i just bought a two year old home that has 2-3 vertical cracks in the poured basement walls that with heavy rain will weep moisture. two of them extend down from windows (small basement type, openings formed into the pour)that are approx. just less than 1/4 inch at the widest. i have heard of injectable epoxies that can be done from inside, i plan to stud and insulate the walls, and wonder if anyone has experience with this type of repair. i am not necessarily looking for quick or easy, but want a proper long term fix. i am a part-time remodeling contractor and have not had to deal with this yet… thanks!!

Call a formed wall contractor. They should be able to give you the name of a repair contractor. It's not a DIY project very stinky stuff and specialized tools.
good luck
*Kevin, FWIW at recent homeshow vendor gave me quote of $425 to do an 8'H crack that is not as wide as yours. Nozzle drill ports and expanding foam sealant applied under pressure used along crackline, 5yr. warranty. Still searching options. If not mistaken, I think there is(was) an ad in FHB for same type product that DIYer can do. Good luck.
*Kevin: The product/system Buffalo refers to is made by a company called Prime flex, website ie primeresins.com. I just had it done at my father's house for $460 for one crack. It's a polyurethane product which is injected with water, which acts as a catalyst. It cures to a flexible but very tough rubber-like consistency, like a gasket. This supposedly allows it to withstand any movement of the walls and not crack like hydraulic cement. Done in two hours, minimal mess. Money well spent. I'm not sure if they sell to the public. Requires special equipment to pump the material into the crack.
*Concrete Construction magazine often has ads for 2-part epoxy injection system for small jobs (similar to caulking tubes). http://www.worldofconcrete.com may be of some help. Randy
*kevin,If you're o.k. with slow, heavy and potentially expensive I'd say better drainage is your first step. Dig and drain. Use proper drainage on the outside to keep the water away from your cracks to begin with.BCK
*Try to figure out how the crack got there in the first place.....wall could not have been braced properly during backfill.......the ground against the house should have an easily seen slope AWAY from the house, you could be trapping water in a pocket alongside the exterior basement wall....... The footer drains may be disabled from shoddiness of all sorts. No sense fixing just the cracks untill you know how they got there.
