Product Description
The Crack-Pac is a two-part, low viscosity crack injection epoxy designed to repair cracks in concrete.The mixed adhesive has the viscosity of a light oil and a low surface tension which allows it to penetrate fine to medium width cracks. Resin is contained in the cartridge and hardener is contained in the nozzle. Once the nozzle is threaded onto the cartridge, the hardener is released into the resin-filled cartridge by turning the knob at the base of the nozzle. The two components are mixed by shaking the cartridge.

I am living in the great Boston area, MA. I bought a new house with a basement about 4-5 feet underground. About a year late the basement had a crack across the foundation wall, about 5 feet high. Only big rain would leak. I saw SIMPSON Crack-pack Kit with pressure injection at Amazon.com. I am not a handyman but decided to give a try. The kit contains a video CD with detail instructions. The steps of paste-over are really straightforward. However, as video said if the crack crosses through wall, it should paste-over cracks inside and outside walls. It was hard to do outside, I had to dig a hole around the crack, eventually went to 3 feet deep.
Before the works I read other reviews, and felt that paste-over leaking could be a big problem. I did very careful about the paste-over, covering every possible hole.
The injection part is a little trick. First is to assemble cartridge and nozzle, then the E-Z-Click tube. Following the video instruction, I used hand to twist off nozzle tip, however, the breakpoint went too low, which caused the E-Z click tube could not firmly attached to the nozzle, and terrible leaking from the junction during injection. So the first set was waste. For second set, I used knife to cut off the nozzle tip at very top and the E-Z click tube was perfectly attached. To ensure no leaking from nozzle-tube junction this time, I tested inject cartridge without attach to the injection ports, but surprising there was no flow. I thought something was wrong and called SIMPSON. The first call did not go through and I left a message. About 30 min late I called again. The SIMPSON tech-supporter was very nice. He explained to me that there is a safe-feature, if the assembled cartridge did not attach to the port, the E-Z click tube is in close position, so would not flow. And he sent me two sets of new free cartridges. The cartridges came next day. I immediately injected to the ports. This time everything went very smoothly. As expected the first epoxy cartridge fast ran out in the two lowest ports because the low part of crack on outside wall was not sealed. The rest went beautifully, no any leaking from the paste-over! A little short for the last two ports however, both of them are above ground.
My lessons:
1. Using knife to cut off nozzle tip not hand twist off.
2. If test assembled cartridge without attached to the ports, there will be no flow. It is normal, a safe feature to prevent leaking.
3. The finished paste-over can last a few days (in my case 2 days), then do the injection, which allows multiple injections if the port has not used.
Recommendations:
It may have an option for the kit including 3 or 4 sets epoxy cartridge, in case of accident or using more such as could not seal the crack on outside wall.
