Why Are Puddles Forming In My Parking Lot?

If you’ve noticed that small puddles form in your parking lot, you’re in the right place. This common issue can be a telltale sign of underlying problems such as water drainage issues, suboptimal asphalt compaction, or flaws in the asphalt sub-base. Ignoring these puddles isn’t just an aesthetic concern – it could lead to more significant damage if not addressed promptly.

In this article, we’ll delve into the reasons behind these parking lot puddle formations and offer solutions to rectify these issues, ensuring your parking lot remains in top condition.

What Causes Puddles To Form In Parking Lots?

Understanding why puddles form in parking lots is key to addressing them effectively. Here are some common causes for parking lot puddles.


Rutting in asphalt surfaces is a common issue characterized by pavement depressions, primarily along vehicle tires’ paths. This pavement deformation can occur in two primary forms.

  • Mix Rutting: This occurs when the asphalt mix deforms under traffic stress, leading to surface indentations.
  • Subgrade Rutting: This type of rutting happens when heavy loads deform the subgrade material beneath the asphalt layer.

These rut formations are prime spots for water accumulation, leading to the formation of puddles. Besides being unsightly, they disrupt the smooth surface of the parking lot and hinder proper water drainage.

What Causes Rutting?

Rutting is often caused by a combination of heavy traffic loads and weaknesses in the pavement structure. In the case of mix rutting, the issue usually lies in the asphalt mix itself, possibly due to poor-quality materials or incorrect mixture proportions. Subgrade rutting, on the other hand, points to problems with the foundation, such as poorly compacted or weak subgrade materials. Both types of rutting are exacerbated by heavy and continuous vehicular pressure, particularly in areas with high temperatures where the asphalt is more susceptible to deformation.

How To Repair Asphalt Rutting

Repairing rutting in a parking lot varies depending on the severity of the problem. Applying a surface treatment like sealcoating or a thin overlay may suffice for minor rutting. However, significant rutting might require more intensive approaches, such as milling the affected area and applying a new asphalt layer. Full-depth reconstruction may be necessary in cases where the rutting has affected the subgrade. This involves removing the damaged pavement layers, improving the subgrade, and replacing the pavement. When done professionally, these repairs not only resolve the puddle issue but also enhance the longevity and performance of the parking lot.


What is Raveling?

Raveling is when the asphalt surface begins to deteriorate, leading to the disintegration of the aggregate particles from the binder. This phenomenon typically starts at the surface and can worsen, further disintegrating the asphalt pavement. Raveling makes the surface rough and brittle, and as the aggregates loosen and separate, they can contribute to water pooling and the formation of puddles. This issue compromises the parking lot’s structural integrity and aesthetic quality.

What Causes Raveling?

Asphalt raveling can be caused by various factors, including aging of the asphalt material, exposure to extreme weather conditions, and poor-quality asphalt mix. Over time, environmental factors like UV radiation, oxygen, and water can break down the asphalt binder, loosening the aggregate. Additionally, the pavement is more prone to raveling if the initial asphalt mix is poorly constituted or improperly compacted during installation.

How To Repair Asphalt Raveling

To address raveling, the extent of the damage needs to be assessed first. In cases of minor raveling, applying a surface treatment such as a slurry seal or micro-surfacing can help bind the loose aggregates and extend the pavement life. More significant raveling might require removing and patching the affected area with a fresh asphalt mix. In severe cases, complete removal and replacement of the affected pavement might be necessary. A&A Asphalt Paving & Concrete Services has the expertise to evaluate the severity of raveling and implement the appropriate repairs, restoring the smoothness and functionality of your parking lot.

Improper Drainage

Improper drainage is a crucial factor in forming puddles in parking lots. If water is not efficiently channeled away from the pavement surface, it accumulates, leading to water pooling. This can be due to several reasons, such as inadequate slope or grading of the parking lot, clogged or insufficient drainage systems, or compaction issues that prevent proper water infiltration. Such conditions not only lead to the formation of puddles but also contribute to other pavement issues like raveling or rutting, exacerbating the overall problem.

How To Fix Improper Parking Lot Drainage

Addressing drainage issues involves a comprehensive approach, starting with a thorough assessment of the existing drainage condition. Solutions may include regrading the parking lot to create an adequate slope for water runoff, cleaning and repairing existing drainage structures, or installing new drainage systems like catch basins or French drains. In some cases, applying permeable pavement options or adding curbing can help direct water flow more effectively. A&A Asphalt Paving & Concrete Services specializes in reconfiguring drainage, ensuring your parking lot remains dry and puddle-free.

Indentations From Heavy Vehicles

Heavy vehicles left on a parking lot can cause surface indentations, subsequently becoming rainwater collection points. These indentations, often resulting from the prolonged pressure of parked heavy vehicles, can deform the asphalt layer, creating depressions where water accumulates. This issue leads to puddle formation and weakens the pavement structure, making it more susceptible to other forms of damage.

How To Fix Asphalt Indentations

Repairing indentations caused by heavy vehicles typically involves resurfacing or patching the affected areas. Depending on the severity, this can range from applying a thin overlay to completely removing and replacing the damaged asphalt section. It is crucial to ensure that the repair is done with high-quality materials and proper compaction techniques to restore the pavement’s integrity and prevent future indentation issues. A&A Asphalt Paving & Concrete Services provides expert solutions for repairing indentations, helping to maintain a level, smooth, and functional parking lot surface.

FAQ About Puddles Forming In Your Parking Lot

Parking lots tend to have puddles primarily due to improper drainage, uneven surfaces, or damage to the asphalt. Issues like rutting, raveling, and compaction problems can lead to water accumulation in specific areas, resulting in puddles.

Water surfacing in your parking lot is often a sign of a high water table or poor drainage. It can also indicate that the sub-base is not effectively draining water away, causing it to seep upwards through cracks or weakened areas in the asphalt.

To fix a puddling driveway, you first need to identify the cause. Solutions may include regrading for better water flow, repairing or sealing cracks to prevent water infiltration, or installing additional drainage solutions like a French drain system.

Fixing ponding in asphalt typically involves correcting the surface grade to promote better drainage. This can be achieved by resurfacing or adding an additional layer of asphalt. In more severe cases, adjusting the underlying subgrade or improving drainage systems might be necessary.
