Types of Cracks
Concrete does two things; it gets hard, and it cracks. When looking at a crack in a house’s foundation wall, the type of crack can often indicate what is causing the crack to occur. Vertical or stair step cracks indicate settlement of part of the wall or uneven weight distribution from above. The hairline varieties of such cracks are common and usually nothing to worry about. Horizontal cracks, on the other hand can be worrisome. A horizontal crack in the middle of a wall indicates there is pressure from the exterior pushing in on a wall. If it is allowed to push too far, the wall can buckle and fail. Early detection is key and the right fix can help a home owner avoid further damage and high repair bills.
