🕳️ What Causes Asphalt Potholes (And How to Prevent Them)

By Mountain View Paving | South Bay’s Trusted Asphalt Experts

We’ve all seen them — potholes that jar your tires, ruin your morning commute, or become a hazard in parking lots and driveways.

But what actually causes potholes to form in asphalt? And more importantly — how do you stop them before they damage your pavement, vehicles, or your budget?

At Mountain View Paving, we repair potholes every week across Mountain View, Palo Alto, Sunnyvale, and surrounding areas — and we know the key to preventing them lies in timing, maintenance, and proper drainage.

💥 What Causes Asphalt Potholes?

Potholes happen when moisture — usually from rain — enters small cracks in the pavement. As the water seeps below the surface:

The asphalt base weakens
Vehicles and traffic apply pressure
The surface collapses or crumbles under stress

It’s not just about bad asphalt — it’s usually about delayed maintenance and poor water management.

🧱 Other Common Contributors:

Freeze-thaw cycles (water expands as it freezes)
Poor compaction during installation
Heavy vehicle traffic in areas with thin pavement
Old, unsealed asphalt with fading oils and open pores

🚧 Why You Shouldn’t Ignore Potholes

Even a small pothole can:

Grow quickly from tire pressure and rain
Damage vehicles and increase liability
Create trip hazards for pedestrians
Lead to full surface failure and costly resurfacing

🔧 How Mountain View Paving Repairs Potholes

We don’t do “band-aid” patches — we do it right:

✅ Remove all loose material
✅ Clean and prep the area
✅ Add hot mix asphalt
✅ Compact and level for a seamless surface
✅ Optionally seal or stripe after repair

We also check for drainage or subbase problems that may have caused it — because we believe in fixing the root, not just the hole.

✅ How to Prevent Potholes in the First Place

Seal coat every 2–3 years to protect the surface
Crack fill early before water gets in
Fix drainage issues before rainy season
Schedule annual inspections with a trusted paving team
Avoid patchy DIY repairs that trap moisture underneath

📍 Bay Area Conditions = High Risk

With Bay Area rain patterns, dry summers, and aging infrastructure, potholes form fast. The best protection? Staying ahead of them with a local partner who knows the terrain.
