf is sufficiently sound that will allow tie­back with frequently Helefix Ties without the needfor a supplemental dunnage system.
