I am requesting suggestions for an injectable epoxy crack repair kit for our basement wall. The crack is approximately 3mm wide and doesn’t appear to be shearing or moving but it does leak a little during extensive rain. Are there any that are preferred over others? I haven’t seen anything useful at Lowes or the Depot. Thanks

I have a friend that does that work and unless I'm mistaken they inject it under considerable pressure. Doesn't sound like a DIY project realistically...

Google exopy crack repair.
White cap carries one type in double cartridge caulking tubes. The tip mixes the components on the way out. Then there are little injecting tips which are previously separately epoxied on the crack. One goes and covers the chased crack with some of that first epoxy mix so as to seal it.
Some procedures on the web are suited for simple caulking gun pressure to fill said crack. Other materials call for higher pressures.
I had a cracked pool fixed via 'poxy once. They put in a number of those tips and sealed over the cracks and used a seperate pumping station to force the mixed liquid into place.
The viscosity of the type of poxy used is important to keep from running out before it sets.
Yep, that's what I'm looking for. I think with the injection ports and a caulking gun one can get enough pressure to do the job.
abatron. I used their products to repair a fairly large crack in my foundation. It's an involved process cuz you have to insert the "ports" at regular intervals and then patch the rest of the crack so that the liquid you are injecting doesn't ooze out. I used copper tubing for the ports and their thick patching exoxy to patch the crack on the surface. The injection epoxy comes in several different viscosities depending on the thickness of the crack. I used a regular chalk gun and it worked fine, but it was quite a workout. With a thin crack it might be difficult. The amazing thing was how hot the wall became as the epoxy cured. There is a FHB article from about 20 years ago dealing with this process with a lot of good photos, but it shows a contractor doing it with pumps that provided the muscle for the injecting. Ten years later when the same job was needed at my father's house, I got a contractor who did it for about $800 and it was done in a couple of hours.
I did crack injection for years and all we ever used was Sikadur 33 but you need injection equipment to us it.
I see that Sika has a product out called Sikadur Crack Fix that comes in its own injuction tube, see link below.

If this doesn't look like it will work for you Sika has a few more products out, see link below.

Sika is the caddy of the epoxy world and all we ever used for concrete injection.
