Let's Talk About Drainage

When water falls on your parking lot or roadway, where does it go? Questions like this probably don’t keep you up at night, but when deterioration and/or damage to your surface affect the proper drainage your pavement was designed to have, it becomes an issue that needs to be addressed.

Let's Talk About Drainage

Water, Water Everywhere

Standing water is not only a safety hazard for drivers, bicyclists, and pedestrians but is also one of the most damaging elements to your pavement. The remedy is a little thing we call slope. Paved surfaces are typically designed to have a minimum of a 1 percent slope. This allows water to travel via flow lines to lower elevation areas such as curbs, dry wells, and retention areas, which divert moisture away from the paved surface.

Water, along with oxygen and UV rays, damages the chemical bonds that give pavements their strength. When these bonds break apart, the pavement becomes brittle and small fractures in the surface become vulnerable to moisture, debris, and vehicle force. As the deterioration worsens, larger cracks appear, which allow the foundation to become susceptible to the damaging effects of water as well.

Whether the source of water is natural (rain) or man-made (irrigation, sprinklers, etc.), preventing water from pooling on your asphalt surface reduces its deteriorating effects and limits the amount of moisture saturation to underlying layers.

Staining or Draining

Obviously when water is present, it is easier to see those areas where ponding or poor drainage is occurring. Though trouble areas can be more difficult to spot during dry conditions, there are some telltale signs you can look for. Dirt stains, standing debris, or areas of significant concentrated cracking, i.e., “alligatoring,” should trigger the need for further evaluation by a professional estimator. Also, if water is not properly getting to a concrete valley gutter or curb, deterioration will be evident where the asphalt and concrete adjoin.

Go With The Flow

You don’t have to break the bank to correct all drainage issues. Minor repairs such as asphalt skin patching can alleviate depressed surface areas and restore proper flow.

Let us help you determine whether your parking lot or roadway has appropriate drainage. Otherwise, you might be throwing your money (and your surface) down the drain.
