Filling cracks early is the cheapest way to stop North Dakota's freeze-thaw cycle from destroying your asphalt. Here is what crack sealing costs in the Bismarck area, why hot-pour sealant works, and when a crack means it is time to patch instead.
Asphalt crack filling in the Bismarck area typically runs about $1 to $3 per linear foot, with a minimum charge on small jobs. What moves the number:
Crack filling is almost always done right before sealcoating so the whole surface is protected at once. Request a quote and let us know roughly how much cracking you are seeing.
Every crack is a doorway for water. In Bismarck, water that reaches the gravel base beneath your asphalt freezes and expands in winter, then thaws — a cycle that repeats all season and slowly pries the pavement apart from underneath. A narrow crack you ignore this year becomes a wide one next year, then a pothole. Hot-pour rubberized sealant bonds to the crack walls and flexes with the asphalt as it expands and contracts, keeping water out year-round. It is the highest-return maintenance you can do on North Dakota pavement.
We clean each crack of dirt, vegetation, and loose debris, and rout or widen severely deteriorated cracks so the sealant can bond. Then hot-pour rubberized crack sealer is applied to fill the crack and form a slight overband at the surface. It sets quickly and can usually be driven on the same day. Filling cracks before sealcoating gives the best-looking, longest-lasting result. If cracks have widened into alligator patterns, that section needs patching instead.
About $1 to $3 per linear foot depending on width, depth, and total footage, with a minimum on small jobs.
It keeps water out of the base, stopping the freeze-thaw cycle that widens cracks into potholes.
Once cracks widen into alligator patterns or the asphalt crumbles, the area needs patching or resurfacing.
Usually the same day. Hot-pour sealant sets quickly once it cools.
