The Most Cost-Effective Way to Extend Pavement Life in the Twin Cities Metro
Crack filling is one of the highest-return maintenance investments a property owner can make. A crack that costs a few cents per linear foot to fill today can cost hundreds — or thousands — of dollars to repair once water infiltrates the base, freezes, expands, and turns that small crack into a pothole or a failed section of pavement. In the Twin Cities Metro, where freeze-thaw cycles put asphalt through some of the most punishing conditions in the country, crack filling isn’t optional maintenance — it’s the most practical thing you can do to protect a pavement investment that costs tens of thousands of dollars to replace.
Czars of Tar, Inc. has been providing professional crack filling services to commercial and residential properties across the Twin Cities since 1991. Operating continuously for more than 30 years from our Ham Lake, MN base, we’ve filled millions of linear feet of asphalt cracks for property managers, HOAs, retail centers, and homeowners who understand that a small investment today prevents a large expense tomorrow.
Common Crack Problems That Require Filling
- Transverse Cracks — Cracks that run perpendicular to the direction of traffic or the pavement’s long axis. Often caused by thermal expansion and contraction, and very common in Minnesota’s climate. These are ideal candidates for crack filling before water and ice widen them.
- Longitudinal Cracks — Cracks that run parallel to the direction of traffic. Can indicate pavement fatigue, joint failure, or edge movement. Filling these early prevents them from widening into larger surface failures.
- Edge Cracks — Cracks that follow the edge of a pavement section, often where asphalt meets a curb, shoulder, or unpaved area. Water gets in from the edge and weakens the base — early filling is critical at these locations.
- Reflection Cracks — Cracks that appear in an overlay or resurfaced pavement, reflecting the crack pattern from the layer below. Filling these prevents water from reaching the base through the overlay.
- Block Cracking — A pattern of interconnected cracks dividing the surface into large blocks, typically caused by asphalt oxidation and hardening. Early filling helps stabilize sections before they progress to alligator cracking.
- Random Surface Cracking — Irregular, non-patterned cracks appearing across aging asphalt surfaces. Addressing these through a comprehensive crack filling program significantly extends pavement life before resurfacing or replacement becomes necessary.
Our Crack Filling Solution
- Pavement Assessment and Scope — We evaluate crack type, width, depth, and extent to determine the appropriate filling method and material. Your written estimate covers the full scope with no hidden additions after the work begins.
- Crack Cleaning and Preparation — Cracks are cleaned of vegetation, dirt, sand, and debris using compressed air or routing equipment before any material is applied. Clean cracks are essential — filler bonded to dirt and debris won’t hold.
- Routing Wide Cracks (When Required) — Wider or irregular cracks are routed to a uniform width and depth before filling. Routing creates a consistent reservoir for the fill material and improves long-term adhesion and flexibility.
- Hot-Applied Crack Filler Application — We use hot-applied, rubberized asphalt crack filler — the professional-grade standard for crack filling on commercial properties. This material remains flexible across a wide temperature range, expanding and contracting with the pavement through Minnesota’s seasonal extremes rather than cracking like cold-applied fillers.
- Overfill and Squeegee Finishing — Material is applied slightly proud of the surface and squeegeed flush. This technique ensures the crack is fully filled and sealed at surface level without leaving a raised ridge that catches vehicle tires or snowplow blades.
- Cure Time and Surface Protection — Hot-applied filler cures rapidly but needs appropriate time before heavy traffic or sealcoating. We provide return-to-service guidance and sealcoating sequencing recommendations as part of the completed project.
What Makes Czars of Tar Crack Filling Last
- Hot-Applied Rubberized Filler — Not Bottled Cold Filler — Professional crack filling uses hot-applied rubberized asphalt material that flows into the crack completely and remains flexible across temperature extremes. Cold-applied crack fillers from hardware stores harden, lose flexibility, and fail in Minnesota winters. We use the professional-grade product that actually works.
- Crack Cleaning Before Filling — Every Time — Filler applied over dirt, vegetation, or debris bonds to the contamination, not to the asphalt walls. Our crews clean every crack before filling — a step that’s frequently skipped and directly responsible for early filler failure.
- Routing Wide or Irregular Cracks — Cracks wider than approximately 3/4 inch benefit from routing to create a consistent reservoir geometry that produces better filler adhesion and longer-lasting results. We include routing when the crack width and condition warrant it.
- Proper Sequencing with Sealcoating — Crack filling and sealcoating work together as a system. Filling is always done first, before sealcoating, and the filler must be fully cured before the seal coat is applied. Correct sequencing is part of how we plan and price maintenance programs.

Crack Filling FAQs
How long does crack filling last?
Hot-applied rubberized crack filler typically remains effective for 3–5 years in Minnesota’s climate, depending on traffic, pavement condition, and winter severity. Cracks in actively moving or structurally compromised pavement may require more frequent attention. Filling cracks on a consistent schedule — typically combined with sealcoating every 3–5 years — is the most cost-effective long-term maintenance strategy.
Can cracks be too wide to fill?
Cracks wider than approximately 1 inch may be beyond the effective range of crack filling and could indicate base movement or structural failure that requires repair rather than filling. During our assessment, we identify any cracks that are too wide or active for filling and recommend the appropriate next step.
Should crack filling be done before or after sealcoating?
Always before sealcoating. Crack filling addresses the structural openings in the pavement surface, while sealcoating provides a protective coating over the entire surface. Filling first, then sealing, produces the best overall result. Sealcoating over unfilled cracks doesn’t seal them — it just spans them temporarily before breaking through.
How do I know which cracks need filling vs. which indicate a larger problem?
Isolated transverse cracks, longitudinal cracks, and edge cracks with firm edges are generally good filling candidates. Alligator cracking (web-like interconnected patterns over an area) typically indicates base failure and requires repair, not filling. We assess every property’s crack patterns during the site visit and give you a clear picture of what’s fillable and what isn’t.
Can you fill cracks on both parking lots and residential driveways?
Yes. Czars of Tar provides crack filling for commercial parking lots, HOA properties, retail centers, and residential driveways across the Twin Cities Metro. The same professional-grade methods and materials apply to both — we don’t use a different standard for smaller projects.
