CCS™ Epoxy Injection
ChemCo Systems epoxy crack injection products are specifically designed for machine application (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, high structure temperatures, chemical and radiation resistance, large voids, narrow cracks, plate bonding, wooden (laminated) beams, slab delaminations and structures subject to vibration during cure. For cracks where the backside cannot be sealed (including some floor slabs), we offer a special slump pumping (very fast-set) resin or alternative non-slumping structural paste adhesives. All ChemCo structural injection adhesives exceed ASTM C 881, Type IV specifications for load bearing applications as well as AASHTO M 23.
ChemCo’s large selection of injection seal paste adhesives is 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 pumps. 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). For epoxy injection specifications and concrete crack repair procedures, see the links on the left side of the page.

Standard - High Temperature Ambient Temperature
Features
ASTM C 881, Type IV, (AASHTO M 235). Fast strength, cures under vibration
Primary Uses
When ambient temperatures exceed 90 F. Relatively long potlife. Structural concrete repair. Steel plate bonding. Bolt grouting
Low Viscosity
Features
ASTM C 881, Type IV, (AASHTO M 235). Fast strength, cures under vibration, cold weather suitable. Underwater crack injection capability.
Primary Uses
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.
Slump Pumping
Features
Extremely fast set, low cost
Primary Uses
Repair of slabs and walls where opposite side cannot be sealed. Short potlife, extremely fast cure.
High Temperature
Features
ASTM C 881, Type IV, (AASHTO M 235). Industries’ highest HDT for hot environments.
Primary Uses
Injection resin for structural concrete crack repair and steel plate bonding at high structure temperatures.
Low Exotherm
Features
Minimal heat generation, long mixed useful life, long travel applications, high chemical and radiation resistance. Underwater crack injection capability.
Primary Uses
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.
Low Modulus
Features
Flexible Resin, Low Modulus to Allow for Movement ASTM C881 Type III
Primary Uses
Flexible injection resin for crack repair and sealing.
Underwater and Pile Jacket
Features
ASTM C 881, Type IV, (AASHTO M 235). Best underwater crack injection adhesive.
Primary Uses
Underwater repair of concrete structures in fresh or saltwater. Pier and piling repair using steel or fiberglass jackets.
Capsule and Pressure Pot
Features
Long mixed useful life.
Primary Uses
Low viscosity, extremely long potlife for repairs using pre-mixed capsules or multi-port pressure pot injection systems.
Seal
Features
Workhorse rigid injection seal
Primary Uses
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.
StripSEAL™
Features
Easy cleanup saves labor costs. Sets at 20°F. Won’t crack. Available in two component cartridges. No odor. Popular with precast manufacturers.
Primary Uses
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.
SuperSeal
Features
Fastest cold weather rigid seal in dry conditions.
Primary Uses
Very fast setting seal, sets below 30°F, can inject in 45 minutes, deodorized mercaptan cure.
DucPutty
Features
Can be mixed underwater. Extremely tacky. Kevlar® toughened for mechanical or thermal shock. Won’t move after placement (non-slumping).
Primary Uses
Hand mixable putty for injection seals and underwater spall repair. Useful for leaks and flowing water, sewer pipe repairs, pier and pile repair and underwater concrete patching.
