Polygem LCR Concrete Crack Repair Epoxy Injection Bundle, 10 oz 2-Part Cartridge with 7 White Surface Ports, for Foundation & Basement Cracks

Repair a cracked concrete or foundation wall with the Polygem LCR Concrete Crack Repair Epoxy Injection Bundle — a lower-cost, targeted option that pairs one 10 oz cartridge of two-part LCR injection epoxy with 7 clear surface injection ports. Ideal for a single crack or smaller repair; for larger or multiple cracks, choose a complete kit that includes paste and additional cartridges. Bundle includes: one 10 oz dual-chamber cartridge of LCR injection epoxy (Part A & B, low-viscosity, 100% solids) with mixing rod and nozzle, plus 7 clear surface injection ports. A standard caulk gun is needed to dispense (sold separately). Important — paste required: To complete the repair on a vertical wall, you'll also need Polygem LCR Repair Paste (sold separately). The two-part paste mounts the injection ports and seals the crack surface; once it has cured, inject the LCR epoxy through the ports with a caulk gun. This bundle does not include the paste. How it works: The low-viscosity epoxy penetrates deep into the crack and bonds to damp or dry concrete — the crack should be moist or dry, not actively running with water. It cures to an amber/tan color and is sandable and paintable. Initial set 4–6 hours; full cure in 24 hours. Also bonds wood, fiberglass, and metal.

• Targeted Single-Crack Repair: Pairs one 10 oz cartridge of Polygem LCR 2-part injection epoxy with 7 clear surface ports — a lower-cost option for repairing an individual concrete or foundation crack rather than a full wall.
• Permanent Structural Repair: 100% solids, moisture-insensitive epoxy restores structural strength to cracked concrete and also bonds wood, fiberglass, and metal. Penetrates deep and cures hard for a lasting repair.
• What's Included — Cartridge + 7 Ports: One 10 oz dual-chamber LCR epoxy cartridge with mixing rod and nozzle, plus 7 clear surface injection ports.
• Requires LCR Repair Paste on Vertical Wall Crack (Sold Separately): Use Polygem LCR Repair Paste to mount the ports and seal the crack surface, then inject the epoxy only after the paste has cured. This bundle does not include the paste.
• Seals Damp or Dry Cracks: Bonds to damp or dry concrete (not actively running cracks). Cures to an amber/tan color; sandable and paintable once fully cured. Initial set 4–6 hours; full cure in 24 hours.
• Only Tool Needed — a Standard Caulk Gun: Uses any standard 10 oz caulk gun (sold separately) to dispense the resin; no special equipment, drilling, or crack-chasing required.
