How to repair a leaking concrete wall.
Seal the wall crack when properly done sealing leaking wall cracks is a permanent effective solution.
Project instructions step 1.
Mix the concrete with water until it reaches the consistency of thick mud.
Injecting a typical wall crack with an epoxy or urethane resin is done under pressure pushing the material from the inside all the way to the outside.
If you have very small cracks in your concrete wall use a sealant or a brush on compound that you apply to the wall like paint.
Allow the concrete to dry for 24 hours.
The trick to this is to find a solution that will not peel off the wall or fail as the wall naturally expands and shrinks over time.

The injection process fills the crack from top to bottom from inside to outside.
Squarely cut or undercut the edges of the crack.
Waterproofing materials that go on like paint fill the pores in the concrete or masonry walls and prevent water from leaking in.
Then clean off any white powdery efflorescence with masonry cleaner.
