Direct answer: Driveway settlement near the garage usually means the base under that section has washed out, compacted poorly, or softened from repeated water runoff. Start by checking whether you have a small edge drop you can patch temporarily, or a slab section that has actually sunk and opened a gap at the garage floor.
Most likely: The most common cause is water working along the garage edge or driveway joint, then carrying fines out from under the driveway until that section drops.
Look at the shape of the drop before you decide anything. A shallow birdbath or minor lip can sometimes be managed short-term. A slab corner or full section that has sunk near the garage is different, especially if the gap is growing, the garage apron is cracking, or water now runs toward the garage. Reality check: once concrete or asphalt loses support underneath, surface-only products are usually temporary at best. Common wrong move: packing loose sand into the gap and calling it fixed.
Don’t start with: Do not start by smearing crack filler over the joint or coating the whole driveway. That hides the clue you need and does not fix a settled base.
A shallow low spot near the garage that catches water, but the surface is mostly intact and still feels solid underfoot.
Start here: Start with drainage and depth checks to see whether this is a temporary patch situation or early settlement.
A slab corner or a strip of driveway sits lower than the garage floor, often with a visible lip or widened joint.
Start here: Check for movement, voids, and runoff patterns. This is the classic settled-base pattern.
You see diagonal or stepped cracks near the garage opening, sometimes with one side sitting lower than the other.
Start here: Treat this as structural movement in the driveway section, not just a sealing job.
Rainwater or meltwater now heads back toward the garage instead of away from it, and the settled area stays wet longer.
Start here: Check downspouts, grading, and buried drainage first because ongoing water is what keeps the settlement growing.
This is the most common pattern when settlement is tight to the garage. Roof runoff, poor grading, or a leaking downspout extension can carry support material out from under the driveway.
Quick check: Run water from a hose uphill of the area or watch the next rain. If water tracks along the joint or disappears under the slab edge, base washout is likely.
If the driveway was poured or paved over fill that was not compacted well, the section can settle over time even without a dramatic crack at first.
Quick check: Look for a broad, even drop with fewer signs of erosion. Older settlement that has stabilized often looks like this.
Water gets under the edge, freezes, shifts the support, then leaves a bigger void when it thaws. This is common where snowmelt sits near the garage door.
Quick check: Ask whether the drop got noticeably worse after winter or after repeated icing and thawing.
If the area is soft, crumbling, or heavily cracked, the issue may not be simple settlement at the garage edge. Asphalt base failure or broken concrete sections can mimic settlement.
Quick check: Probe the area with your foot and look for loose aggregate, pumping water, or alligator-style cracking spreading away from the garage.
You need to separate a shallow low spot from a truly sunken section. That tells you whether a patch is only a stopgap or whether the slab has lost support underneath.
Next move: If the dip is shallow, localized, and the surface still feels solid, you may be able to manage it short-term while you correct drainage. If a slab corner, strip, or full section is clearly lower than the garage floor, treat it as settled support under the driveway.
What to conclude: A broad settled section points to lost or compacted base. A tiny surface dip without movement is less serious, but still worth watching if it holds water.
Settlement near a garage almost always has a water story behind it. If you do not stop the water, the repair will not last.
Next move: If you find obvious runoff feeding the area, correct that first and then reassess the driveway after a few wet cycles. If no clear water source shows up, the driveway may be settling from old poor compaction or a hidden void that needs a pro to evaluate.
What to conclude: Active water movement means the settlement is probably still progressing. Dry, older-looking settlement may be more stable, but it still needs the right repair path.
Homeowners waste time when they treat a sunken slab like a surface blemish. This is where you choose the right level of repair.
Next move: If it is only a shallow low spot and the base still feels firm, a driveway patch can buy time after drainage is corrected. If the section is truly sunken or unsupported, the durable fix is usually slab lifting for concrete or removal and base repair for failed asphalt.
A temporary repair is reasonable when the drop is small, stable, and you have already dealt with the water source. The goal is to reduce ponding and trip risk, not pretend the slab was lifted.
Next move: If water sheds better and the patch stays put, you have bought time while you monitor for continued movement. If the patch cracks, sinks, or breaks loose quickly, the driveway section needs support repair, lifting, or replacement rather than more topping.
Once you know whether the problem is active water, shallow settlement, or a dropped section, the next move should be clear. Waiting through another wet season usually makes the repair bigger.
A good result: You end up with a repair that matches the actual failure instead of paying twice for temporary fixes.
If not: If you still cannot tell whether the driveway or the supporting soil is the main problem, bring in a driveway contractor or concrete lifting specialist for an on-site evaluation.
What to conclude: The right finish depends on whether the surface is merely low or the support underneath is gone. That distinction is the whole job.

Not always. Most of the time the driveway section has lost support from washout, poor compaction, or freeze-thaw movement. If the garage slab, wall, or foundation is also cracking or shifting, then you need a closer structural look.
Only if the gap is stable and small, and even then that is not the main fix for settlement. If the driveway section has dropped, filling the gap does not restore support underneath or correct drainage.
Usually not if the section has actually settled. Patching is a reasonable short-term move for a shallow, stable depression after you correct the water source. It is not a permanent fix for a sunken slab or failed asphalt base.
It is worth considering when a concrete section is intact but has clearly sunk and the problem is loss of support underneath. If the slab is badly broken, crumbling, or tied up with larger apron damage, replacement may make more sense.
Asphalt near a garage can settle too, but if it feels soft, pumps moisture, or shows widespread breakup, the repair is usually cut-out and base repair rather than topping over it. A surface patch only lasts when the base is still sound.
Yes. Water that gets under the driveway edge can freeze, expand, and leave a bigger void when it thaws. That is why a small low spot near the garage often turns into a bigger drop after one or two winters.
