How To Repair Cracked Concrete With Epoxy

Eliminate wet, damp basements by repairing leaking cracks in concrete with an epoxy injection kit.


  • Step 1: Plug each port as you fill them, continuing until you've filled them all.
  • Step 2: Allow the epoxy to dry, about 24 to 48 hours. Remove the ports with a hammer and sand any imperfections as needed.
  • FACT: Did you know? The first concrete domed sports complex, the Assembly Hall, was constructed at The University of Illinois, at Urbana-Champaign, in 1967.
  • Step 3: Mix the epoxy in the injection cartridge. Starting at the bottom port, inject the epoxy into each port until epoxy starts to come out of the port above it.
  • Step 4: Cover the entire crack, as well as the base of each port, with a generous coating of the surface epoxy and allow it to dry.
  • Step 5: Mix the epoxy in a bowl and stir thoroughly.
  • Step 6: Place a small amount of epoxy on the base of each surface port and attach it directly over the crack.
  • TIP: Ports are placed an inch apart for each inch of surface thickness.
  • Step 7: Clean the area around and along the crack. Use a stiff brush to remove any loose dirt.
