Did your crack sealant make it through the winter?Last fall, many pavement owners spent good money fixing pavement cracks, but as the snow melted many failed fixes were revealed.
But why did your crack sealant fail so quickly in the first place?
In most cases, the technique used to fill the cracks was substandard.
(Common) Blow & Go – (Not recommended):
Quick and cheap but least effective. Debris / dirt is blown and cracks filled leaving most of the sealant on top – vulnerable to being pulled out and scraped off – leaving your pavement further exposed to the elements, traffic and plows, and pedestrians during everyday use. And, once moisture follows down through the cracks and enters a pavement’s base and support structure, the rate of deterioration and damage and cost to repair will accelerate significantly unless you act quickly.
In addition, the sealant that does make it down into the crack has gritty, rough, unprepared surfaces which do not promote optimum bonding surfaces. Either way, sealant will need fixed a lot sooner than you think!
VS
Rout & Flush Pour – (We recommend):
Quality sealant (Hot applied ASTM 3405 rubberized sealant; proven superior bonding properties, high resiliency – up to 300%, and great cold weather performance) is carefully placed into the routed, dried and prepared crack, filling up from the bottom, until flush with the surface. Voids and bubbles that can shorten the life of the crack seal are eliminated while also preventing most surface damage. This technique also yields and longest “like new” look and attractive appearance.
OR
Rout & Overband – (We recommend for failed repairs):
Effective for crack sealing previously sealed cracks that cannot be routed. Sealant is carefully placed into the dried and prepared crack, filling up from the bottom, and squeegeeing the sealant flush with the surface. This minimizes most damage from traffic, plows, and pedestrians but is less attractive than the Rout & Flush Pour technique.
For best, longer lasting results choose a trusted / knowledgeable expert installer!
It may look like a budget-saver, but as the old adage goes, “You get what you pay for.” You can risk hiring cheaper contractors but if they are not specifically trained in crack sealing, you will have to repeat the process again sooner, wasting your valuable time and money. Choosing a trusted/knowledgeable installer who will use quality products and the right equipment is key to to the long-term performance of any crack seal. We utilize state-of-the-art double jacketed melters designed to safely melt sealant, gently agitate, and then pump it through insulated hoses and specially designed applicators into cracks. We also equip our machines with self contained compressors to blow out oil free compressed air to better prepare cracks for sealant. When properly installed, hot applied crack sealants will last for years to come, protecting your pavement investment. Crack sealing is just one of several integral components in an overall preservation strategy.
