Foundation Cracks and How to Fix Them

Problems connected to building and construction usually appear after the healing of the concrete in the form of cracks. Foundation cracks are annoying and sometimes quite terrifying to the building constructor or homeowner. It is important that both be conversant with the essence of these cracks to know how to prevent, mitigate, and understand the severity.

The Essence of Foundation Cracks

It is typical that the drying of concrete is an essential aspect of the stability of construction work, and it should be controlled to prevent unnecessary sore results. Sometimes, the concrete dries up unevenly, and as it shrinks, it forms cracks that range in severity. It is essential to note the cracks that require ornamental patching and the lethal ones that require serious attention. The following are the foundation crack indicators you should check.

  • Hairline-Sized Cracks usually appear in mortars between the blocks of concrete and do not pose a serious problem.
  • The L-Shape Section Cracks are often formed where the foundation is constructed on a hillside and uneven shrinking occurs. The major issue caused by these cracks is the wetting of the basement and should be patched up to keep the floor and wall dry.
  • Cracks in the steps of a stair, especially at the masonry joints, are usually bigger, more than a quarter of an inch, and may cause the wall to bulge. The cracks pose a far-reaching structural problem and require immediate repair. Moisture problems and the plugging of a gutter are the usual suspects for these foundation cracks.
  • The worst foundation cracks are called Horizontal Cracks and signal the need for reconstruction of the entire foundation. Horizontal cracks can bring down the whole building if constructed upon such a foundation. The freezing and later expansion of frozen water-laden soil pushes against the foundation and breaks it in various places. Another common cause is building on ground that shrinks and expands due to changes in water content.

Ways and Costs of Repairing a Foundation

  • The use of steel braces or a mesh of carbon fiber with epoxy glue strapping to bolt the cracks may cost approximately $600 and $400 respectively.
  • The reconstruction of the entire foundation may cost as much as $40,000, which is quite a sum, especially due to the costs of previous construction.

Professional Help

The services of a professional will assist you in the assessment of the severity of the construction problem and the remedial steps required. However, a structural engineer will charge you approximately $600 for inspection services and $2,000 for a fully-fledged engineering solution.

Professional help is not only advisable, but also important in giving you an accurate solution to the actual problem. Foundation issues need close attention regardless of the level of seriousness since the construction of a living space should be as perfect as possible.


Honeycombing describes the rough and pitted surfaces on concrete that are a result of incomplete filling. This can be a sign of more serious damage within the concrete wall and act similarly as a crack would by allowing water to sneak in.

Water Stains

Water stains appearing at the top of your basement walls can also be a sign unwanted water is making its way into your basement. This can be prevented by professionally waterproofing the walls of the basement. However, this can also be caused by roof runoff or another source, so make sure you identify the problem before trying to solve it.
