Cleaning and filling of blacktop or Portland concrete pavement cracks and joints. Hot-applied products are federally specified and approved and are made of high quality, rubberized materials. The sealant in the crack forms a resilient and adhesive compound that will seal cracks and joints from the infiltration of damaging water. Use of the correct material prevents tracking by shoes or vehicles and lasts longer because it flexes with changing weather conditions. Preparation of the cracks may include dirt and vegetation removal, compressed air cleaning, heat lancing to dry the crack or routing of the crack by machine.
