Crack sealing is an essential component of your Pavement Management Program
Property managers and owners need to be aware that not all crack sealing services are the same. Crack sealing can be divided into three different types:
- Crack Filling: Crack filling involves topical sealing of pavement cracks without any type of crack preparation. This is typically the least effective of the crack sealing services, with the highest failure rate—it likely won’t survive its first winter.
- Blow and Fill: Blow and fill involves blowing out debris from cracks with backpack blowers or compressed air, then topical sealing of the pavement cracks. This has a marginally better life expectancy than simple crack filling, but is still subject to high failure rates.
- Rout and Seal Crack Sealing: Suitable cracks are routed with special pavement routing equipment to a width of 3/4″ wide and 1/2″–3/4″ deep. This process allows for a reservoir of rubberized crack sealer that facilitates expansion and contraction of the crack both horizontally and vertically. While cone filling of the rout is the standard process of installing the sealant, our crack sealing services use the superior method of overbanding, wherein the crack is overfilled and the sealant spreads onto the pavement around the crack on approximately 3/4″ of either side of the rout. This rout and sealing method, combined with the overbanding method, produces a crack-sealed joint with an extremely low failure rate and a serviceable life of between five and 10 years.
Preserving your pavement for the long run is our goal. That is why we will only offer you crack sealing services that employ the rout and seal method, overbanding the sealant for long-lasting results. While not the cheapest of crack sealing services, it is definitely the best value.
