Sealing cracks can be a profitable venture for contractors. This article discusses the equipment and methods used in crack sealing, and some of the challenges that contractors may face in educating customers on the value of sealing cracks. Although smaller contractors may choose to clean and dry cracks with a backpack blower and then use a basic melter and pour pot to fill in cracks, larger contractors can employ a melter/applicator with a dedicated air compressor to clean and dry cracks and a pump/hose configuration to apply the sealant. In order for a crack sealing operation to be successful, contractors must demonstrate the cost-efficiency of sealing cracks compared to putting down an overlay.
