Product Overview

Simpson Strong-Tie offers reliable, easy-to-dispense products for a variety of restoration applications, including structural restoration, pick-proof sealing and water-intrusion prevention. The Crack-Pac two-part, high solids, low-viscosity crack injection epoxy is designed to repair cracks in concrete. The mixed adhesive has the viscosity of light oil and a low surface tension that enables 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.

  • Dispenses with a standard caulking tool, no dedicated dispensing tool needed
  • Low viscosity
  • Clean and easy mixing; no additional tools required
  • Chemically bonds with the concrete to restore strength
  • Resistant to oils, salts and mild chemicals
  • Non-shrink

how long of a crack does this cover

Have seepage where inside foundation wall and floor meet. Will this product seal seperation and further seepage from outside?

Asked by: GolfDoc
No: normally the footing and the wall are poured separately and sealed with a fiber liner. This product will not work: ask a professional about a proper solution.

Rated 5 out of 5 by from Great product Works really, really well. Saved me from having to dig around the basement and reseal from the outside. Just a note of caution - make sure that you shake/mix the sealant really well before injecting it. I didn't on the last tube I used and you could tell that it did not set up as well as the rest. My fault but thought I would share.

Rated 5 out of 5 by from Epoxy flows into crack and fills voids, seen and unseen! As advertised, product works. I bought extra epoxy pre-mixing in a tube for sealing the backside of the 8' crack in a poured foundation wall. Widest point in crack was .25 inch down to barely visible hairline. Without excavating the external wall and covering the crack with the thicker epoxy, a majority of the thin epoxy crack filler would have been wasted. The thin crack filling epoxy flowed well and amazing filled the crack up the wall to the next injection point. I was unsure if the crack was one continous crack or in series...the epoxy flowed into and even seeped out slightl to hairline cracks I had not noticed. My biggest complaint was the cure time took 24 hours in 60 degree weather (temps steady for weeks prior).

Rated 4 out of 5 by from Crack-Pac Injection Kit-- it works!!!! The only reason I didn't give this product 5 stars is because the instructions and video could be better. The instructions really need to emphasize the need to put liberal amounts of the paste-over epoxy around the injection ports. I didn't and as a result I had lots of the injection epoxy coming out from under the ports. Nevertheless, enough of the injection epoxy stayed in the vertical crack I had running down the length of my basement wall and it made an excellent seal. This product works!!!! It's messy and it stinks (like a perm on steroids) but it works!

Rated 4 out of 5 by from Worked well, not designed for corners I purchased this product to repair a crack in my foundation that happened to be in a corner where one solide of my foundation meets another. I was able to use the product successfully. However, the injection ports are almost the diameter of a half dollar and thus won't fit in a corner. I had to trim the sides off all of them to get anywhere close enough to epoxy into the corner to allow for a seal. This did work and I have had no further leaks since the repair. This project wasn't quite as straight forward as I thought it would be due to the location of the crack and the modifications I had to make to the ports

Rated 5 out of 5 by from This product definately works you do need ventilation. it takes awhile between products to dry sufficiently. easy instructions and easy to use. sealed our cracks completely

Rated 4 out of 5 by from Messy, stinky This stuff STINKS! like, Whoa! And the epoxy was really messy, and not super easy to apply, however this foundation crack is horizontal, towards to bottom of the foundation wall behind some frame work so it was... awkward. I, apparently, made the mistake of not COMPLETELY sealing around the portals, so when I started slowly injecting the gel, it started oozing out of the unsealed holes as minuscule as it may have been. I had to quickly grab a sealant I had laying around to try to patch around the portals before injecting more gel. So word of advice, make sure the area around the portals are COMPLETELY sealed! Maybe because of these seemly awkward accessibility to the crack, I don't feel 100% confident that it totally sealed the crack behind the patchwork. If I had to do this project again I'd do it differently, live and learn;) I rate this 4 regardless because it makes sense, and I feel that in different circumstances it would have been much easier to apply etc. Recommended for a straight-foward, easily accessible crack
