Injection epoxies

Tested to the latest ASTM standards, a new CI family of crack injection epoxies offers viscosity range and accelerated cure times, and can be installed at temperatures between 40°F and 110°F to meet real-world concrete repair demands. The company has concurrently upgraded its suite of dispensing tools and injection systems to help make applications fast, easy, and clean for contractors on the move. From hairline cracks to wider concrete fractures, crack injection repair products are designed for both cartridge and pump applications to suit a variety of jobs. Products have been formulated for retrofit or repair work in light structural, tilt-up, water treatment, bridge and marine, plus commercial construction and restoration projects.

“Although predominantly used for retrofit and repair work, this upgraded collection of concrete injection epoxy products and accessories can be used in new construction as well,” says Simpson Strong-Tie Director of Concrete Construction Products Ryan Kaelin. “The availability of products in cartridges suits small- to medium-sized jobs where it’s not efficient to set up pneumatic pumps. All of our crack injection solutions are backed by training, jobsite support, and nationwide availability.”

The line of CI structural injection epoxy products, each with viscosity ratings at 72°F, includes: SLV super-low-viscosity (150 cps); LV low-viscosity (350 cps); LV FS fast-setting low-viscosity (600 cps); LPL long-pot-life (2000 cps); and, GV structural injection epoxy gel.
