How Drainage Issues Lead to Asphalt Damage—And How to Fix Them

Water is one of asphalt’s worst enemies. It might not seem like a major concern at first glance, but poor drainage is one of the leading causes of pavement failure. When left unchecked, even minor standing water can cause serious damage to roads, parking lots, and driveways—costing property owners thousands in repairs.

If you’ve ever seen a smooth blacktop surface suddenly riddled with cracks, potholes, or sinking edges, chances are water was at the root of the problem.

What Happens When Water Sits on Asphalt?

When drainage isn’t properly managed, water collects on the surface and eventually seeps into small cracks. As it penetrates the pavement layers, it starts weakening the subbase—the compacted layer beneath the asphalt that gives it structure and support.

In colder months, this water freezes and expands. When it thaws, it leaves behind gaps, voids, and soft spots. The result? Widespread cracking, potholes, and even total pavement failure in extreme cases.

In warmer months, standing water accelerates oxidation and surface erosion. You’ll often see faded asphalt, early rutting, or depressions forming around heavy-traffic zones like loading docks or parking stalls.

Common Signs of Drainage-Related Asphalt Damage

  • Water pooling along curbs or low spots
  • Surface cracks that appear after storms
  • Sinkholes or soft areas near catch basins
  • Frequent pothole development in the same location
  • Edges breaking away or separating from sidewalks and landscaping

Even brand-new pavement can deteriorate quickly if water isn’t directed away from the surface efficiently.

How to Fix and Prevent Drainage Issues in Asphalt

1. Regrade or Reslope Surface Areas

If your lot has low points or flat sections, water will naturally pool there. Regrading the asphalt surface or adjusting slope angles can help redirect runoff.

2. Install or Repair Catch Basins & Drains

Catch basins, trench drains, and storm inlets collect and channel water away from your pavement. These systems need to be properly placed, maintained, and free of clogs to work effectively.

3. Upgrade Your Subbase

A poorly compacted or outdated subbase won’t support proper drainage. Reinforcing this layer during paving or resurfacing provides a stable foundation that resists water intrusion.

4. Crack Sealing & Sealcoating

Preventative maintenance like crack sealing and sealcoating stops water from penetrating asphalt in the first place. These services are especially effective when done in spring or early fall.

5. Edge Reinforcement

Strengthening pavement edges and transitions to concrete or landscaping helps prevent erosion caused by runoff or gutter overflows.

Why Proper Drainage is a Long-Term Investment

Think of drainage like insurance for your asphalt. A well-designed system protects your investment, minimizes emergency repairs, and improves safety for vehicles and pedestrians. It also supports better compliance with environmental regulations and ADA standards in commercial spaces.
