How to Correct Sunken Surfaces on an Asphalt Parking Lot, Queens, New York

Uneven asphalt paving can affect your business's visual appeal and make it difficult for customers to park. Luckily, professionals can fix this problem to restore the functionality of your parking lot. Here’s more information about this issue to help you correct it.

How Asphalt Paving Develops Sunken Spots 

Underneath the asphalt, there are several inches of gravel on top of compacted soil. Professionals must compact the ground during installation to create this even surface. Without properly compacted land or sufficient amounts of gravel, pavement can sink over time. Poor construction is likely the culprit if the parking lot also has imprints from tires.

Sunken spots also occur when tree roots damage the foundation beneath the asphalt, creating voids that the surface material must fill.

Even poor drainage and water pooling can cause unevenness due to the freeze-thaw cycle. Drainage may be to blame if you notice that the pavement rises during the winter and then buckles when the ice melts.

Potential Solutions for Uneven Pavement

To fill sunken areas, the contractor first removes any dust, weeds, or dirt in the affected spot to help the new asphalt adhere. Next, they fill the hole with new asphalt mix, smoothing it down in layers. 

Drainage and installation issues typically call for full replacement to address underlying foundation problems. A professional will identify any improperly compacted soil under the parking lot.
