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

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.
