Although masonry work is done properly, over the years, the mortar will shrink and allow water to enter a building. Once the water gets between the bricks or block, freezing temperatures will crack the mortar and the bricks. As the freezing and thawing cycle continues, it will push the bricks out of place and cause the building to become unstable. The only way to correct this problem is to have Masonry waterproofing in King of Prussia, PA performed.
