Crack Filling
Every crack in your asphalt is a door for water, sand, and weeds to get into the base below the pavement. Once water gets under the asphalt, freeze-thaw cycles and traffic loading turn small cracks into potholes — fast. Trinity Striping seals cracks with hot-applied rubberized sealant that bonds to the asphalt walls, flexes with temperature changes, and keeps water out. Staying ahead of cracks is the cheapest pavement maintenance you can buy.
What We Do
What's Included
Every crack fillingproject from Trinity Striping covers the full scope so you don't have to coordinate a second vendor. Typical work on a job looks like this:
- Hot-applied rubberized crack sealant
- Longitudinal, transverse, and block crack repair
- Seat joint sealing
- Reflective crack filling
- Crack prep (routing, cleaning, drying)
- Elastomeric sealant that flexes with temperature
- Stopping weed growth through cracks
- Pre-sealcoat crack repair
Our Process
How a Project Gets Done
Every job follows the same proven steps, so the result is consistent whether it's a small driveway or a multi-acre commercial lot.
- Step 01
Crack Inspection
We walk the lot and flag every crack that's worth sealing — typically anything from a quarter inch up to about an inch and a half wide.
- Step 02
Cleaning & Drying
Cracks are blown out with a high-pressure blower to remove dirt, sand, and moisture so sealant can bond to clean asphalt.
- Step 03
Hot Sealant Application
We melt rubberized crack sealant in a dedicated melter to around 380°F and apply it with a wand so it penetrates the full depth of the crack.
- Step 04
Leveling
We squeegee the sealant to a flush or slightly crowned finish so traffic rolls over the repair without catching on it.
- Step 05
Cool & Return to Service
Sealant cools within minutes and can typically be driven over in 30 minutes. Large fills may need slightly longer.
Why It Matters
The Case for Crack Filling
Stops Water Damage
Sealing cracks keeps water out of the base. A dry base is a strong base, and a strong base lasts.
Prevents Potholes
Potholes almost always start as an unsealed crack. Filling cracks is the fastest way to keep your lot pothole-free.
Kills Weed Growth
Weeds root through open cracks. A sealed crack blocks light and root access, so the weeds stop coming back.
Prep for Sealcoating
Sealcoating doesn't bridge cracks, so crack filling has to happen first. Doing both on the same visit protects the lot for years.

Frequently Asked
Crack Filling FAQ
How big a crack can you fill?
We seal cracks from about a quarter inch up to around an inch and a half wide. Wider separations, deep potholes, or alligator-cracked areas aren't really a sealing job anymore — they need a patch or mill-and-overlay.
What's the difference between crack filling and crack sealing?
In everyday use, the terms are interchangeable. Technically, 'filling' describes filling a static crack with a simpler product, while 'sealing' uses a higher-grade elastomeric sealant that flexes with temperature. We use hot-applied rubberized sealant, which is the sealing-grade product.
When is the best time to fill cracks?
Any time the pavement is dry. In South Florida, mild winter months and drier stretches in spring and fall are ideal, but we can fill year-round as long as there's no rain on site.
How long will a crack fill last?
A good hot-applied fill typically lasts 3 to 5 years, depending on traffic load, sun exposure, and how much the pavement moves. Filling before sealcoating and re-inspecting annually is the sweet spot.
Do you fill cracks before sealcoating?
Yes. Sealer won't bridge a crack — it just drops into it. Filling first means the seal stays uniform and water stays out.
