Grout Injection Port Anchors
The grout-injecting VoidSpan Port Anchor is a stainless steel tie that can span internal voids to tie masonry together while providing an integral port through which voids can be inspected, cleaned, pre-dampened and grouted. Our anchors come in a wide variety of types and configurations and are custom fabricated to meet the specific needs of your installation.

Port Anchors and be used in combination with Cintec Anchors with can also be purchased through VoidSpan for VoidSpan projects.



Unique Features of Port Anchors
- All stainless steel construction -custom manufactured by Cintec America, LTD
- Application-specific designs to suit geometry, loading, grouting conditions and injection
pressures and lengths according to order - CINTEC sock anchors at one or both ends with bearing plates available in lieu of or in addition
to the socks - Removable threaded rods that can be socketed into the anchors’ outer ends for directattachment of permanent face plates, or temporary dunnage, if needed, to counter injection
pressures and minimize the need for external bracing - Double-ended anchors where face plates or dunnage are needed on both faces of the
masonry - Anchor-shear capacity based upon shear friction “haunch” theory, with the maximum tie
capacity provided at the point of best grout compaction and centered around the anchor - Economical and efficient design optimized for a 3-foot-by-3-foot (or one meter square) pattern
when tying and injection bonding inter-wythe collar joints using multiple lifts
Two Varieties of Port Anchors
Anchors are defined by series type, capacity and “A”, “B” and “C” dimensions that come from field measurements. We provide length calculation sheets with order forms, and engineering guidelines.

Open Shank Anchors
For collar joint applications that require cleaning, flushing and use of a fine flowable grout (such as VoidSpan PHLc Grout). The standard anchors provide up to 5,000 lb confinement tension and up to 3,000 lb “rolling shear” capacity (even discounting adhesion of the grout).

Rodded Shank Port Anchor Installation
CINTEC PRESSTEC GROUT is supplied with each anchor and must be used to fill the Cintec anchor socks. Any non-corrosive, non-metallic and ultra low-shrinkage grout, such as VoidSpan PHLc70,f can be injected through the VoidSpan anchor ports to fill the cavities and voids. Compatibility with the parent structure is critical to grout selection.

“Port Anchors are part of a composite masonry stabilization system that does not just tie, but also bonds damaged masonry back together.”
