LIME-BASED MORTARS & GROUTS

VoidSpan Technologies LLC masonry restoration system combines grout injection port anchors with pozzolanic hydraulic lime grouts to stabilize and rebond historic masonry where voiding, delamination, and loss of cohesion have occurred. Sock-based anchors permit inspection, cleaning, pre-wetting, and controlled injection through a single installation, forming a unified composite repair. PHL formulations balance compatibility with traditional materials and the practical demands of field application, offering ultra-low shrinkage, vapor permeability, and moderated strength appropriate to historic fabric. Systems are used for wythe reconnection, crack injection, void consolidation, and bonding of displaced masonry, with supporting equipment and installation methods enabling precise execution across complex preservation and rehabilitation work.
