Welcome To Crack Stix

Crack•Stix® is THE ONLY permanent solution for concrete (and blacktop) joint and crack repair. No longer do you need a crew to get professional results. Crack•Stix® carries a lifetime guarantee and meets or exceeds ASTM C920-11 Standard Specification for elastomeric sealants, Type S, T1 for pedestrians and vehicular traffic. It is paintable with Acrylic, latex or epoxy coatings.

Just like it’s blacktop version Crack•Stix® that has been in the marketplace since 1999, the gray version will protect your concrete, beautify it and prevent slip, trip and fall accidents (It will also adhere to faded blacktop for those of you that do not want the contrast of black crack filler to faded blacktop). The product contains NO VOC’s and is very easy to apply: Clean out the crack, pack the Crack•Stix® in the joint or crack and heat it. Traffic Ready in 20 minutes.

Crack•Stix® comes in two diameters: ½' (125ft) and ¼' (225ft) and is also now available in our NEW 500ft and 1000ft spools (both ½' and ¼') for contractors! Please visit our shop to learn more about the spools (they are only available on THIS website!) as well as our new CSX 1000 PRO Melt Torch (you can click HERE to view the PRO Melt Torch in action!). We ship throughout the US and worldwide.

Please take a look at a recent article from About.com: 'Crack Stix®: A Unique Concrete Joint Repair Product' or if you'd like to see a recent video we received from a customer working on his pool deck click here! Gray Crackstix also works as a GREAT binder for concrete pavers / paver blocks. It sets immediately and isn't weather sensitive (can be done year round - sorry Liquid Nails): Check out the video by clicking here!

It's EASY: Clean out crack, put in the Crackstix and melt. Even though we offer both 1/4' and 1/2' remember - you can either stretch them out to make them thinner or double them over to make them wider! For deep cracks just lay in some stone dust, sand or even closed cell backer rod first!

Why is it better than the tube based products? If the product sinks or loses bond you simply re-heat or put more in and re-heat. There is no need to scrape out.

Some Of Our Customers...

While the terms crack filling and crack sealing are often used interchangeably, there are differences between these methods of pavement crack repair. Understanding these differences will help you make the most cost-effective choice and long-lasting solution for crack treatment of your asphalt surfaces.

Crack sealing

Crack sealing is a method in which hot sealant is applied to working cracks to prevent water intrusion.

What are working cracks?

• Working cracks are horizontal and/or vertical movements in cracks greater than 0.1 inches.
• An example of working cracks is a transverse crack.

Understanding crack sealants

Crack sealants are rubberized and have the ability to seal the crack while staying flexible with the pavement’s movement. Beneficial for active cracks that continue to extend in size and severity over time, crack sealants stop water and debris from entering the crack, protecting the longevity of the pavement.

Crack filling

Crack filling is the placement of asphalt emulsion into non-working cracks to reduce water infiltration and to reinforce the adjacent pavement.

What are non-working cracks?

• Non-working cracks are horizontal and/or vertical movements in the crack less than 0.1 inches.
• Examples of non-working cracks include longitudinal, diagonal and alligator cracks.
• In contrast to crack sealing, crack filling treats pavement that doesn’t show significant movement.

7 types of cracks

Before you choose which method is best for treating your pavement cracks, it is critical to understand the types of cracks that can occur:

1. Transverse cracks

• The crack extends in a perpendicular fashion to the centerline or laydown direction of the pavement.
• Cause: thermal shifts and are the first to appear.

2. Longitudinal cracks

• Longitudinal cracks run parallel to the centerline or laydown direction of the pavement and appear later than transverse cracks.
• Cause: Poor lane join construction, pavement shrinkage, hardening of the asphalt and shifts in temperature.

3. Edge cracks

• Edge cracks develop between the edge of the pavement and concrete curbs.
• Cause: Seasonal thaw cycles that result in widening and deepening of the crack.

4. Seam cracks

• Seam cracks develop along joints of pavement.
• Cause: Poor paving procedures

5. Block cracks

• Block cracks develop in square pieces and are spaced between 4 to 12 feet. They often appear at the end of the pavement life.
• Cause: improper construction of base courses or lack of drainage.

6. Reflective cracks

• Cause: Changes in the movement of the sub-base, causing the surface material to crack.
• Correcting sub-base courses can help eliminate reflective cracks.

7. Alligator cracking

• Alligator cracking is a series of interconnecting cracks that are extensive, close together and resemble an alligator’s skin.
• Cause: Deterioration in the asphalt from repeated traffic loading.

Choosing the right method of crack repair

When deciding whether to fill or seal a crack, the best option is to speak to a professional. They will carefully evaluate the type of crack, expected movement of the pavement and whether it is a working or non-working crack. Transverse cracks are usually the first to appear in pavement surfaces, but other types of cracks can develop at the same time.

Crack filling: Often the best option for non-working cracks with moderate to no edge deterioration.

Best Rubberized Asphalt Crack Filler

Crack sealing: Often best option for cracks with limited edge deterioration.
