Crack sealing can help extend the life of pavement if done properly, but some cracks are just too large to fill with traditional asphalt crack sealant. Cracks larger than 2 inches wide require a more extensive repair process.
1. Asphalt Milling
We begin the repair by removing the top two inches of asphalt centered around the crack.
2. Filling the Cracks
After the area has been milled and cleaned, we fill the crack with traditional rubber asphalt sealant.
3. Installing NW-75 Pavement Underseal Membrane
After filling the cracks, a fabric called NW-75 is placed above the crack. This is the key component that makes our process work best. The fabric forms a membrane that minimizes surface water from penetrating pavement systems and provides a stress relief interlayer which inhibits the growth of reflective cracks.
4. Adding new Hot Mix Asphalt & Compaction
Finally, hot-mix asphalt is added on top of the fabric to fill the void, and compacted to to leave a smooth surface.
