What a Crack Filling and Sealing Job Looks Like in Mondovi

Main Street is the commercial core, running along the highway through town, with the banks, the pharmacy, the grocery and the clinic strung along it or one street off.

The larger story is freight. A truckload carrier is headquartered in Mondovi and employs several hundred people here, which means yard and lot surface built for tractor units rather than cars. That's a different specification from anything else in a town this size: heavier section, wider turning radii, and failure that shows up as rutting long before it shows up as a hole.

Crack Filling and Sealing specifically in Mondovi

On a slope an open crack isn't just a crack, it's an inlet. Water enters uphill and travels through the base rather than sitting where it landed, so the damage turns up somewhere below where the crack is. That's why crack filling buys more time here than it does on flat ground, and why the crack that looks harmless at the top of a Mondovi drive is usually the one doing the work at the bottom.

The Driveways and Lots in Mondovi

Mondovi sits in Buffalo County on the Buffalo River, where Highways 10 and 37 meet, in valley ground rather than on the flat. It's the westernmost city we hold a page for and the ground here's Driftless: cut valleys, real grade, and drives that run downhill more often than they run level.

Roughly half of Mondovi's housing predates 1960, and about a fifth predates 1940. Only a small share has been built since 2000.

On a driveway, age plus grade is the combination that matters here. Water running down a sloped drive concentrates at the bottom, and on a sixty-year-old surface that's where the failure starts. The apron at the street sees it first.

Mondovi

We work the whole village rather than a named handful of neighborhoods.

Standard 48-inch frost depth. Valley position means cold air settles here at night, so an early or late-season pour has a narrower daily window than it does on the flat.

Hot rubber vs. cold pour

The stuff in a jug at the hardware store is cold pour. It goes in as a liquid, dries, shrinks, and sits in the crack like a rubber band laid in a trench. It's not bonded to anything. The first hard freeze pulls the crack open, the filler has nothing holding it to the walls, and it lifts out in a strip. Most people have seen this happen and assumed it was a bad batch. Hot-applied rubber goes in at around 400 degrees. At that temperature it's thin enough to run down into the crack instead of bridging it, and hot enough to melt into the asphalt faces on either side. When it cools it has bonded to the walls of the crack, so when the crack moves, the filler moves with it.

Cold pour

The jug from the hardware store, and what a cheap quote uses

  • Sits in the crack rather than bonding to it
  • Shrinks as it cures, leaving a channel down the middle
  • Pulls out in strips after the first hard winter
  • Cheap enough that it gets redone every year, which isn't cheap

Hot-applied rubber

What comes off our kettle

  • Flows to the bottom of the crack at 400 degrees
  • Melts into the asphalt faces and bonds to both walls
  • Stays flexible, so it moves when the crack moves
  • Holds for years, not for one season

This is the one place where the cheaper option isn't a smaller version of the right one. It's a different product doing a different thing.

What Decides the Price in Mondovi

Priced by the foot of crack, not by the area of the surface, because that's what actually drives the work. Usually done as part of a sealcoating job, where it costs less than it would on its own.

With a sealcoat job

Driveway

Measured on site

  • Most driveways need some, and it's included up to a point
  • Heavy cracking is quoted separately and said up front

Crack filling alone

Driveway, no sealcoat

Measured on site

  • Worth doing on its own if the surface is otherwise sound

Commercial lot

Per linear foot

Measured on site

  • Depends on crack width, depth and how much routing it needs
  • Most lots are quoted as a lump sum after a walk

Cracks wider than about an inch and a half, or ones that have broken into a network, are past filling. Those get cut out and patched rather than filled with something that will not hold.

How the Work Goes in Mondovi

Done before sealer, always: sealer can't bridge an open crack.

Clean the crack out

Blown out with compressed air, vegetation and old failed filler removed. Rubber won't bond to dirt any more than sealer will.

Rout the wide ones

Wide or heavily worked cracks get cut to a consistent reservoir so the filler has a proper shape to sit in. Not every crack needs it; the ones that do are the ones that have already failed once.

Fill hot

Direct-fire kettle, rubber at 400 degrees, wanded into the crack until it's full from the bottom up rather than skinned over at the top.

Squeegee and let it set

Struck off flush or slightly banded over, depending on the surface. Sets hard enough to drive on in under an hour in most conditions.

Questions We Get in Mondovi

What Mondovi calls us about, answered straight.

More questions answered
Someone sealed our sloped drive and it ran and pooled. What went wrong?
Too heavy a coat on a grade. Sealer that goes on thick runs downhill before it cures and gathers at the apron, which leaves the top thin and the bottom shiny and soft. On Mondovi's slopes it's the single most common way a seal job looks wrong within a month. Worked properly, a slope takes the same material, applied differently.
Our yard is used by tractor units. Is that the same job as a parking lot?
No, and it's worth saying so up front. A yard that takes loaded trailers needs a heavier section and wider turning room, and it fails as rutting in a repeated wheel path long before it fails as a hole. By the time the rutting shows, the base underneath has usually moved too, so those are full-depth repairs rather than surface ones.
Does the valley position change when you can work here?
It narrows the daily window rather than the season. Cold air settles in the valley overnight, so an early-spring or late-fall job here has fewer usable hours in the day than the same date would on the flat. It doesn't rule the work out. It does mean the date is worth settling early rather than assuming.
How much does crack filling cost?
It is priced by the linear foot of crack rather than by the size of the surface, so a big driveway with four cracks costs less than a small one that has opened up all over. Width matters too: anything wide enough to need routing out first takes longer. On a driveway it is usually included up to a point when it is done with a sealcoat rather than billed on its own.
Why does the temperature of the crack filler matter?
At 400 degrees the rubber is thin enough to reach the bottom of the crack and hot enough to melt into the asphalt on both sides, so it bonds. Cold pour filler can't do either, which is why it lifts out in strips after a winter.
Should I fill cracks before sealcoating or after?
Before, always. Sealer is a thin wear layer and it can't bridge an open crack. Sealing over one changes its color and nothing else, and the crack reappears through the new surface within weeks.
Is there a crack too big to fill?
Yes. Past about an inch and a half, or once cracking has broken into a network of squares, filling won't hold because the surface around it is moving independently. Those areas get cut out and patched instead.
When is the best time of year for crack filling?
Spring or early fall in Mondovi and the surrounding area is ideal, because cracks are at a middling width. In high summer they're at their tightest and in deep winter they're at their widest, and filling at either extreme means the filler is working against the movement rather than with it.
