Pavement Cracks and Joints
Pavement cracks and joints are not the same. Cracks are caused by deterioration of the pavement. Obviously, pavement is best when it is first constructed. As sunlight oxidizes the pavement and seasonal temperature changes expand and contract the pavement, cracks form. Water, impurities, and debris infiltrate the cracks and continue to degrade the pavement and put the pavement’s subbase at risk.
Joints, in contrast to cracks, are not developed by deterioration but instead are built by design. Pavements are known to crack as they age, therefore joints are created when the pavement is constructed to control where cracking may occur.
Crafco focuses on quality and long-term performance and therefore manufactures products that have a significant service life like hot-applied asphaltic-based crack sealant for asphalt and cold-applied silicone joint sealant that have demonstrated in independent studies to provide the longest service life available.
There are cold-applied crack sealants sold by other manufacturers that may satisfy a short-term need in the marketplace. However, independent studies using cold-applied crack sealants have consistently proven to fail in less than a calendar year and are not manufactured by Crafco.

Hot-Applied Crack Sealant / Cold-Applied Silicone
Crafco Pavement Preservation Sealants are formulated to perform in a wide range of climatic conditions. All sealant specifications meet and exceed ASTM, Federal and State recommendations. Crafco is the only company that manufacturers pavement preservation sealants and the specialized equipment to apply them. They all work together to provide you the confidence that you are receiving the highest quality, innovation and value available.
PLEXI-melt™
Crafco’s PLEXI-melt is an innovative high strength, low density, protective packaging used to contain Crafco hot-applied sealants and mastics that quickly and thoroughly melts without affecting product installation characteristics or specification performance. PLEXI-melt packaged material is much easier to handle as blocks are dropped directly into the melter eliminating waste and empty boxes. PLEXI-melt block design melts much faster than conventional sealant block configurations, is both sun/water resistant and can be stored up to one year outdoors. US Patent Nos. 9,919,854; 10,220,993 | Chinese Patent No. ZL201210364578.6 | Hong Kong Patent No. HK1183852
Features and Benefits:
- PLEXI-melt eliminates need for traditional cardboard boxes!
- Saves Money! The need for an extra crew member is eliminated!
- Shape of PLEXI-melt block melts 58% faster than traditional boxed mastic/sealant material
- Easy to handle! Simply add PLEXI-melt block directly into the melter
- Fast melting packaging is made from an extremely strong yet durable material
- Does NOT affect mastic/sealant specification
- Promotes Safety. Each PLEXI-melt package is labeled with OSHA and GHS requirements

Hot-Applied Crack Sealants
Continuously proven to be the longest-lasting crack sealants on the market, the 100+ variations of crack sealants are formulated to perform in specific climates, elevations, slopes, and traffic conditions. In the most comprehensive pavement surface study ever conducted, Crafco hot-applied crack sealant for asphalt demonstrated more than seven years of sealant service life in asphalt pavement, the longest service life, while ~50% of non-Crafco sealants tested “failed” the study. All sealants are not the same. In the same study Crafco sealant demonstrated the lowest average annual cost per linear meter of crack.
In a separate study, Crafco hot-applied crack sealant for asphalt demonstrated more than 21 years of sealant service life in concrete pavement, the longest ever recorded and published.
You can be sure that there is a crack sealant engineered to be the best solution for your individual pavement preservation needs.
Crafco hot-applied asphalt crack sealants are available in our new, innovative, meltable PLEXI-melt™ packaging.
Hot-Applied Parking Lot Sealants
Parking Lot pavements are subject to slow moving vehicle traffic and foot traffic. These areas include but are not limited to: parking lots, parking garages, driveways, collector and residential streets, crosswalks, walkways and recreation areas. Due to the nature of these types of pavements, special care should be taken when sealing cracks in these areas because they encounter different types of traffic than highways and high traffic volume roads. Crafco Parking Lot Sealant is specifically formulated for these areas.
Hot-Applied Loop Detector Sealants
Crafco Loop Detector Sealant is a single component, hot melt, rubberized asphalt material formulated to be a stiff, yet flexible, sealant which is ideally suited for sealing traffic loop detector cuts. Crafco Loop Detector Sealant is a thin, free flowing fluid which pours easily and penetrates narrow traffic loop detector cuts.
