What Are Drainage Issues?

Drainage issues occur when water accumulates or flows improperly across your pavement surface rather than draining away. In driveways, this might mean puddles near garage thresholds or the house, which can seep under the asphalt and trigger frost heave during Colorado’s freeze-thaw cycles. In parking lots, even small depressions or lack of a proper slope (less than 1–2%) can cause water pooling, which can cause your asphalt to deteriorate much faster.

Why Address Drainage Problems Early?

When water isn’t properly channeled off asphalt, it penetrates surface cracks and softens the base, setting the stage for potholes, subsidence, and cracking. By getting ahead of these problems, you improve safety, reduce trip and vehicle damage hazards, and preserve your investment.

Our Drainage Assessment Process

  • Property Visit and Visual Audit: We inspect water pooling, slope, and asphalt damage.
  • Slope and Flow Testing: Using precision tools, we measure surface grades and identify areas needed for proper runoff.
  • Damage Analysis: We evaluate issues like pavement subsidence, edge cracking, and heaving linked to drainage failures.
  • Solution Recommendations: Our report outlines all available full-surface options. These can include grading adjustments, asphalt curbing and small trenching, installing drainage systems, using permeable pavement material, general maintenance such as cleaning, drainage clearing, damage repair, or addressing specific seasonal needs.

Things to Consider Before Fixing Drainage Issues

  • Slope severity: The general recommendation is a 2% slope for driveways and a minimum of 1.5% for parking lots. If poor drainage is caused by an improper slope, regrading can help effectively direct the water flow.
  • Damage extent: Minor pooling may only require resurfacing or regrading; deeper erosion may call for sub-surface fixes and asphalt repair.
  • Above or Below Ground Solutions: Swales, rock beds, and surface drains are easier to install and maintain. Subsurface drains such as French drains, dry wells, and sump pumps are more effective for serious issues, and are installed underground.
  • Climate impact: Colorado’s cycles of summer monsoons and winter freezes demand drainage strategies designed for dynamic weather patterns.
