This system consists of a resin cartridge filled with a mixture of resin and hardener, and a separate bolt or anchor that is inserted into the cartridge. When the bolt is rotated, it mixes the resin and hardener, causing a chemical reaction that rapidly cures the resin and creates a strong bond between the anchor and the concrete.
