VoidSpan Grouts are flowable, ultra-low shrinkage materials that can be used in both injection and gravity-fed applications and are compatible with a variety of historic masonry substrates and types of assemblies. Our grouts have the lowest water demand and curing shrinkage in the industry for a non-expanding grout and our inclusion of a pozzolan all but eliminates the possibility of lime bleed.

Restoration Mortars

VoidSpan PHLc Fine Pointing Mortar is intended for use in filling fine “butter joints” of ¼” or less width and has a fine rounded particle sand aggregate that makes it easily workable and compactable in such narrow joints. These mortars are available in a light gray and buff white color. Additional pigments can be added by the installer if desired.

VoidSpan “Extend” Vacuum Saturated Expanded Shale Aggregate has a similar specific gravity to our PHLc Grouts and can make any of our grouts into a flowable, self-consolidating “Lime Concrete” for pouring into large gravity feed grout, simply by blending the aggregate with the pre-mixed grout.
