Why Ignoring Small Cracks Leads to Total Base Failure

When water seeps into open cracks and freezes, it expands with enough force to shatter your pavement from the inside out.

Guaranteed Water Infiltration

Every crack acts like a tiny gutter, funneling rainwater directly into the gravel and soil base that supports the entire weight of your asphalt.

Freeze-Thaw Cycle Destruction

In the winter, the trapped water freezes and expands with incredible force, shattering the asphalt from below and turning small cracks into gaping potholes.

Foundation Failure & Potholes

Once the base layer becomes saturated and soft, it can no longer support the pavement. This leads to deep structural failure and the inevitable formation of potholes.

Growing Trip Hazards & Weeds

Unfilled cracks collect debris, encourage weed growth, and widen over time, creating a significant and growing trip-and-fall hazard.

Our Hot-Pour Rubberized Sealing Method

We route, clean, and dry every fissure before flooding it with highly flexible, weather-resistant rubber sealant.

Crack Cleaning & De-Weeding

Using high-powered blowers and wire wheels, we blast all dirt, vegetation, and loose debris out of the cracks to ensure the sealant bonds directly to clean asphalt.

Routing & Preparation (If Needed)

For larger, more significant cracks, we use a specialized machine to "rout" the edges. This creates a small reservoir that allows more sealant to enter for a stronger, more durable repair.

Hot-Pour Sealant Application

We heat our rubberized sealant to over 350°F and skillfully inject it into the cracks. This high temperature ensures it flows to the very bottom and creates a watertight bond.

Final Inspection & Cooling

We lightly squeegee the surface for a smooth finish and inspect our work. The sealant cools and becomes tack-free very quickly, allowing for minimal downtime.

The Result: A Watertight, Resilient Surface

Lock out moisture, stop the freeze-thaw cycle in its tracks, and drastically extend the lifespan of your property's foundation.

Massive Cost Avoidance

The tiny cost of filling a crack today saves you from the thousands of dollars required for patching potholes or completely repaving your entire driveway tomorrow.

Extended Pavement Lifespan

By stopping the cycle of water intrusion and ice damage, you preserve the structural foundation of your asphalt, adding many years to its functional life.

Improved Surface Integrity

Sealing cracks stops them from spreading and interlocking. This maintains a safer, smoother, and more attractive surface for your property.

Asphalt Crack Filling FAQs

Common questions from St. Louis property owners about saving their asphalt.

  • What's the difference between crack filling and crack sealing?

    While often used interchangeably, crack "sealing" typically involves routing the crack to create a reservoir for more material, which is ideal for high-traffic lots. Crack "filling" is the direct injection method we use for most driveways.

  • Can't I just use crack filler from a hardware store?

    DIY cold-pour fillers lack the adhesive strength and flexibility of our professional hot-pour rubberized sealant. They often crack and peel out within a single season.

  • Should I fill cracks before I sealcoat?

    Yes, absolutely. Crack filling is a structural repair, while sealcoating is a surface treatment. For best results, all structural cracks must be sealed first.

  • How long does professional crack filler last?

    Our hot-pour rubberized sealant is designed to flex with the pavement's expansion and contraction, typically lasting for 3 to 5 years.
