What is Spray Patching?

Spray patching is a fast, cost-efficient way to make long lasting repairs to damaged pavement. It effectively rejuvenates highways, roads, and parking lots, and reduces further deterioration by cleaning, filling, smoothing and sealing cracks, raveling, potholes, gutter gaps and other bumps and depressions.


  • Low cost maintenance 

  • Protects original investment

  • Prevents moisture from penetrating

  • Can withstand extreme temperatures

  • Less labor intensive allowing crew to be more productive

  • Quick application with the result of longer lasting repairs

What areas can be repaired

  • Potholes

  • Utility cuts

  • Wide cracks

  • Wheel rutting

  • Shoulder breaks

  • Crumbling asphalt

  • Catch basin repairs

  • Depressions / Low spots


Spray injection patching can be “the most economical and longest lasting method of pothole repair.” 

Spray patching is done via a low-pressure system, which delivers the necessary air, aggregate and emulsion for each application. It includes four basic steps. First, all water, dirt and any debris are removed from the pothole. Next, the defected area is sealed with a coat of heated liquid asphalt to help ensure a strong bond between the aggregate mix and existing asphalt. The area is then filled with material, typically consisting of hot asphalt liquid-covered stones, which bonds to the existing pavement.

Within Commercial areas, after compaction with a compactor, the patch is sealed with a coat of liquid asphalt and finally a light layer of fine sand, enabling slow traffic to drive over these patches immediately after repairs are completed. 


The technology has been around for decades and spray patching is a widely accepted form of asphalt repair. 


Spray Patching Can Improve Your ROI


Each year, Mother Nature leaves her stamp on state highways, city and county roads, and even parking lots in the form of potholes. Born from both harsh, cold winter and dry, hot summer weather, potholes show up many times throughout the year and in all regions and climates – no area is immune.

Furthermore, there’s no way to stop them. Regardless of a road’s design and build quality, virtually all asphalt pavement will eventually crack, either from extreme cold, or dry, hot weather. And that crack, combined with heavy traffic, will eventually turn into a full-blown pothole. But those seemingly small holes pack a lot of punch. Potholes potentially cause major damage to vehicles, and since prevention is an impossibility, management becomes key. Cities, counties and states are faced with developing plans to manage pothole repair.


There are numerous methods to repair potholes, from the most basic “fill-and-go” techniques to most complex, where a large area of pavement is removed and replaced. While each offers the same general end-result, the processes, labor requirements, equipment used and final product quality are quite different – and one method has proven itself to be the leader in several areas.


Introduced in the early 1980s, spray injection patching has emerged as the choice method in terms of efficiency, quality and cost-effectiveness. The technique offers several benefits and a considerable potential for return on investment (ROI). Because pothole repair is an ongoing process, and one that has to be dealt with in every city, it only makes sense to consider the method that will offer the greatest productivity, durability and potential for ROI.
