A cracked or broken foundation wall is a process of building deterioration. There are different types of cracks; foundation specialists could classify them into few groups: vertical and horizontal cracks and staircase cracks.
Vertical cracks might be narrow or wide, but precisely those types of wall cracks allow water penetration and are repaired as needed. It usually does not pose any danger to the building. However, our strong recommendation is to get professional help if the gap is more than 1/2 inches in width.
Horizontal cracks on the opposite usually do not allow as much water as vertical foundation cracks. However, it might indicate high ground pressure from the outside, like water-saturated soil is much heavier and puts extra pressure that could lead to the building's structural problem. Our suggestion - do not wait till the situation worsens, as it might compromise building safety.
