Interior Basement Perimeter Drain Systems - The cracks in your basement wall won't normally weaken the structure of your foundation, but they may cause other problems namely, water problems.
If it rains out, especially in the event that you don't have clean and functional gutters, lots of the water builds up against the exterior of your cellar wall. If you don't get regular basement wall repair to keep these cracks closed, some of the water will enter your basement through these cracks. Even if your basement has a waterproofing membrane on all of the exterior walls, a Substantial enough crack can tear or perhaps shred the membrane and then you are in trouble all over again.
Most such cracks can be fixed from the inside in a timely and cost-effective fashion that does not disturb the soil or what remains of the waterproof membrane on the exterior.
The perfect way to perform the basement wall repair is by injecting a growing liquid urethane foam to the fracture. When the liquid encounters water, it expands dramatically, forcing the foam down and up, inward and outward across the entire length and thickness of the fracture. It dries and becomes more waterproof in moments, sealing the crack absolutely. Since it starts as a liquid of about precisely the same viscosity as water, it will go everywhere that the water goes. Since it ends up a foam, it's relatively easy to cut away and, if necessary, sand down any of those foam which expands inward though usually, that is not a large matter.
