Foundation Repair questions, answered by experts

Water damage in your home’s foundation is gradual, often beginning with small cracks that let water seep in. Over time, this weakens the foundation, which then allows in more water, causing significant structural damage. This process can take months or years to destroy your foundation, and the repairs can be very costly. Have your foundation inspected regularly to prevent significant damage.

It’s usually not a big deal if your foundation sinks between 2 and 3 inches into the ground after construction, provided the settlement occurs evenly. This is usually indicative of normal settlement that occurs as the soil under your home adapts to the weight of the structure. If the home sinks more into the ground or the settlement occurs unevenly, leaving portions of your home to sink further down than others, then call a foundation repair specialist to address the issue and avoid additional damage.

Cracks, shifting, or uneven floors indicate potential foundation issues.

Visible cracks, scaling, flaking, and uneven surfaces indicate a bad concrete job. Additional signs vary depending on the project. You may notice poor drainage or even exposed rebar. Quality issues result from using the wrong concrete, rushing the work, or inexperienced workers completing the job.

Yes, all basement floors crack in response to the natural settlement of the soil around them and from concrete shrinkage as it cures, and you’ll see hairline cracks as a result. However, you should keep an eye on your basement floor to see if cracks continue to lengthen or widen or show signs of water intrusion. In any of these cases, the problem is likely not settling or shrinkage, and a professional repair is necessary.
