Frequently Asked Questions
What is crack sealing and how does it work?
Crack sealing involves cleaning out cracks and filling them with a hot or cold rubberized sealant that flexes with temperature changes. This prevents water from seeping into the base and causing further damage. It’s a preventive maintenance step, typically done before sealcoating.
What’s the difference between crack sealing and crack filling?
Crack sealing uses flexible, rubberized material designed for active cracks that expand and contract with temperature ideal for climates with freeze-thaw cycles. Crack filling uses a stiffer material better suited to non-moving cracks. Most Northeast climates benefit more from sealing due to seasonal temperature swings.
How long does crack sealing last?
Properly applied crack sealant typically lasts [3–5 years], depending on crack size, movement, and traffic. It’s a maintenance step meant to be reapplied periodically as part of routine pavement care, rather than a one-time permanent fix.
Can crack sealing be done in cold weather?
Crack sealing generally requires dry conditions and moderate temperatures for proper adhesion, typically above [40°F]. Some hot-pour rubberized sealants can be applied in cooler conditions than sealcoating can, but ideal results still come from scheduling during the spring through fall paving season.
Is crack sealing a DIY-friendly project?
Small, isolated cracks can sometimes be addressed with store-bought filler, but professional crack sealing uses hot-applied rubberized materials and proper cleaning equipment for a longer-lasting bond. For larger areas or recurring cracking, professional assessment helps avoid missing signs of deeper base problems.
Why is it important to repair cracks quickly?
Water entering cracks can freeze, expand, and worsen damage especially in cold climates like New Hampshire leading to potholes and base failure. Addressing cracks early is far less expensive than repairing the larger structural damage that results from ignoring them over a winter season.
Should crack sealing be done before or after sealcoating?
Crack sealing should always be done before sealcoating. Sealing cracks first prevents water intrusion, and then sealcoating provides a uniform protective layer over the entire surface. Doing it in the reverse order leaves cracks vulnerable and can undermine the sealcoat’s effectiveness.
What causes asphalt to crack in the first place?
Common causes include age-related oxidation, freeze-thaw cycles, poor base preparation, heavy loads, tree root intrusion, and lack of regular maintenance like sealcoating. In colder climates, seasonal expansion and contraction from freezing temperatures is one of the leading contributors to new cracking.
