A sunken apron is the section of a driveway, typically the part closest to the street or garage entrance, that has settled or sunk below its original level. This sinking often occurs due to issues like poor soil compaction, water erosion, or the natural settling of the ground over time. A sunken apron can create uneven surfaces, leading to water pooling, cracks, and potential damage to both the driveway and adjacent structures like a garage. It can also make driving in and out of the driveway more difficult and can be a tripping hazard. Promptly addressing a sunken apron is crucial to safeguarding your driveway from further problems.
Identifying the Problem
When the apron sinks, it creates a gap. This gap, between the driveway and the road, allows water to seep in. Water is the main culprit here. It erodes the base material beneath the apron. Over time, this erosion makes the problem worse.
Sunken aprons also create bumps. These bumps are annoying when driving in and out. For pedestrians, they become a tripping hazard. Early detection is key. Look for signs of water pooling, cracks, or visible gaps in the apron.
Causes of a Sunken Apron
Inadequate compaction of the base material is a frequent culprit behind the gradual sinking of a driveway apron, particularly close to a garage. This can have implications for both the overall driveway and the entrance to the garage. Additionally, the consistent movement of heavy vehicles, such as cars entering and exiting the garage, can further exacerbate this issue, leading to accelerated deterioration of the apron’s condition.
Water damage also contributes to a sunken apron. Water weakens the base material, especially near your garage if drainage is poor. Freeze-thaw cycles can aggravate the problem, as water freezes, expands, and creates voids under the apron and near the garage.
Steps to Repair a Sunken Apron
- Assessment: First, determine the extent of the damage, especially near the garage entrance or road. Measure the depth of the sinking and check for cracks in the surrounding area, including where the driveway meets the car garage.
- Preparation: Begin by removing the damaged section of the apron, focusing on the area leading to your garage. Clear out the old material to reach the base.
- Rebuild the Base: Use proper material to rebuild the base. Make sure to compact it thoroughly. A well-compacted base prevents future sinking, protecting both your driveway and garage foundation.
- Pour New Concrete: Mix and pour new concrete into the apron, ensuring it’s level with both the driveway and the garage entrance. Smoothing the surface helps with water runoff and ensures a seamless transition.
- Curing: Allow the concrete to cure properly. This process takes several days. Keep the area free from traffic, including vehicles entering the car garage, during this time.
Preventing Future Problems
Proper base material compaction is essential, especially near the residential garage. Regular inspections of the driveway and apron can help catch early signs of sinking, particularly where the driveway meets the car garage.
Good drainage is equally important. Ensure water flows away from the apron and the garage entrance to prevent water from weakening the base.
By following these steps, you can restore the integrity of your driveway. A well-maintained apron enhances the appearance and provides a smooth transition between the driveway, road, and car garage, extending the life of your driveway.
