ENGINEERING CASE STUDY

Solving Drainage Issues on Steep Commercial Parking Lots

AUTHOR: GW George

June 8, 2026

Water is the absolute worst enemy of asphalt. If water sits on your commercial parking lot in Charlottesville or Hot Springs, it will eventually seep through the surface, saturate the base, and destroy the structural integrity of the pavement.

Laser-Guided Topography

Before our heavy fleet ever arrives, we utilize advanced satellite topography and on-site laser transit levels to map the grade of your commercial lot to the millimeter.

The Drainage Arsenal

We don't just guess where the water will go. We engineer it.

  • Catch Basins: We repair, rebuild, and adjust existing storm drains so water flows directly into the municipal system.
  • Asphalt Swales: For long, sloping lots, we pave subtle, engineered channels directly into the asphalt to guide sheet-flow water safely to the edges.
  • 1.5% Minimum Slope: We ensure every square foot of the lot has a minimum 1.5% cross-slope to guarantee positive drainage, eliminating puddles and liability.
