Cracksealing Shelton
Traditional crack sealing equipment are designed to only seal crack from 1/4 to 1 1/2 inches wide. That is why size matters.
When assessing a parking lot that needs crack sealant. You must understand the limitations of the material it self. Asphalt crack sealing products are designed to fill the crack and adhere to the walls of a crack preventing water from running down under the pavement and creating voids. When contractors apply the hot crack sealant, they usually leave a band on top of the crack so that during the freeze thaw cycle the material has some ability to expand and contract with the winter weather.
As for the application equipment, professional asphalt contractors will use crack sealing machines that have the ability to heat the asphalt crack sealing products to over 400 degrees. Crack sealing equipment is not cheap. That is a huge deterrent for small companies not fully committed to servicing the commercial industry. Remember when selecting a contractor to preform the services, application and equipment matter.
