1. Perma-Patch is environmentally friendly with no VOC emissions and little or no waste when poured from a bag. If all material is not used, the bag can be re-closed and used at a later date.
2. Perma-Patch bags can be easily transported in small vehicles, using only one driver/worker, which is extremely helpful during emergency and non-standard work hours.
3. Perma-Patch can be stored in a small warehouse or under tarpaulins, saving space and the cost of a large bulk storage site.
4. Perma-Patch in bags eliminates the possibility of contamination from salt, stone, sand, dirt, etc. that would affect the performance of the product.

1. Perma-Patch is a permanent paving material which is far superior to standard "cold patch" in ease of use and durability. Standard cold patch only holds together temporarily. It rapidly disintegrates much like candy popcorn because of lack of cohesion between its aggregate. Standard cold patch sets up by evaporation of its hydrocarbon solvents. Perma-Patch, on the other hand, is a proprietary formula composed of asphalt, special aggregate and pressure-sensitive plastics. It sets up by compaction rather than by evaporation. It is not temporary, but it is permanent paving. Unlike standard cold patch, Perma-Patch can be feathered to the thickness of its aggregate and adheres so strongly to existing paving that even a shallow dip can be leveled by placing a very thin layer of Perma-Patch on the street surface. Even more significantly, it can be used in standing water with no adverse effects. No tack coat or any other type of adhesive is required to bond Perma-Patch to the existing pavement.

For the repair of potholes and small utility cuts and trenches, Perma-Patch is far more durable than hot mix asphalt for the following reasons:

1. Perma-Patch adheres to the surrounding pavement and acts like a large expansion joint. Because of its self-sealing qualities it will not crack or separate from the existing pavement thereby preventing the infiltration of water. Conversely, a hot asphalt patch will within a short time separate from the surrounding pavement permitting water to flow beneath the patched area. This leads to the rapid deterioration and failure of the patch and surrounding pavement. Potholes will reoccur when repaired with hot mix asphalt.
2. Perma-Patch flexes with movement and vibration, but does not crack like hot mix asphalt; therefore it makes a far superior repair on bridges, around manhole or valve covers and other applications where vibration, movement and heavy pounding are present.
3. Perma-Patch can be used at any temperature, any season. Hot mix asphalt is not even manufactured during cold weather because it crystallizes when used under 35 degrees F. Perma-Patch unlike hot mix asphalt can be used in wet rainy weather with no adverse effects and yet remain permanent.
4. Tack coat is required in the application of hot asphalt but there is no need to use tack coat with Perma-Patch as it is self-adhesive. Perma-Patch creates a very strong bond and adheres to stone, wood, steel, asphalt, and concrete. However, it does not adhere to rubber tires.
5. A dump truck, a large crew of workers and heavy compaction equipment is required for the placement of hot mix asphalt, whereas minimal or no equipment, is required for placing and compacting Perma-Patch. Perma-Patch can be poured directly from the bag into the pothole or utility cut and compacted by the weight of traffic. For better appearing repairs, or for repairs of lightly traveled areas, vibratory plate compactors or hand tampers may be used.
6. Hot mix asphalt requires a trip to the asphalt plant and a long wait to be loaded. In addition, any hot asphalt that is not promptly used must be discarded. There is no delay or expensive dump fees when using Perma-Patch.

Perma-Patch has been used for over twenty years by contractors and maintenance personnel to make high quality, permanent repairs while minimizing traffic interruptions. Perma-Patch eliminates constant repeat repairs necessary when using standard cold patch and even hot asphalt on the same damaged areas. Sewer, water, and gas utility contractors, fiber optic cable installers, location and test pit investigators using conventional or vacuum method technology have successfully used Perma-Patch to permanently repair their utility cuts. Perma-Patch has shown its reliability and durability on thousands of highways and bridges throughout the United States and in many foreign countries over many years.

Wherever repairs to utility cuts, potholes, or roads are made using hot mix asphalt, within three months after a standard repair, there will be a gradual increase in the separation of the old paving from the new paving. This separation is due to the difference in the thermal expansion rate between the new and the old pavement. This separation allows water to penetrate under the paved area which leads not only to gradual disintegration of the repaired area, but extends to the existing street base. This problem is compounded by freezing and/or by wet conditions. The practical solution to this problem is to substitute Perma-Patch for hot mix asphalt. Perma-Patch eliminates this separation, because underlying the hard surface layer of Perma-Patch is a pliable layer of Perma-Patch acting as a large expansion joint constantly sealing the interface between the surrounding paving and the new Perma-Patch repair material.

Immediately after the repair is made, Perma-Patch is ready for traffic. Since Perma-Patch contains pressure-sensitive plastics, the greater the amount of traffic, the faster Perma-Patch sets up

There is no need to resurface the areas which have been repaired with Perma-Patch as Perma-Patch becomes as durable and long lasting as the surrounding paved areas. However, if desired, the Perma-Patch repair may be resurfaced like any other pavement.
