Commercial · San Francisco, CA
Cracks spread fast in busy parking lots, letting water reach the base and turning small defects into potholes. Apex Asphalt San Francisco provides professional crack sealing in San Francisco to protect your pavement, reduce trip hazards, and stretch the life of your asphalt.
Prep makes or breaks crack sealing, so we start with a clean, dry, sound crack. We route when needed to create a uniform reservoir, then blow out debris with high-pressure air and heat-lance or torch-dry damp edges so the sealant bonds. For wide or unstable cracks, we install backer rod to control sealant depth and avoid three-sided adhesion. The goal is a flexible seal over a clean substrate, not a surface smear that peels off in traffic.
San Francisco’s mix of coastal moisture, fog, and stop-and-go traffic means cracks can pump water and fines out of the base every time a tire hits. We select traffic-rated, rubberized hot-pour crack sealant or a cold-applied material only when site conditions require it, and we apply it at manufacturer temperature ranges using a direct-fire melter/kettle with an agitation system. After filling, we squeegee band the sealant to bridge the crack edges and improve water resistance, then apply a light sand or detack material where needed to reduce tracking. The finished look is neat, uniform, and built for turning movements, delivery trucks, and daily stall traffic.
Customers choose us because we treat crack sealing as preventative maintenance with measurable results. We give a written scope that separates crack sealing from sealcoating and patching, so you are not paying for the wrong fix. Crews use commercial routing, blowers, and melters, and we schedule work to minimize disruption with clear cones, signage, and cure-time guidance. You get straightforward communication, consistent workmanship, and a plan that fits your budget cycle.
At closeout, we walk the lot with you and confirm that active cracks, joints near curb returns, and high-stress areas at drive lanes are properly sealed, and we flag cracks that are too wide or alligatored for sealant alone. You receive a clean site, photos on request, and maintenance recommendations, including when to sealcoat, when to spot patch, and how to keep water from entering at utility cuts and depressions. We also provide practical re-open times based on temperature, traffic, and material type. The result is a tighter pavement surface that slows crack growth and helps prevent potholes and base failure.
Yes. We are a licensed and insured asphalt contractor, and we provide written estimates with a clear scope of work, materials, and scheduling.
Light foot traffic is often possible the same day, while vehicle traffic typically needs more time depending on temperature, thickness, and site conditions. We give specific reopen times and protect soft edges during the first days of curing.
Yes, when failures are isolated. We can sawcut and remove damaged sections, rebuild base, and place hot-mix asphalt patches, then blend with crack sealing or a resurfacing plan if the surrounding pavement is near end-of-life.
Yes. We can stripe with traffic paint or thermoplastic where appropriate and help you plan stall widths, accessible spaces, and access aisles based on current site conditions and striping best practices.
Keep water moving off the surface, seal cracks early, avoid turning wheels in place when the pavement is hot, and schedule sealcoating on a maintenance cycle after proper cure. We can set a maintenance plan based on your traffic and exposure.
Crack sealing is one of the highest-ROI asphalt maintenance services for commercial parking lots, HOAs, and mixed-use properties. By sealing working cracks before water and debris reach the aggregate base, you reduce pothole formation, edge raveling, and premature failure. Apex Asphalt San Francisco focuses on clean prep, correct material selection, and professional application methods so your repairs last through traffic and weather cycles.
Effective crack sealing starts with selecting the right cracks. Linear cracks and moderate-width working cracks respond well to routing, cleaning, and filling with rubberized hot-pour material, while alligator cracking and failing areas usually need sawcut and remove, infrared repair, or full-depth patching. We evaluate the pavement condition, drainage, and traffic patterns, then recommend the right mix of crack sealing, spot patching, and sealcoating so you do not waste money sealing pavement that is already structurally compromised.
Our process is built around adhesion and flexibility. We remove vegetation and loose material, route when appropriate to create consistent sealant geometry, and use high-pressure air and heat to eliminate dust and moisture. Sealant is installed at manufacturer-specified application temperatures using a melter/kettle with agitation, then tooled with a squeegee band to protect the crack edges from water intrusion. Where tracking is a concern, we apply a detack sand to keep tires and shoes clean while the material cools.
If you manage a property in San Francisco, crack sealing is best scheduled before the rainy season and whenever cracks first appear, not after they widen and break apart. Ask us for a written estimate and a maintenance plan that coordinates crack sealing with striping, ADA access routes, and future resurfacing timelines. You will get a practical scope, professional workmanship, and a parking lot that stays safer and serviceable longer.
