Settlement, Depressions, and Low Areas — Especially Near Garage Floors and Walkways

Asphalt surfaces that develop settlement, depressions, or low areas often show uneven sections or sunken spots where water may collect. Although these conditions can appear anywhere in an asphalt driveway, private road, or pipe stem, they are especially common where asphalt meets a garage floor, concrete apron, or adjacent walkway.

This type of settlement is more than a cosmetic issue. When asphalt settles below the elevation of nearby concrete, it creates a gap that allows water to infiltrate. That water can wash out supporting soil and create voids or cavities beneath the concrete. During colder months, infiltrated moisture can also freeze and expand.

The combined effects of soil washout and freeze–thaw action can lead to cracking, settling, and long-term damage to concrete surfaces. This is particularly serious at the garage slab, where repeated freeze–thaw cycles and ongoing moisture exposure can crack the garage floor, cause slab settlement, and in some cases contribute to damage at the foundation of the house.

Patching is sometimes used as a temporary stop-gap to address immediate safety or usability concerns. However, asphalt patches often stand out visually and can make a surface look worse rather than better. More importantly, they rarely hold their elevation and commonly crack, sink, or shift again.

When settlement, depressions, or low areas are present—especially near garage floors or walkways—continued patching typically provides only short-term results and does not correct the underlying elevation and drainage problems. Replacing the asphalt surface is usually the safer and more effective long-term solution.

Holes Forming in the Asphalt Surface

Holes often develop when cracking allows water to penetrate the asphalt surface. Once moisture enters through cracks, it is funneled into the underlying layers instead of shedding off the surface.

As water collects beneath the asphalt, it saturates the material below and weakens the surrounding pavement. Repeated freeze–thaw cycles and ongoing traffic cause cracked areas and alligator-patterned sections to break apart, allowing small openings to expand rapidly into deeper and wider holes. As moisture continues to infiltrate, new holes can form nearby as surrounding areas deteriorate.

Once holes begin forming, spot repairs rarely blend well and often fail quickly. These areas can damage vehicles and accelerate deterioration across adjacent sections of pavement.

When holes are present, repair and sealcoating are typically no longer practical or cost-effective options.

When Replacement Becomes the Better Long-Term Choice

If one or more of these conditions—widespread cracking, settlement or depressions, or holes forming in the surface—are present, repair and sealcoating are typically no longer practical or cost-effective solutions.

Replacing the asphalt before conditions worsen allows surface elevations, drainage, and transitions to garage floors and walkways to be corrected properly. Acting sooner often reduces the amount of preparation required and helps prevent secondary damage to concrete surfaces, garage slabs, and adjacent structures.

Getting a Professional Evaluation

Determining whether an asphalt driveway, private road, or pipe stem can still be maintained or should be replaced starts with evaluating overall surface condition and repair history.

An experienced asphalt paving contractor can help identify which issues are cosmetic and which pose risks to safety, drainage, or nearby structures. Replacing asphalt at the right time—rather than continuing temporary repairs—often prevents further damage and delivers better long-term value.
