Thin Insulation For Basement Floor - The cracks in the basement wall won't generally weaken the structure of your foundation, but they may cause different problems specifically, water issues.
If it rains outside, particularly in the event that you don't have clean and functional gutters, lots of that water builds up against the exterior of your cellar wall. If you don't get routine basement wall repair to keep these cracks shut, some of that water will get into your basement through these cracks. Even if your basement has a waterproofing membrane on all of the exterior walls, a significant enough crack can 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 timely and cost-effective fashion that does not disturb the soil or that which remains of the watertight membrane on the exterior.
The perfect method to execute the basement wall repair is by injecting an expanding liquid urethane foam to the fracture. When the liquid foam experiences water, then it expands dramatically, forcing the foam up and down, inward and outward along the whole length and depth of the fracture. It dries and becomes more watertight in minutes, sealing the crack absolutely. Since it starts as a liquid of roughly the same viscosity as water, then it is going to go everywhere that the water goes. Since it ends up a foam, it is relatively easy to cut away and, if needed, sand down any of the foam that expands inward though usually, that is not a large issue.
