For extensive cracking, we use Flex-A-Fill from Koch Pavement Solutions. Flex-A-Fill is a rubberized, elastomeric joint sealant. This means that the product will allow for expansion and contraction of the asphalt and still return to its original shape. The product is heated above 350 degrees and poured into the joints or cracks. For driveways with limited cracking, we use SealMaster commercial grade joint sealant.
