Key Takeaways

• Address driveway sinking promptly to prevent safety risks and further damage.
• Preparation and proper drainage are critical for a long-term driveway repair solution.
• Evaluate whether DIY or professional repair is appropriate for your situation to ensure cost-effective and durable repair.

Diagnosing the Problem

When your driveway begins to sink, it’s critical to assess the situation carefully to address the underlying issues effectively. Early diagnosis can save you from more extensive and expensive repairs down the line.

Identifying Common Signs of Sinking

A sinking driveway is often accompanied by easily noticeable indicators. Cracks and depressions in the surface are clear signs that there’s an issue below. If you observe portions of your driveway appearing lower than the surrounding area or find voids along the edges or beneath the surface, these are strong indications that sinking is taking place.

Understanding Soil Erosion and Compaction

Soil erosion and improper compaction are chief culprits behind a sinking driveway. Erosion occurs when water washes away the supporting soil, creating voids. On the other hand, if the soil beneath your driveway wasn’t compacted sufficiently during construction, it can gradually compress and cause the surface to sink. It is essential to determine if soil erosion or compaction issues are causing the problem to address it appropriately.

Preparation for Repair

Before you start the repair process for a sinking driveway, it’s essential to have the right materials at hand and ensure the work area is safe. Whether you’re dealing with concrete, asphalt, or gravel, appropriate preparation can help achieve a durable result.
