If your home or office parking lot shows signs of wear and tear, it may be time to start considering asphalt paving services. Over time, weather and traffic can take a toll on even the most well-maintained asphalt surfaces. A particularly common type of damage in parking lots is a sunken apron. This occurs when the edges of the asphalt begin to sink or crumble, creating an unsightly and potentially dangerous problem. Winter weather can wreak havoc on asphalt paving, causing cracks, potholes, and other damage.

In some cases, this damage may be cosmetic and require nothing more than a few repairs. However, the damage may be more significant in other cases, requiring a complete replacement. When this is the case, it is important to know the signs that it's time to commission sunken apron repair. Here are four signs to look for.

Cracks in the Asphalt

While small cracks are fairly common and usually not cause for concern, large cracks indicate a more serious problem. Cracks can be caused by everything from poor drainage to vehicle weight to shifts in the ground beneath the pavement. If left unrepaired, cracks will only get worse over time, eventually leading to major structural damage.

Sunken Edges

Sunken aprons are often visible from above. When an apron begins to sink, it will often form a depression in the pavement. This depression can be several inches deep in severe cases, making it extremely dangerous for vehicles and pedestrians alike. These low spots usually form around drains or other objects that protrude from the pavement surface. Water collecting in these sunken areas can erode the asphalt and cause it to crumble away.

Potholes

One of the most obvious signs is the presence of potholes. These holes can range in size from small craters to large caverns, and they are often caused by water seeping into the pavement and expanding as it freezes. As the water freezes and thaws over the course of the winter, it will eventually wear away at the asphalt, causing larger and larger holes to form. 

Uneven Surfaces

If you start to notice any irregularities in your asphalt pavement surface, it's a good idea to have it inspected by a professional. These irregularities could be an indication of underlying problems, such as poor drainage or unstable subsoil. Left unchecked, they could lead to major issues down the road.

If you have noticed any of these signs in your parking lot, getting professional help as soon as possible is important. Sunken apron repair is a complex process that experienced professionals should only perform. Attempting to fix it yourself could end up making the problem worse.
