This homeowner in North Tonawanda, NY, noticed their walls bowing outwards, which caused several cracks along their walls. Our crew came in and installed both i-beams and CarbonArmor to combat the bowing walls. What's the difference? CarbonArmor is actually just as strong as an I-Beam, but due to the relative spacing and placement of an I-Beam, CarbonArmor may be suggested instead.
