Kemko® Injection
The Kemko® Injection Process
The Kemko® Injection Process (KIP) method of injecting cracks down to 0.002 inches wide (2 mils) for their full depth often uses a Kemko® epoxy adhesive without the additional labor time and costs of installing plastic ports. When the injected adhesive cures, it seals the crack entirely and also restores the concrete to its original monolithic integrity. Kemko®’s epoxy crack injection specification provides a
for this process.
Injecting repairable cracks can
- Restore structural and/or design strength to the cracked concrete structure,
- Eliminate concrete spalling initiated by cracking and aggravated by freeze thaw cycling,
- Prevent corrosion of reinforcing steel and pre-stress tendons by encapsulating them against moisture,
- Stop water and fluids leakage through concrete structures (including concrete foundations walls),
- Repair concrete without the unsightly surface marks often caused by standard surface crack repairs (use StripSEAL),
- Restore underwater concrete structures,
- Repair delaminations of topping slabs on floors.
Kemko® epoxy crack injection products are specifically designed for machine application using our specially engineered Model B injection pump. All resins are 2:1 ratios, 100% solids and contain no solvents or fillers. We make the industry’s widest selection of epoxy crack injection resins and surface seals with specialized materials for architectural precast panels, underwater, low and high application temperatures, high structure temperatures, chemical and radiation resistance, large voids, narrow cracks, plate bonding, wooden beams, and structures subject to vibration during cure. For cracks where the backside cannot be sealed, we offer a special slump pumping (very fast-set) resin or alternative non-slumping structural paste adhesive. All Kemko® structural injection adhesives exceed
ASTM C 881, Type IV specifications for load bearing applications as well as AASHTO M 235.
Applications
- Beams, Columns and Precast Panels
- Buildings, Floors, Walls and Parking Decks
- Bridges, Dams, Piers, and Pilings (includes underwater applications)
- Water Treatment Plants, Tunnels and Pipes
- Tank Bottom Grouting
- Highways and Airport Pavements
- Elevated Slabs and Platforms
- Stadiums and concrete framed highrises
- Slab and overlay delamination repair
Kemko® injection seal paste adhesives are used in tandem with the epoxy injection resins. The substrate, surface profile and appearance, application conditions, and project size and complexities are factors to consider when selecting from our wide variety of viscosities, gel times, temperature ranges, and other handling properties. Other Kemko® product categories containing possible surface seal products are the Kemko® Bonders. For large lineal footage applications, we make several seals in a 1:1 ratio available in 5-gallon pails for automatic metering pumps. StripSEAL is a rapid-setting easily removed peelable seal and is the best choice for architecturally sensitive applications to maintain an unblemished appearance (see description below). It is a product very popular with architectural precast manufacturers as it does not affect surface appearance
