VoidSpan Technologies, LLC is the supplier of a unique grout and sock-anchor based restoration system for existing masonry structures. We equip, train, and certify contractors to effectively use our system on a variety of applications including injection grouting, composite anchoring, deep pointing and localized rebuilding and repair.
Noted projects over the last ten years have ranged in scope from row houses and headstones to the NJ Statehouse, the University Center tower at Lehigh University, the Napa County Courthouse in Napa CA, and Fort Wood at the Statue of Liberty.
In collaboration with Cintec Reinforcement Systems, our patented Port Anchor was originally invented in 2010 to solve a stabilization problem for which no conventional solution previously existed, needing to simultaneously tie and bond a delaminated wall pier together under a 499,000 lb. compression load half-way up the side of a 130-foot masonry tower in Southeastern Massachusetts.
Following the success of this experimental installation, we then developed an ultra-low shrinkage pozzolan-lime grout to be injected through the anchors to adhesively bond the newly tied delamination together. Grout Developers include Professor Norman Weiss of Columbia, University; Irving Slavid, formerly of MCCM Materials Conservation; and John Wathne, PE, of Structures North Consulting Engineers, Inc.
The project was such a success that we founded VoidSpan in 2011 to take what we had invented to the next level. Over the following decade we have made the following inventions and innovations, which are available for sale:
- A complete line of Pozzolan-Lime and Natural Cement based grouts and mortars that are specifically formulated to prevent the white streaking that is so common with lime and cement products. Our natural cement grout is sourced from the Rosendale formation in the Hudson River Valley.
- Vacuum-saturated expanded shale aggregates to extend the grout for large volume fills.
- 90-degree high pressure/low volume pressure washer cleaning jets.
- Water-trickle and low pressure steam pre-dampening devices pressure-controlled grout injection and delivery system.
