What Is Concrete Crack Filler?

Concrete crack filler is a material used to fill small cracks in concrete, and it’s generally applied as a quick solution for surface issues.

Different types of fillers—such as caulk, concrete sealers, or specialized cement filler for cracks—are designed to plug cracks and prevent further moisture infiltration.

The idea is that by sealing off the crack, you can limit damage to your concrete in the short term.

Concrete Sealers vs. Concrete Sealants

Both concrete sealers and concrete sealants are commonly used for filling cracks, but they serve slightly different purposes:

Concrete Sealers: Typically used to protect the surface of the concrete, these form a thin protective layer, ideal for smaller cracks or as a preventative measure.
Concrete Sealants: Sealants tend to be more flexible and are suited for wider cracks. They’re often silicone or polyurethane-based, offering durability and flexibility to withstand temperature changes.

How to Identify the Best Concrete Crack Filler for Your Crack

Different cracks require different types of fillers. Here are some tips for choosing the right cement filler for cracks:

Hairline Cracks: Use a concrete sealer that seeps into the crack and provides surface protection.
Wider Cracks: Opt for a sealant that can handle expansion and contraction.
Deep Cracks: These need a filler that can handle load-bearing. Using a backer rod or foam before applying the filler can improve durability.

The Limits of Concrete Crack Filler: Addressing the Root Cause

While concrete crack filler can help with surface issues, it doesn’t address the root cause of the cracking. In Missouri, factors like soil movement, temperature fluctuations, and water infiltration can lead to persistent cracking. Some common reasons for cracking include:

Soil Shifting or Erosion: Weak or shifting soil can cause concrete to lose support, leading to sinking and cracking.
Freeze-Thaw Cycles: When water enters cracks and freezes, it expands, making cracks wider over time.
Water Damage: Continuous exposure to moisture weakens concrete over time, especially in Missouri’s wet seasons.

If your concrete is cracking due to sinking or shifting soil, filling it with a sealant may only be a temporary solution. In such cases, concrete lifting is a more effective, long-term repair option.

What Is Concrete Lifting?

Concrete lifting is a specialized technique for lifting and leveling sinking concrete slabs. At Foundation Recovery Systems, we use advanced polyurethane injection technology to raise and stabilize concrete. The process involves injecting a lightweight expanding foam beneath the slab, which fills gaps in the soil and raises the slab to its original position.

Benefits of Concrete Lifting

Long-Term Solution: Rather than simply filling cracks, this method repairs the underlying problem of sinking soil, closing cracks, and preventing future damage.
Cost-Effective: Compared to replacement, concrete lifting is often more affordable and quicker.
Environmentally Friendly: The process is minimally invasive, with little disruption to the surrounding environment.

How to Prevent Future Concrete Cracks

Preventing concrete cracks often comes down to simple maintenance and smart planning. Here’s how you can help extend the life of your concrete:

Gutter Maintenance: Make sure your gutters are clean and that downspouts direct water away from concrete areas. Proper drainage helps avoid water pooling around your concrete, which can weaken the soil and lead to cracking.
Freeze-Thaw Protection: Avoid letting water freeze on concrete surfaces. Apply a concrete sealer to protect against freeze-thaw cycles, or add traction materials in winter to prevent ice buildup.
Weed Control in Expansion Joints: Don’t let weeds take over expansion joints. They can push the concrete apart, leading to further cracking. Consider using a sealant to prevent weed growth.

Concrete Crack Filler FAQ’s

Do I need to reapply concrete crack filler periodically?

Yes, since crack filler is a temporary fix, it may need reapplication, especially in areas subject to frequent moisture and temperature changes.

Are there specific conditions when crack filler doesn’t work?

Crack filler may not work on active or moving cracks, and it’s generally ineffective for cracks caused by structural issues or sinking.

What type of crack filler is best for freeze-thaw environments like Missouri?

Look for flexible, weather-resistant sealants designed to withstand freeze-thaw cycles.
