Masonry concrete wall cracks

Not every concrete wall needs to be repaired if it is cracked or damaged in any way and in any area. Some small damage can be left alone without anything bad happening. However, once a concrete wall starts to crack (just about all do) the crack it will not lessen and diminish over time. On the contrary, it may grow. If the crack is causing damage to the structure, major repairs are necessary that can be very expensive.

There are several reasons why a wall may crack, some are a big deal others are not. The root of a crack is likely due to problems that occurred before the concrete wall is even poured. Problems with soil under the footing can easily be the root cause of problems with concrete walls that can take years or decades to be visible. Footings poured on mud, debris that deteriorates or on unstable soil are likely to fail. Repairs to footings and the soil under them are very difficult and expensive as it is usually necessary to temporarily support the structure in order to allow the soil under the footing to be removed and replaced.

Cracks in foundation walls that are horizontal are very troublesome as they usually indicate the foundation wall is being pushed in. Many times this is due to surface water saturating the soil. When the saturated soil freezes it expands pushing the foundation wall in. Pushed in foundation walls are very expensive to fix and the usual cure is to temporarily support the home, remove the damaged wall and replace it. Sometimes installation of vertical supports or pilasters can stop further movement of the foundation wall effectively. In any and all cases repairs to foundation walls must be performed under the supervision of a Licensed Design Professional in order to avoid creating unsafe conditions or making the problem worse.
