Polygem Concrete Crack Repair Epoxy Injection Kit, 11 Piece, Gray/Tan

Repair up to 8 feet of cracked concrete like a pro with the Polygem LCR Concrete Foundation Crack Repair Kit — a complete structural injection system for basements, foundations, slabs, driveways, sidewalks, pools, and garages. Sized for a full wall crack or several smaller cracks (an average 1/16" wide, 8-foot crack). Kit includes: two 10 oz cartridges of LCR injection resin (Part A & B, low-viscosity, 100% solids epoxy), two pints of LCR crack sealer paste (Part A & B), 7 surface injection ports, mixing rods and nozzles, and step-by-step instructions. All you add is a standard caulk gun. How it works: Apply the two-part repair paste to mount the ports and seal the crack surface. Once cured, inject the low-viscosity LCR resin through the ports with a caulk gun. It penetrates cracks as fine as 0.005" and bonds to damp or dry concrete — the crack should be moist or dry, not actively running with water. After full cure, the repair seals the crack from the inside out, restoring strength and preventing water intrusion. The cured epoxy is high-strength, moisture-insensitive, sandable, and paintable, and cures to an amber/tan color. Full cure in 24 hours. Zero VOCs and solvents.
