ETI injection epoxies are specially designed formulations for the injection of cracks in concrete. ETI epoxies are two-component, high-solids formulations. They are available in side-by-side cartridges and are dispensed through a static mixing nozzle using a standard dispensing tool. ETI is available in three viscosities: ETI-LV (low viscosity), ETI-GV (gel viscosity) and ETI-SLV (superlow viscosity) to handle a wide range of crack widths. Properly installed, they provide a repair that is both waterproof and high strength (structural).
