What to Do About Puddles in my Parking Lot

Puddle in Asphalt Parking Lot

Have you ever stepped out of your car, after pulling into a parking space, and found your foot sinking in water?  Parking lot puddles are not only an annoyance to your customers, but they can cause bigger problems if not repaired immediately.


RoadStar Paving, with over three generations of asphalt paving and repair experience, has seen its share of puddles in the Pittsburgh area.  They understand the challenges these standing pools of water can have on your customers and your business. Here are a few things to know about what causes puddles in your parking lot and what problems they can lead to.

Causes of Puddle Formation

Don’t let an abundance of rain be the reason for your parking lot puddles.  Yes, it certainly helps fill the indentation, but it is not the root of why the puddle has formed.  Let’s take a look at some of the common causes.

  • Indentations left by vehicles or equipment – The flexibility of asphalt, which helps prevent cracking and heaving due to its natural movement, can also cause pavement rutting—indentations along the wheel paths of cars.  If large vehicles or heavy equipment have been on your parking lot for an extended period of time, there is the possibility that depressions in your pavement have occurred.  Cars repeatedly parking in the same spot have the same effect.
  • Poor compaction during installation – If your asphalt parking lot was not properly compacted, it is susceptible to rutting and grade depression.  Compaction is what makes asphalt durable and strong.  Therefore, if the proper technique or equipment was not used during installation, then you may be experiencing puddles due to it.
  • Inadequate Drainage –Proper drainage should be determined at the time of installation, but if it wasn’t or if it was done incorrectly, then the puddles may be the result of it.  Some asphalt paving companies in Pittsburgh may use porous asphalt, which allows water to filter through the asphalt layers and move to waterways. Many parking lots are sloped to allow for proper drainage.
  • Improperly installed sub-base – The sub-base provides structural integrity and helps prevent cracking and sinking of your asphalt pavement.  If it is not installed correctly or the proper materials are not used, then the structural integrity is compromised.

Problems Caused by Puddles

Water coming into contact with your parking lot is normal and unavoidable.  It only becomes a problem when it pools on top of the asphalt surface and remains for a period of time.  Standing water accelerates the breakdown of asphalt. If water seeps into cracks and reaches the base layer, you will experience even bigger issues.  During colder weather, the expansion and contraction caused by freezing and thawing will further damage the asphalt.

When puddles become regular visitors to your parking lot, it is important that you identify the cause and resolve it immediately. Hiring a professional and reputable asphalt paving company to repair your Pittsburgh parking lot will prevent bigger, more expensive problems in the future.
