Grout Injecting Port Anchors
Port Anchors are part of a composite masonry stabilization system that does not just tie, but also bonds damaged masonry back together.John Wathne, founder of Voidspan Technologies
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.
Our anchors have Cintec socks at each and, along with threaded inserts for the installation of temporary dunnage to restrain against fluid pressure forces during grouting, as well as the ability to permanently fasten externally and internally applied supplemental reinforcements.
Port Anchors and be used in combination with Cintec Anchors with can also be purchased through VoidSpan for VoidSpan projects.
Unique Features of the VoidSpan Port Anchor
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).
Open Shank Port Anchor Installation
Rod Shank Anchors
for masonry consolidation and crack bridging with micro-fine, post-tensioning duct type, or fine flowable grouts where cleaning and flushing from the anchor is not required. Our standard anchors provide up to 7,500 lb confinement tension capacity.
Our “HC”-Type anchors, by special order, can provide as much as 100,000 pound tension capacity.
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.
