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).
