Getting a Commercial Lot Ready for Winter: Crack Sealing, Drainage and Salt Storage
September 11, 2026
By late September the sealing season in Anderson has effectively closed. What remains is the short list that decides how the lot comes through to spring.
The Hierarchy Does Not Change, Only the Time Left
The maintenance order on any asphalt surface is the same every year: fix drainage first, fill cracks annually, patch before winter, seal every two to three years, stripe last. What changes in the fall is how much of that list is still achievable.
Sealer needs pavement at roughly 50 degrees F and rising to bond and cure, plus about 24 dry hours afterward. Once that is no longer reliable, the last three items drop off and the first three become the whole job. That is not a compromise; drainage and cracks were always the items that mattered most structurally.
Why Drainage Comes Before Anything Else
A typical lot here is four inches of asphalt over six inches of stone, sitting on Crosby clay that holds a perched water table half a foot to two feet down through much of the year. That base is effectively a bathtub. Water that gets in does not drain away, it waits.
Water expands roughly nine percent when it freezes. A base already holding water, subjected to that expansion repeatedly, moves. The pavement above it cracks in response, and the crack admits more water. Nothing applied to the surface interrupts that cycle, which is why a clogged catch basin or a low corner that ponds is a more urgent item in October than any coating decision.
The Pre-Winter Checklist
A property manager's fall pass on an Anderson lot comes down to a short, specific list. Each item is here because a plow blade or a freeze will otherwise make it worse.
- Clear catch basins, curb drains and swales so meltwater leaves the lot instead of refreezing in it.
- Fill every crack wider than about a quarter inch, because each one is a pipe into a base that cannot drain.
- Patch raised edges, broken pavement at basin rims and soft spots in the drive lanes before a blade finds them.
- Mark curbs, islands and bollards so a plow driver working at night can see them.
- Site the salt and snow storage away from the low corner, and off any pavement that was patched this season.
Salt Storage Is a Pavement Decision, Not Just a Logistics One
Where the pile goes determines where the brine goes. A salt stockpile or a plow pile sitting on the lot sheds concentrated meltwater for weeks, and it runs downhill into whatever is below it. Put that above a patched area or a low corner and the season's repairs take the worst of it.
Anderson lots also receive brine from the road network from mid-November to mid-March, so the lot is already getting a dose that arrives on tires. Choosing pile locations that drain toward a basin rather than across the pavement is a free decision made in October that pays out in April.
What the Spring List Will Look Like
April is the month for inspection, because thawed ground finally shows standing water, soft spots and new cracks. September hides all three. That makes the spring walk the diagnostic one and the fall walk the protective one.
Late May or June is the realistic start for sealing in Anderson, which means any parking lot sealcoating deferred now is a two-season wait rather than a two-month one. Planning for that gap is easier than being surprised by it, and it is the reason asphalt patching is worth doing in the fall rather than holding everything for a single spring push.
Doing the Short List Properly Beats Doing a Long One Badly
The temptation in a compressed season is to squeeze in a coat that the weather does not really support. A sealer film is roughly the thickness of a business card. It cannot bridge a crack, stiffen a soft base or stop a crack being driven from below, and applied outside its temperature window it may not harden at all.
The better use of the remaining weeks is crack filling and drainage, which is also a commercial lot looked at before the first freeze rather than after. The Anderson pavement data page carries the local freeze and soil figures, and why Anderson driveways fail explains the bottom-up failure pattern this list is designed around.

Quick Answers
Is it too late to sealcoat a commercial lot in Anderson in October?
In most years the reliable window has already closed. Sealer needs pavement at roughly 50 degrees F and rising, plus about 24 dry hours after application. Once overnight temperatures stop supporting that, a coat applied anyway may never harden properly. Late May or June is the realistic restart, so fall effort is better spent on crack filling and drainage.
Which matters more before winter, crack filling or patching?
Drainage first, then cracks, then patching. Cracks are the active route for water into a base that on Crosby clay cannot drain, and water expanding about nine percent as it freezes is what widens them. Patching matters too, but mainly for anything a plow blade can catch and tear out.
Does where the snow pile sits really affect the pavement?
Yes. A pile sheds concentrated meltwater for weeks and it runs downhill. Sited above a patched area or a low corner that already ponds, it concentrates exactly the water the pre-winter pass was meant to remove. Placing piles so they drain toward a catch basin costs nothing and is decided before the first storm, not during it.
