Humid Basement Open Windows - The cracks in the basement wall will not normally weaken the structure of your foundation, but they will cause other problems namely, water issues.
If it rains outside, particularly in the event that you don't have functional and clean gutters, lots of that water builds up against the outside of your cellar wall. Unless you get routine basement wall repair to keep those cracks closed, some of that water will get into your basement through those cracks. Even if your basement has a leaky valve on all of the outside walls, a significant enough crack may tear or even shred the membrane and then you are in trouble all over again.
Most such cracks can be fixed from the inside in a cost-effective and timely manner that doesn't disturb the soil or what remains of the waterproof membrane on the outside.
The best method to execute the basement wall repair is by injecting a growing liquid urethane foam into the crack. When the liquid encounters water, it expands dramatically, forcing the foam up and down, inward and outward along the whole length and thickness of the crack. It dries and becomes waterproof in minutes, sealing the crack perfectly. Since it begins as a liquid of roughly precisely the same viscosity as water, it will go everywhere that the water moves. Since it ends up a foam, it is relatively simple to cut away and, if needed, sand down any of those foam that develops inward though usually, that is not a large issue.
