At Empire Parking Lot Services we understand how important Prep work is when it comes to a successful seal coating project. One aspect of seal coating preparation is the filling of cracks. Crack filling is a important tool in getting the most life span out of already cracked and failing asphalt.  One fact about cracks in asphalt is that once they’re there they are not going to be fixed easily.  Once a crack is allowed to develop in your parking lot its pretty much a problem that has to be dealt with until that asphalt is removed completely and replaced with new asphalt. Here are some important fact to remember.

• The purposes and functions of crack sealing and crack filling must be clearly understood so that the most cost effective and long-lasting treatment is applied.

• Crack Sealing- The placement of specialized materials either above or into working cracks using unique configurations to prevent the intrusion of water and debris into the crack.

• Crack Filling- The placement of materials into nonworking cracks to substantially reduce infiltration of water and to reinforce the adjacent pavement.

Working refers to horizontal and/or vertical crack movements greater than or equal to 0.1 in (2.5 mm); nonworking refers to movements less than 0.1 (2.5 mm).  It is assumed that where cracks are exhibiting significant vertical deflections, the appropriate repair strategy will be sought.  Hence, for cracks with limited vertical movement, horizontal movement becomes the critical factor in determining the need for, and planning for, a crack treatment operation.  Let on our estimators look at your parking lot to determine what type of cracks are on your lot.  Once treated appropriately your parking lot can be treated and then seal coating can be done for a quality finish.

As the above definitions indicate, the objectives of crack sealing is significantly more difficult to accomplish than those of crack filling. Sealing requires considerably more forethought, greater costs, an use of specially formulated materials and more sophisticated equipment.  Empire knows how to handle these issues and help you to understand the difference.
