Step 1Spread the surface sealer onto the base of the port using the trowel. Place the port onto the wall, centered over the crack, cover the base with additional surface sealer to hold it in place. Attach additional ports until a port has been placed at each of the marks (injection ports should be affixed to the wall roughly 8-inches apart). |
Step 2Allow the surface ports to “set” for roughly 10-minutes, and then mix additional epoxy to completely cover the crack opening. Be sure to cover the entire crack. Properly applied surface sealer should be 1/8” thick and extend roughly 1-inch to either side of the crack. Do not push the surface sealer into the crack - just cover the surface. Allow the surface sealer epoxy to cure for 30-60 minutes. Once the epoxy is “fingernail hard”, the injection process can begin. |
Step 3Insert the cartridge nozzle directly into the lowest port. If the crack is horizontal, begin at either side. USING LOW PRESSURE, start injecting foam. Continue injecting slowly until urethane can be seen coming from the port above. Cap the port. Move to the next port, working your way to the top/end of the crack. The foam will completely expand and cure in 3-4 hours. |

Be patient and wear extra gloves!
Had a 5ft vertical foundation crack I wanted to fill before the walls got spray foamed and this was really easy to do. Just need to be patient! Put down some cardboard, use one stick for A and the other for B then another for mixing together and do small amounts at a time because it cures fast. Do NOT mix the mixing sticks in the Part A and B. Once that part is done just set a timer for each port...use low pressure on the caulk gun and it takes a about 5-7 mins to start seeing eutherene come out of the next port. Worked like a charm.

I did end up with twice the amount of expanding foam and about 1/2 the amount of epoxy i ended up needing. I bought some extra epoxy and thought I finished the job, maybe even over did but I had leakage or blow outs under a few of the injection ports. A few tips: wear rubber gloves and get a few extra pairs; i also needed a few plastic butter knives. The epoxy dries very fast. If I had to do it again, I'd start with a small amount and just do the bottoms of the ports for the 1st application. This way you'll get a feel of how much to mix at a time and it will also allow u to take a break and inspect that is good and covered. The bottoms were the trouble area for me. I was fortunate that the injection foam ran out with about 3 ports to go, as it ended up making it the rest of the way and even barely out of the top of the wall due to the expansion. So stop a few holes short. After I finished the injection I waited a few days to remove all the junk with a chisel, I was surprised how easy it was. I had a pretty big pool on the floor at the end, so make sure u have plastic taped down. I also ran tape along each side of the crack before applying the epoxy, thick duct tape. I think having a straight hard edge made removing it easier. Lastly I cleaned up all the leftover junk, retaped the sides and spray painted over the area. It hasn't leaked again yet and we've had some pretty heavy rain. Before the job I'd get about a half gallon after every rain. My walls are 8' and if I didn't have the blow outs, I think I could've easily filled a 12' crack. So basically get some good 2 part epoxy and 1 kit will be enough for 2 cracks; if you really do a good job coating the bottoms.
