Protecting Lodi's driveways and parking lots from sun and water damage with professional asphalt sealcoating.
Get Your Free EstimateAsphalt sealcoating is the application of a protective liquid layer, typically a refined coal tar or asphalt emulsion, over an existing asphalt surface. This service includes a thorough cleaning of the pavement, addressing minor cracks, and then applying one or two coats of sealer. Its primary purpose is to shield the asphalt binder from oxidation caused by sun exposure and erosion from water, preventing the aggregate from loosening and the surface from becoming brittle.
Our approach to sealcoating begins with a detailed inspection of your Lodi property's asphalt condition. We identify areas needing pre-treatment, like oil stains that require primer, or larger cracks that need hot rubberized crack filling beyond the scope of standard crack sealing. This initial assessment ensures the sealer adheres correctly and provides maximum protection, which is critical for the long-term performance of the application.
For Lodi's climate, sealcoating is particularly important because our hot summers accelerate asphalt oxidation and the occasional heavy rains can quickly penetrate unsealed surfaces. Preventing water intrusion is key to avoiding sub-base erosion and freeze-thaw damage in winter, which can lead to alligator cracking and potholes. A properly sealed surface maintains its structural integrity longer, resisting the typical wear patterns seen in the Central Valley.
Many property owners in Lodi ask about the best time to sealcoat. We generally recommend applying sealer when ambient temperatures are consistently above 50°F (10°C) and no rain is expected for at least 24-48 hours. This allows for proper curing and optimal adhesion. We use commercial-grade sealers formulated for durability, which means they stand up better to vehicle traffic and environmental stressors than many consumer-grade products.
After the sealcoat is applied, we advise keeping traffic off the surface for at least 24-48 hours, depending on temperature and humidity, to allow for complete curing. While the surface may appear dry to the touch sooner, full chemical bonding takes time. We also clearly mark the sealed area with caution tape or cones to prevent accidental disturbance during the curing period, ensuring a uniform and lasting finish.
Lodi's climate, characterized by hot, dry summers and mild, sometimes wet winters, creates specific challenges for asphalt pavements. The intense summer sun causes the asphalt binder to oxidize, leading to a loss of flexibility and the appearance of graying and aggregate exposure. This oxidation process makes the asphalt brittle and prone to cracking, which means water can then penetrate the sub-base.
When water infiltrates cracks, it weakens the underlying aggregate and soil. In Lodi, where clay and loam soils are common, this saturation can lead to instability and settlement, accelerating pavement deterioration. Sealcoating acts as a barrier, preventing both UV degradation and water intrusion, which are the two primary culprits behind asphalt failure in our region.
Beyond protection, sealcoating also restores the pavement's dark, rich color, which improves its aesthetic appeal. A well-maintained, dark surface absorbs more solar radiation, which can help melt light frost or ice faster in cooler months. This proactive maintenance step significantly extends the service life of your asphalt driveway or parking lot, delaying the need for more expensive repairs or full replacement.
We begin by thoroughly cleaning the asphalt surface, removing all dirt, debris, and loose aggregate using power blowers, wire brooms, and sometimes pressure washing. Oil spots are treated with a specialized primer to ensure proper sealer adhesion.
Minor cracks, typically those less than 1/4 inch wide, are cleaned and filled with a rubberized crack sealant. Larger cracks or potholes are repaired using hot asphalt patch material before sealcoating to create a stable, uniform base.
A high-quality, commercial-grade asphalt emulsion or refined coal tar sealer is applied uniformly across the entire surface. We typically apply two coats, allowing adequate drying time between applications, for maximum protection and a consistent finish.
After the final coat, the sealed area is barricaded with caution tape or cones. We advise a minimum of 24-48 hours for curing, depending on weather conditions, before allowing vehicle or pedestrian traffic back onto the freshly sealed pavement.
