Caulking / Joint Sealants (Outdoor Concrete)
Designed for Commercial Parking Lot Surfaces
Outdoor concrete is exposed to the elements year-round, and Michigan’s freeze-thaw cycles are no joke. One of the most effective ways to protect your investment—especially in high-traffic areas like commercial parking lots—is with high-quality caulking and joint sealants. At The Crack Medic, we specialize in sealing concrete joints to prevent water infiltration, slab shifting, and surface deterioration.
Some customers may only require expansion joint caulking without surface sealing. That’s no problem—our services can be tailored to match your needs, whether it's just joint caulking or full joint and surface sealing.
Why Joint Caulking Matters
- Blocks Water Intrusion: Prevents pooling and freezing beneath slabs.
- Extends Concrete Lifespan: Prevents joint movement and slab shifting caused by water infiltration.
- Reduces Trip Hazards: Keeps slabs level and walkways safe.
- Saves You Money: Reduces the need for costly repairs or slab replacement.
- Boosts Overall Durability: Joint caulking and surface sealing work together for long-lasting results.
Why Surface Sealing Matters
- Protects the Surface: Shields against water and chemical damage.
- Prevents Spalling: Stops freeze-thaw damage that causes surface flaking.
- Improves Appearance: Gives concrete a cleaner, newer, and more uniform look.
- Boosts Overall Durability: Joint caulking and surface sealing work together for long-lasting results.
Surface Prep: Shot Blasting > Power Washing
We prefer shot blasting over power washing because it's cleaner, faster, and far more effective at preparing outdoor concrete surfaces. Power washing is messy, labor-intensive, and leaves moisture behind—making it unreliable for a strong seal. Shot blasting removes debris and opens the concrete pores for optimal adhesion without the mess.
Outdoor Challenges: Michigan Winters & Plow Damage
Plow trucks and freeze-thaw cycles are brutal on outdoor joint sealants. We recommend regular inspections and re-caulking as needed—especially in areas exposed to snow plowing and standing water. Sealants exposed to sunlight and heavy wear typically need replacement every few years.
Added Benefits
- Aesthetics: We use clear sealants that blend well with most concrete surfaces, helping maintain a clean, uniform look. (Note: Color matching is not guaranteed due to aging and variations in concrete.)
- Structural Integrity: Maintains slab alignment and prevents heaving.
- Peace of Mind: Professionally sealed joints mean fewer surprises come spring.
