VoidSpan PHLc70 Injection Grout is a breathable, ultra-low shrinkage, flowable, self-consolidating fine grout for use in injection and gravity filling of cracks and defects in older masonry elements as well as for structural bonding of delaminated mass masonry leaves. Based on a pozzolanic hydraulic lime “PHLc” as per ASTM C1707, it is a low-to-moderate strength adhesive, filler and fine mortar replacement material. Uses Include:

  • Gravity feeding and fine injection filling of cracks as narrow as 1.5 mm (1/16”) in width.
  • Low pressure bulk injection of cracks and voids in mass masonry construction using cavity-grouting VoidSpan Port Anchors.
