Small Finished Basement Before And After - The cracks in your basement wall won't generally weaken the structure of your foundation, but they may cause other problems namely, water issues.
When it rains outside, especially if you don't have functional and clean gutters, lots of the water builds up against the exterior of your cellar wall. Unless you get regular basement wall repair to keep those cracks closed, some of the water will enter your basement through those cracks. Even if your basement has a waterproofing membrane on All the exterior walls, a Substantial enough crack can tear or even shred the membrane and then you're in trouble all over again.
Most such cracks can be repaired from the inside in a timely and cost-effective fashion that doesn't disturb the soil or what remains of the watertight membrane on the exterior.
The perfect way to perform the basement wall repair is by injecting an expanding liquid urethane foam to the fracture. When the liquid encounters water, it expands dramatically, forcing the foam up and down, inward and outward across the entire length and thickness of the fracture. It dries and becomes watertight in moments, sealing the crack perfectly. Since it starts as a liquid of about the same viscosity as water, it will go everywhere that the water goes. Since it ends up a foam, it is relatively easy to cut away and, if necessary, sand down any of those foam that expands inward however usually, that's not a big issue.
