Concrete Foam Injections: The Best Fix for Sunken Concrete?

Best fix for sunken concrete Houston TX

Do you have sinking concrete?

The sinking process of concrete is a natural occurrence that happens over time. It’s due to the weight of the concrete and can put your building at risk for cracking or collapsing. Luckily there are some ways you can prevent this from happening by injecting foam into the foundation to lift the concrete. This will provide support and stop those pesky cracks altogether!

What are foam concrete injections?

Concrete injections consist of injecting a foam material into the ground to support sinking concrete. During the injection process, contractors drill holes in the foundation and pump liquid polymer or polyurethane into the ground through a hose.

The foam that is injected into the ground will expand and cause the concrete to float back up to its original position. These injections are great for repairing sinking foundations because they can support large loads of weight! The injections can prevent the formation of cracks in buildings, garages, or homes.

Why do you need to inject foam?

The continuous weight of concrete will cause it to sink. This can be a huge problem, as the resulting damage could lead to cracks in your exterior walls and even collapse! If done correctly, these injections can provide support for your sinking foundation and prevent this from happening altogether!

Foam concrete injections have been found effective at preventing damage to:

  • Backyard patios
  • Sidewalks
  • Front or back cement stairs
  • The foundation of houses
  • Driveways
  • The foundation of businesses
  • Porches
  • Pool decks
  • Anything that involves sinking concrete!

How often should you have foam injections done?

It depends on the size of your project or building. If it’s an entire house, we recommend doing it once every 2 to 5 years to ensure that none of the surrounding areas sink. With smaller projects like patios, sidewalks, or concrete slabs, you can do it whenever you see that theirs a problem.

What happens if you have sinking concrete?

If you leave it by itself, the concrete will continue sinking until it collapses. There are often times when the surrounding areas won’t be affected too much. But if they are, that could lead to some serious problems, especially for your house!

If this problem occurs, there are some signs you may see around your property:

  • Cracks in exterior walls and flooring (especially near the edges)
  • Doors and windows that stick or don’t work properly
  • Damage to interior wall surfaces such as drywall cracking and water seepage
  • Sloping floors or sloping walls
  • Cracking concrete

Why should you care?

These cracks are not only unsightly but can be potentially dangerous for anyone entering or exiting your building. They also increase the risk of mold growth inside your home due to excess moisture from increased water seepage in the cracks around your house. You don’t want that!

Are there risks associated with foam injections?

Not at all! The injection process consists of polyurethane or liquid polymer material that is non-hazardous, water-resistant, and chemical resistant. It has low toxicity levels, making it safe for the environment while preventing damage to the foundation. Polyurethane foam injections are also very cost-effective and have a quick return on investment.
