If you have vertical or horizontal cracks in concrete your best method to seal them would be to use an epoxy crack injection kit. Sealing the cracks in concrete will help prevent water from soaking in and causing harm to the rebar.
The first step when rehabilitating concrete using the epoxy crack injection method is to use an epoxy paste to close the outside of the crack. While doing this you will also install injection ports approximately every 8″ apart. Sealing the outside with a paste will help prevent the lower viscosity epoxy from spilling out when you are injecting into the ports.
Once the epoxy paste hardens fully you will use a caulk gun to dispense low viscosity epoxy into the concrete starting at the lowest point. The low viscosity will allow the epoxy to penetrate deep into the concrete bonding everything back together.
After letting all of the epoxy cure you can chip off the ports and grind any excess epoxy flush with the concrete.
