Learn how A-1's concrete caulking process seals cracks, prevents damage from worsening, and keeps your concrete looking great.
Concrete is tough, but it's not invincible. Over time, even the strongest slabs develop cracks and gaps that invite water, weeds, and unwanted settling.
But don’t worry! Those cracks can be stopped in their tracks with concrete caulking, and in this article, we’re diving into A-1 Concrete Leveling’s expert method for sealing cracks and gaps.
Why Caulking Concrete Matters
Cracks in your concrete might seem like just a cosmetic issue, but they’re sneaky little pathways for trouble. Here's what can happen if those gaps are left unsealed:
- Worsening Cracks: Water slips in, freezes, expands, and forces cracks to grow. Hello, freeze-thaw cycles!
- Settling Slabs: Moisture erodes the soil beneath the slab, leaving concrete unsupported and prone to sinking.
- Weeds: Cracks become a perfect hideout for weeds. They’re not just unsightly, they’re stubborn and hard to remove.
Concrete caulking helps stop all that in its tracks by creating a flexible, watertight seal that moves with your concrete and stands up to the elements.
The A-1 Concrete Caulking Process
Caulking concrete correctly is more than just squeezing caulk in a crack. It requires precision, the right materials, and practice. Here’s how our pros do it:
Step 1: Clean and Prep the Crack
A strong bond starts with a clean slate. We remove any dirt, debris, weeds, or old caulk from the crack or joint so the new caulk can adhere properly.
Step 2: Apply the Caulk
We use high-quality, flexible concrete caulk that’s specifically designed for exterior slabs. It flexes with the natural expansion and contraction of your concrete, ensuring a long-lasting, watertight seal.
If the crack is wide or deep, we may insert backer rod (a foam filler) to help the caulk sit at just the right depth for optimal performance.
Step 3: Tool and Smooth
We smooth the caulk to create a clean, polished finish. This not only looks better but also helps ensure solid contact with the concrete to improve durability.
Step 4: Optional Sand or Stone Finish
As an optional final step, sand or stone can be added to the caulk while it's still wet to blend the repair in with the surrounding concrete. This adds color and texture.
Frequently Asked Questions About Concrete Caulking
Can I bundle caulking with other services?
Absolutely. In fact, caulking is often required at the time of concrete leveling to maintain the warranty. Bundling it with cleaning and sealing can make your concrete look new again while extending its lifespan.
Can I DIY my own caulking job?
Yes! Concrete caulking can be done as a DIY project. However, for the best looking results, it's better to leave it to the pros who caulk concrete day in and day out. (It's harder than it looks!)

What kind of caulk do you use?
We use a high-quality, flexible caulk that is meant specifically for use on concrete cracks and joints.
Concrete caulk is flexible and moves with your concrete, meaning it won't crack or flake off like rigid mortars or concrete patch kits.
