Pango Bond mastic lets foundation crews bond Pango Wrap to concrete and close out penetrations and terminations. It delivers reliable seals at pipes, edges, and vertical transitions so the barrier stays continuous and inspection-ready on busy pours. The 4-gallon kit supports medium and large slab packages with fewer changeovers. Seal pipe and conduit penetrations fast, stopping moisture and soil-gas bypass paths. Bond membrane to concrete for vertical terminations and secure term bar closures. Conform to rough slab edges and irregular surfaces for continuous contact. Hold detailing through crew movement and material handling before cover placement. Help reduce rework with tenacious adhesion to concrete, metal, and plastics. Use within the Pango system; not a general-purpose adhesive or seam tape; apply to clean, dry, sound concrete and membrane.
