Intent of WorkTo tie and bond separated facing stone to brick backup construction using Mini (small diameter) Port Anchorreinforcement and a solidifying 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 spaced Mini Port Anchorswithout the need for a supplemental dunnage system.
