This is from a recent job site in West Chest OH. There was a total of 72 feet of expansion joints, 12 feet of porch gaps, and another 19 feet of garage to driveway gaps. We removed any old debris and degraded expansion felt. We then proceeded with installation of backer rod and packing techniques to prepare the surface for caulking adhesion. Once sealed, the lines are then blended with a sifted sand mix.
