Tips on Basement Foundation Cracks

The Indianapolis foundation walls and floor of your Indianapolis basement are built to support your house and to keep out the moisture that surrounds them. Their purpose is to keep your home a dry and create a stable structure for you and your family.

When Indianapolis foundation walls crack, it can cause moisture or harmful gases from the ground to seep into your basement, decreasing the air quality, causing mold growth and damaging personal property.

There is no viable quick fix when it comes to Indianapolis basement Indianapolis foundation crack repair. There are different correction methods and knowledge needed to fix them correctly. Let’s take a look at the list below for some tips and a little more knowledge about Indianapolis foundation cracks.

1. There are three reasons for cracks in your Indianapolis basement foundation:

  • Shrinkage: Shrinkage is caused by the poured concrete, walls or floor, drying too fast. The quick drying time causes the concrete to shrink, and hairline cracks are the result. Shrinkage is noticeable not long after the construction of the house.
  • Settling: Settling causes cracks in the Indianapolis basement Indianapolis foundation when the ground below the Indianapolis foundation continues to compress under the weight of the poured concrete. The cracks that happen are a result of settling and directly related to the amount of ground compression. If the ground under the Indianapolis basement Indianapolis foundation only compresses for a short time, the cracks are generally minor. However, if the ground continues to settle for a more extended period, the cracks can become more numerous and troublesome.
  • Movement: The most common cause of Indianapolis basement Indianapolis foundation cracks is movement. Movement and shifting in the ground under the Indianapolis foundation can cause Indianapolis foundation cracks. As with settling, if the movement continues, the cracks will get worse.

Cracks in Indianapolis foundation walls and floors happen for the same reasons but are not the same when it comes to fixing them.

  • Cracks in the Indianapolis basement Indianapolis foundation floor can be more challenging to fix, especially if you are noticing leaking or wetness. Typically, the floor cracks will only leak when there is a significant amount of water leaking underneath your Indianapolis basement floor.
  • If you are noticing leaking on your Indianapolis foundation floor, it would be a good idea to check your sump pump. Often, when you see water coming through the cracks on the Indianapolis basement Indianapolis foundation floor, the sump pump has stopped working as it should. If your sump pump is working, then an underground drainage system could solve your floor leakage issues.
  • When water leaks are noted, Indianapolis basement Indianapolis foundation crack repair becomes very difficult. Wet concrete will not allow waterproofing products to adhere well or permanently. Also, for the best seal, the product would have to be applied to the top and underside of the floor which would be very difficult at best.

3. Basement Indianapolis foundation cracks can negatively affect the air quality in your basement.

  • Though water leakage, through Indianapolis foundation cracks, can be a big hassle, cracks in Indianapolis basement Indianapolis foundation walls and floors could be an entry for other potentially dangerous gases, such as Radon, Methane, and even pesticides.
  • When the cracks give these gases a possible entry into your basement, the air quality in your Indianapolis basement could become a problem for you and your family.

4. Mold

  • Basement Indianapolis foundation walls that have water leaks can potentially cause a mold infestation in your Indianapolis basement due to the excessive moisture that can soak into the concrete. Mold can slowly spread throughout other areas of your home.
  • At a glance, mold on your walls is unpleasant to look at and could cause a nasty smell as well. However, the potential health risks and structural risks to your family and home could be a lot more dangerous. Mold not only destroys the material it colonizes on, but it can also adversely change the air quality that in turn could cause illness.

5. Different types of Indianapolis basement foundations require different types of repair for optimal results.

  • Poured concrete: Poured concrete walls are stable and formed as a solid block of concrete. If you need to repair cracks in this type of structure, an expanding urethane based sealant can be injected into the cracks to seal them.
  • Block, Brick or Stone: Walls made out of these materials are made up of multiple parts patched together with cement or mortar. Repairing cracks in these types of structures is best done from the outside rather than the inside of the basement. A flexible elastomeric membrane is a preferred material for this type of Indianapolis basement Indianapolis foundation crack repair.

6. Epoxy for Indianapolis basement Indianapolis foundation crack repair

  • Epoxy is a substance that can be used to fix cracks in poured concrete Indianapolis basement Indianapolis foundation structures. Using epoxy for crack repair may not stop the wall from cracking or leaking again in the future if there is a continued problem with the ground pressure pushing against the walls. However, this could be a quick-fix option until further investigation is done on your foundation.

7. Repairing previously repaired cracks

  • It is vital that previously repaired cracks are repaired correctly as they are different than a new crack and require additional preparation and knowledge when selecting a method of repair that will be effective.
  • Taking the time to remove as much of the previous repair medium as possible, and injecting the crack with urethane on the inside of the structure, is a suitable method.
  • A previously repaired crack can also be corrected from the outside using either the elastomeric membrane or sodium bentonite as the preferred repair medium.

8. Don’t just fix the leaking cracks, fix them all

  • If you have multiple cracks in your walls but are only seeking crack repair for the ones that are leaking, the other cracks will eventually leak if you don’t fix the source of the accumulated water.
  • Water follows the path of least resistance and the cracks that weren’t leaking before become the new doorway for the built up water to escape.
  • It is more cost effective to have all your Indianapolis basement Indianapolis foundation crack repairs done at the same time rather than having someone come out multiple times to fix the other cracks as they start to leak.

Basement Indianapolis foundation crack repair is a necessary investment to protect your home and your family from potential problems associated with the cracks. Whether it be structural instability or potential health risks, it is essential to have Indianapolis basement Indianapolis foundation cracks repaired quickly and correctly.
