Working in Onalaska
On a retail lot the cracks that matter are in the drive aisles and at the entrances off Highway 16, because that's where traffic pumps water down into the base. Around 26,000 vehicles a day go by on that corridor and a good share of them turn in somewhere. Wide cracks get routed so there's a clean face for the rubber to bond to, and hot pour stays flexible through a winter where cold pour pulls loose. Filling before the freeze is what keeps the next spring's repair list short.

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 Onalaska
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.
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 Onalaska
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.

This is Driftless country. The ice never came through, so there's no glacial drift, the bedrock sits near the surface, loess covers much of it, and the ground drains so freely that natural lakes are almost absent.
