Humid Basement Smell - The cracks in the basement wall won't generally weaken the arrangement of your base, but they may cause different problems specifically, water problems.
If it rains outside, particularly in the event that you don't have clean and functional gutters, a lot of the water builds up from the exterior of your basement wall. Unless you get regular basement wall repair to keep these cracks shut, some of the water will enter your basement through these cracks. Even if your basement has a waterproofing membrane on All the exterior walls, a Substantial enough crack may tear or even shred the membrane and then you are in trouble all over again.
Most such cracks can be repaired from the inside in a cost-effective and timely manner that does not disturb the soil or what remains of the waterproof membrane on the exterior. Particularly handy homeowners may even attempt it themselves, but it is not recommended unless you already know just what you're doing.
The best method to perform the basement wall repair is by injecting a growing liquid urethane foam to the crack. When the liquid foam experiences water, it expands dramatically, forcing the foam down and up, inward and outward across the entire length and depth of the crack. It dries and becomes waterproof in moments, sealing the crack absolutely. Since it begins as a liquid of about the same viscosity as water, it is going to go anywhere that the water moves. Since it ends up a foam, it is relatively easy to cut away and, if needed, sand down any of the foam which develops inward however usually, that's not a large matter.
