We found a vertical crack in our full basement wall. The top is about .5cm wide and narrows to a few mils at the bottom. Some water has leaked in. There is a little mold, and the bottom wall board has rotted. Can this be repaired with those urethane injection methods?
It sounds like you are dealing with a finished basement and are going to cover up the area again when repaired. Your foundation is major building structure and you should not take any chances on the repairs. It must be sound and watertight before you re finish.
Post your requirements in the projects section and I am sure you will get many qualified people to respond.
Yes you can repair the crack with an injection method. Another method that is very effective is called a Dry-Well Repair, in which a small section of membrane is applied. However be very careful with companies that offer a much lower rate, and always get a couple of prices.
Many crack injections have been known to fail in just a few short years, so ask about a warranty.
