ChemCo Systems epoxy crack injection products are specifically designed for automatic metering pumping application such as our Model B epoxy injection pump (with 2:1 ratios), are all 100% solids and contain no solvents or fillers. We make and stock the industry’s widest selection of concrete crack repair adhesives with specialized materials for architectural precast panels, underwater, low and high application temperatures, underwater concrete crack repair (including swimming pool and salt and freshwater pier and piling repairs), water storage tanks and structures, dams, high structure temperatures, chemical and radiation resistance, large voids, narrow cracks, plate bonding, wooden (laminated) beams, slab delaminations and concrete structures subject to vibration during cure. For cracks where the backside cannot be sealed prior to injection (including some floor slabs), we offer a special slump pumping (very fast-set) resin or alternative non-slumping structural paste adhesives. All ChemCo structural epoxy injection adhesives exceed ASTM C 881, Type IV specifications for load bearing applications as well as AASHTO M 235.
ChemCo’s large selection of injection seal paste adhesives are used in tandem with the epoxy crack 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 product categories containing pastes or gels usable as surface seal products are in the CCS Bonders catagory. For large lineal footage applications, we make several seals in a 1:1 ratio available in 5-gallon pails for use with automatic metering paste (gel) pumps, including ChemCo’s Model C paste pump. StripSEAL™ is a rapid-setting peelable surface seal and is the best choice for architecturally sensitive applications to maintain an unblemished appearance (see description below).

Workhorse injection resin for the repair of structural cracks and delaminations in concrete. Steel plate bonding. Vertical bolt grouting.
ASTM C 881, Type IV, (AASHTO M 235). Fast strength, cures under vibration.
Use when ambient temperatures exceed 90 F. Relatively long pot-life. Structural concrete repair. Steel plate bonding. Bolt grouting.
ASTM C 881, Type IV, (AASHTO M 235). Fast strength, cures under vibration, cold weather suitable. Underwater crack injection capability.
Injection resin for the repair of cracks and delaminations in concrete. Low viscosity for use with fine cracks down to 5 mils and at low application temperatures to 35F.
Extremely fast set, low cost.
Repair of slabs and walls where opposite side cannot be sealed. Short potlife, extremely fast cure.
ASTM C 881, Type IV, (AASHTO M 235). Highest HDT (heat deflection temperature) epoxy injection adhesive for hot environments.
Injection resin for structural concrete crack repair and steel plate bonding at high structure temperatures.
Minimal heat generation, long mixed useful life, long travel applications, high chemical and radiation resistance. Underwater crack injection capability.
Long potlife, low exotherm on cure for repair of honeycombed concrete, large voids and delaminations. Excellent for many void-grouting applications under tanks and equipment. Can be placed in bulk hand mixes due to low exotherm.
Flexible (low modulus) Epoxy Resin to Allow for Movement. ASTM C881 Type III for hard concrete to flexible substrates.
Flexible injection resin for crack repair and sealing.
ASTM C 881, Type IV, (AASHTO M 235). Best underwater crack injection adhesive. Performance not matched by any other product available in the U.S.
Underwater repair of concrete structures in fresh or saltwater. Pier and piling repair using steel or fiberglass jackets.
Long mixed useful life.
Low viscosity, extremely long potlife for repairs using pre-mixed capsules or multi-port pressure pot injection systems.
Workhorse rigid injection seal
Fast set crack seal, excellent grindability, low odor. Sets up in about an hour for crack injection. Easy mix 1:1 ratio. For overnight set, use Bonder Paste, Long Work Life.
Easy cleanup saves labor costs. Sets at 20°F. Won’t crack. Available in two component cartridges. No odor. Popular with architectural precast manufacturers.
Fast setting, strippable seal for injection repair in 30-40 minutes. No grinding required. Flexible for use on moving cracks. Peels off like a tape. Often used on architectural precast surfaces.
Fastest cold weather rigid seal in dry conditions.
Very fast setting seal, sets below 30°F, can inject in 45 minutes, deodorized mercaptan cure.
Can be mixed underwater. Extremely tacky. Kevlar® toughened for mechanical or thermal shock. Won’t move after placement (non-slumping).
Hand mixable putty for injection seals and underwater spall repair. Useful for active leaks and flowing water, sewer pipe repairs, pier and pile repair and underwater concrete patching.
