Although either hot-pour or cold-pour crack sealers can be used, the two products have very different qualities and application methods. The results will also differ, with cold-pour fillers having the shorter life. As cold-pour crack sealants seldom survive a cold winter and do not hold up as well to traffic, they are used sparingly — most often for residential driveways. For roadways and parking lots, the hot-pour products are virtually always chosen. Asphalt crack repair in Atlanta offers several options…let’s talk about both of them.
Hot-pour crack sealants arrive on the job site as solid blocks that are then melted in a special kettle and applied while still hot. After cooling, the sealant retains its flexibility, allowing it to expand and contract with changing seasons. Throughout its life, hot-pour sealants stay a bit “spongy,” so it is common to see tread marks or even footprints in it once the area is open to traffic. These marks usually disappear with time.
Cold-pour sealants can be water-based or asphalt-based. They typically arrive on the jobsite pre-mixed and can be applied directly from the container. The application method depends on the specific job as well as the contractor’s preference, but options include “puttying” it on, spraying it, pouring it or using a caulking gun. Cold-pour fillers dry to a hard consistency that is lacking in flexibility. During the first freeze following application, it is possible for the “plug” to be forced from the crack, leaving an opening for water to penetrate to the foundation.
Only an experienced parking lot paving contractor can determine the best product to use for filling cracks. The size of the cracks, air temperature and customer’s wishes must all be evaluated. Although the cold-pour method is typically less expensive, its limited life often makes it more costly in the long run.
