The VoidSpan Port Anchor is a patented stainless steel Cintec sock anchor system that ties separated layers of masonry together while providing a port through which to clean and grout-inject the separations.

Pozzolanic Hydraulic Lime Products are pozzolan-lime formulations with ultra-low shrinkage and surprisingly high adhesion for their moderate strengths.

Pozzolan Lime Products Include:

  • PHLc Gravity Feed Grout
  • PHLc70 Injection Grout
  • PHL and PHLc Mortar Binders
  • PHLc70 Crack Filler
  • PHLc Fine Pointing Mortars
