WHY REPAIR CRACKS?
Once the underlying cause of foundation cracks has been addressed and necessary measures have been taken to correct the problem, the cracks themselves need to be repaired. There are important reasons for repairing cracks even when they do not indicate significant structural damage. The main objective is to prevent water from entering the basement.
There are several ways in which water can damage basements. The presence of water is necessary for the proper mixing, hardening, and curing of concrete, but continuous movement of it over concrete can lead to its deterioration. Once concrete has begun to deteriorate, the damage can accelerate, ultimately compromising the integrity of the foundation.
The presence of water in a basement can also create a health hazard. The moist environment is conducive to mildew and mold growth. Mold spores are always present in the air but require moisture to grow. The cool, damp basement is an ideal environment for molds to flourish. Once mold becomes established it can affect the air quality, triggering allergies or more severe reactions.
Leakage of water into the basement makes the space less functional. The high humidity can be harmful to stored items such as papers or clothing, and it can make the environment unsatisfactory for working or recreation. From a financial standpoint, a wet basement detracts from the value of a home. Repairing foundation cracks to prevent water seepage is a sound investment in the structural safety, occupant health, and usefulness of a home.
