About Us


VoidSpan Technologies, LLC was created in 2011 by a team of scientists, design professionals and practitioners to offer unique, dependable and practical solutions to the frontier of conservation and preservation challenges.
VoidSpan Pozzolan-Lime products provide high breathability and tenacious bond with low to moderate compressive strength, and our restoration grouts have the lowest water demand and the lowest shrinkage in the industry. When extended with our unique, vacuum saturated expanded shale aggregate, our gravity feed grout creates an ultra-low shrinkage, self-consolidating pozzolan-lime concrete.

Our partnership with Cintec has resulted in the patented VoidSpan Port Anchor, which is the only product on the market that can simultaneously tie and bond separated or voided masonry back together. The Port Anchors are the only system that provide threaded inserts for the attachment of temporary clamping dunnage that allows for 3-foot (one meter) daily grout lifts.

It is our goal to provide “one-stop shopping” for everything you might need for a successful masonry stabilization or conservation project, with installation guidelines, certification, preparation and installation tools, and pass-through sales of other products and systems that complement our own.
We look forward to assisting you.
