Hot Rubber Crack Filling in Livonia, MI
An open crack in Livonia asphalt is a funnel. Rain and snowmelt run down it into the aggregate base, and in a climate with about 74 freeze-thaw days a year that water freezes and expands under the pavement again and again, lifting the edges and widening the gap a fraction each time. MDOT describes the same mechanism on state roads: moisture seeps in, freezes, pushes the pavement up, and leaves a void behind when the ground settles back. Filling cracks is cheap and unglamorous and it does more for the life of a driveway than any other single step, including sealing.
Hot-pour rubberized filler is heated in a kettle to a few hundred degrees, poured into the crack, and struck flush or slightly overbanded. It stays flexible through a Michigan winter, which matters because the crack is not a static gap. It opens in January and closes in July. A rigid filler, including the cold caulk in a tube from the hardware store, tears loose the first time the pavement moves and you are back to an open channel with a rubber strip beside it.
Preparation is the whole job again. Cracks get blown out with compressed air or a heat lance, and vegetation, dirt, and old failed filler have to come out or the new material bonds to debris instead of asphalt. Wider or badly spalled cracks sometimes get routed first, which cuts a clean reservoir with square walls so the filler has something to grip. On a Livonia driveway the classic candidates are the long transverse cracks that run across the drive at roughly even spacing and the joint where the drive meets the garage slab or the sidewalk.
Which cracks need filling and which can wait
Not every line on your driveway is a problem. What matters is width, depth, and whether water can get down it.
- Anything a nickel fits into, roughly a quarter inch or wider, should be filled before winter
- Transverse cracks running straight across the drive at fairly even spacing, the classic thermal pattern
- The joint where the asphalt meets the garage floor, apron, or sidewalk, which opens every year
- Long edge cracks a foot or so in from the side, usually where the base is unsupported and the shoulder has settled
- Any crack with grass or moss growing out of it, because roots hold moisture and widen the gap
Fine surface hairlines in a tight grid do not get individually filled. Those are oxidation cracking in the top of the mat and they get handled by [sealcoating](/driveway-sealcoating), which bridges them.
Hot pour, cold pour, or rout and seal
Three approaches, and the right one depends on how wide the crack is and how much it moves.
Hot-pour rubberized filler
The standard for driveways and lots in this climate. Stays flexible below freezing, bonds well to clean asphalt, and typically holds several winters.
Cold-pour pourable filler
Cheaper and needs no kettle, and reasonable for a handful of narrow cracks on a drive you plan to replace soon. It shrinks as it cures and generally does not last as long here.
Rout and seal
A saw or router cuts a clean square reservoir before filling. More expensive, and worth it on wide, spalled, or repeatedly failed cracks, and on commercial lots where the repair has to survive plow blades.
Do nothing
Only defensible if the pavement is scheduled for removal. Every winter an open crack goes unfilled in Livonia costs you base, not just surface.
If a crack has already been filled once and failed, ask about routing it rather than pouring more material over the old repair. The second failure usually happens for the same reason as the first.
Hot Rubber Crack Filling FAQs
When is the best time to fill cracks in Livonia?
Late spring through early fall, and ideally before the first hard freeze. NOAA's normals put the median first fall freeze at Detroit Metro on October 24 and the median last spring freeze on April 20, which brackets the working season. There is a second argument for doing it in cooler weather: cracks are at their widest when the pavement is cold and contracted, so filler placed in October sits in a fuller reservoir than filler placed in July. Either works. Filling before winter is what matters.
Is crack filling included in sealcoating?
Usually not. Most crews in this market price cracks separately by the linear foot, because a driveway with six feet of cracks and one with three hundred feet are very different amounts of material and kettle time. Some quote a package. When you compare two prices, check whether both include crack work before you decide one is cheaper, and ask which filler they use. Hot-pour rubberized and cold pourable are not the same product and do not last the same number of Livonia winters.
