ABSTRACT:
A method and apparatus for manufacturing a crack repair product, and a method of repairing a crack using the product are disclosed. The material is made by heating and softening a bulk sample of direct-fire crack sealer material. The softened material is then extruded into a strand having a predetermined diameter. An anti-adherent material such as a polyethylene film is then applied to the extruded material, and the material is drawn along its length to reduce the diameter of the material to a desired diameter. In order to repair a crack, a length of the material is selected and has a diameter corresponding to the crack width. The material is packed into and near the top of the crack, and is then melted to permanently seal and repair the crack.
