The most common version of this problem is some form of “I keep putting shell on it and it keeps washing out.” That's not a shell problem. That's water going somewhere it shouldn't, and no amount of surface material will out-argue it.
Read the symptom
What's failing, and where, usually tells you the cause before anyone digs anything.
Ruts in the wheel paths
Material is moving sideways under load. Either it was never compacted, it was placed over organics that are still down there, or the subgrade is soft. Common on drives built by spreading material on bare ground.
Washboard ripples
Loose, dry surface with no crown. Self-reinforcing once it starts. Fixed by reworking material with binding fines and re-establishing shape — not by blading it flat.
A channel running down the middle or along one edge
Water is using your driveway as its drainage route. Means the crown is wrong or absent, and the swale is missing, silted or never cut. This is the classic east-county failure.
Standing water that stays for days
Nowhere for it to go. Sometimes a flat spot, more often a swale that's filled in or a culvert that's packed. Where a restrictive subsoil layer or a high seasonal water table slows downward drainage, it won't percolate away either — so it sits there softening the base.
A dip directly over the culvert
Settlement from poor compaction when the pipe was installed. See the FAQ below — this one has a specific fix.
Soft spots that never firm up
Usually buried organic material — a stump, a root ball, old fill — decomposing underneath. It has to come out. Material added on top just sinks.
Erosion at the road end
Often the apron or the culvert ends. If mitered ends and concrete slopes were never built, the banks erode and the drive edge follows.
The pattern worth noticing
What repair actually involves
Depending on the diagnosis, one or more of:
- Regrading. Re-cutting the crown so water leaves the surface instead of running along it.
- Swale cutting or cleaning. Re-establishing the channel that gives water somewhere to be.
- Culvert clearing or replacement. A pipe that silts shut annually usually has a grade problem — see culvert installation.
- Undercutting soft spots. Removing buried organics or saturated material and replacing with compactable fill.
- Base repair. Reworking and recompacting the structural layer rather than covering it.
- Resurfacing. New shell or limerock, placed in lifts and compacted — last, once the reason is fixed.
When repair isn't worth it
A straight answer here matters more than a sale. A rebuild is usually the better spend when the subgrade is soft along most of the run, when the drive was built over unstripped ground and is failing everywhere rather than somewhere, or when you've already paid for two or three rounds of material in the last few years.
Three repairs across four seasons usually adds up to more than building it right once. It rarely feels that way at the time, because each individual load of shell is cheap.

Driveway Repair Questions
Can't I just add another load of shell?+
Sometimes — if the base is sound and the surface just wore thin, a refresh is genuinely the right answer, and a straight contractor will say so.
But if the same section fails over and over, material is treating a symptom. New shell on a soft base, or on a drive with nowhere to send water, does exactly what the last load did — usually inside one wet season.
Do I need a permit to repair my driveway?+
Routine maintenance, no. But the county's code covers driveways that are improved or enlarged, not just newly built — so widening the drive or replacing the culvert does require the access and drainage permit. Grading out ruts and topping up material generally doesn't. If your repair touches the right-of-way, check the permit guide.
What causes washboard ripples?+
Loose dry material on a drive with no real crown. Tires bounce, each bounce moves a little material, and the pattern feeds itself. Blading it flat is temporary — the conditions that made it are still there. A lasting fix reworks the material, adds fines so it binds, and re-establishes the crown.
There's a dip right where the culvert is. What's that?+
Almost always compaction — the fill around the pipe was never consolidated when it went in. It settles, the surface can't bridge the void, and you get a depression right over the culvert that gets deeper every year. Filling it from the top buys a few months. The real repair is excavating, re-bedding and compacting properly around the pipe.
Is it cheaper to repair or rebuild?+
Repair wins when the base is intact and the problem is either surface wear or one identifiable cause — a blocked pipe, a silted swale, a single soft spot. Rebuilding wins when the subgrade is soft along most of the run, because three repairs across four years costs more than doing it once correctly. Any contractor worth hiring will tell you which one you're looking at.
