Welcome to VoidSpan

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.

VoidSpan Technologies, LLC is a manufacturer and supplier of a unique line of Historic Masonry Conservation and Restoration Products. These include:

VOIDSPAN PORT ANCHORS which simultaneously tie and bond voided masonry together so that it acts as a unified composite system.

VOIDSPAN PHL AND PHLc MORTARS AND BINDERS. Our binders can be mixed with your choice of sand to produce low to moderate strength hydraulically setting lime based mortars and our Fine Pointing Mortar can be used to fill moderate sized cracks and repoint tight butter joints.  

VOIDSPAN PHLc GROUTS, which include a pourable gravity feed formulation and a fine (PHLc70) injectable one.

VOIDSPAN EXTEND BRAND AGGREGATE is a vacuum saturated expanded shale that can be mixed with our gravity feed grout to produce an economical, flowable, lime based concrete for filling large cavities without segregation.

VOIDSPAN PHLc70 CRACK FILLER for filling fine cracks in historic stonework.

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 offer the following additional products, equipment and services:

We look forward to assisting you!
