Is the Foundation Crack a Structural Defect?

Nearly 100% of concrete foundations crack. This is because as the concrete cures, it shrinks in volume. This shrinkage causes stress on the concrete and to relieve that stress, it cracks. This is okay and the foundation is designed to handle the crack. The most common places on a foundation wall where this occurs at the corner of a window, where the wall "steps down" or in the middle of a long wall. These cracks are nearly vertical in nature and usually 1/2" or less. We recommend using a urethane foam for these cracks.

Stop Leaking Cracks in Concrete Basements

A basement crack can let water leak in when the concrete cracks. This water can cause mold and mildew to grow in a basement. By stopping water that leaks through a foundation crack, a basement will stay dry. Now you can install a home entertainment area, insulation or just keep your valuable family possessions safe.

All Around Foundation Waterproofing LLC, uses Hydrophobic polyurethanes to stop water leaks.  Injecting Hydrophobic polyurethane foam is the best way to stop a foundation wall crack leak. This is because the liquid urethane fills the entire foundation crack. Once in the concrete crack, it begins to foam inside the basement crack. The expanding foam completely fills the basement crack and prevents future water leaks. Water will now remain outside of the basement wall and not be able to penetrate into the interior.

Fast and Inexpensive Concrete Crack Repair

A typical 8' foundation crack can be repaired in one hour. This is because there is no drilling or chiseling needed to widen the foundation crack. The low viscosity polyurethane can enter even hairline cracks with ease and stop your basement water leak. 

 Hhydrophobic Polyurethane Foam Concrete Foundation Crack Repair Advantages

  • Closed cell foam stops basement water leaks
  • Water stays outside of the basement
  • Strong bond to foundation concrete
  • Fills the basement wall crack entirely
  • Easy to use
  • No drilling or chiseling

Urethane Foam Foundation Crack Repair Vs. Hydraulic Cement Patching

To stop water from leaking into a concrete basement or concrete foundation crack, liquid urethane foam can be injected into the concrete crack. On contact with water, the liquid urethane foams and expands inside the crack.

Concrete basement crack repair by urethane injection entirely fills the crack. Not only from the bottom to the top, but the entire width of the foundation wall. The water stays on the outside of the foundation and the basement contents are safe. The foam created is a closed-cell structure that will not allow water to work its way through the basement crack. The finished foam bonds tightly to the surrounding concrete to ensure that water does not push the foam out of the foundation crack. Once the urethane has foamed and expanded inside the foundation crack, water cannot leak into the basement again.

In comparison, a patch repair using hydraulic cement is much less reliable. Hydraulic cement must have the crack chiseled out into a vee-notch. This is a long and messy process. The chiseled out notch is only a few inches deep. The hydraulic cement cannot be placed into the entire width of the concrete wall. Therefore, water still gets into the basement crack from the outside. Over time salts develop which break the bond between the hydraulic cement and the existing concrete foundation. This allows water to leak again into the basement.

A patch repair covers the inside surface of a foundation crack. This is a weakly bonded repair that the water can push off of the wall and allow water to leak into the basement.

Repair from the inside means no digging or messy excavation.

Concrete basement and foundation crack repair is done from the inside of the basement. The home's outside landscaping does not have to be removed and the foundation excavated for the leak repair. Also, there is no drilling or chiseling to perform a foundation crack leak repair using Applied Technologies' products. The concrete basement crack is filled entirely by the concrete crack injection repair material. This stops water from leaking into a basement and keeps the possessions dry.
