Running tracks are a paved-in-place system. The base, comprised of a single-compound polyurethane binder and machine-installed SBR rubber granules, is what gives a track its “cushion.” After this step is complete, the track is finished with multiple spray applications of 100% solid pigmented polyurethane and EPDM granules, or an environmentally friendly water-based structural spray.
There are several environmental advantages to using a waterborne structural spray instead of a urethane based spray:
- Low to zero VOCs
- Made without isocyanates
- Reduced chemical exposure
- Reduced odors
- Faster dry times – two sprays in one day
- Less prep work and issues with clean up
- When replacing the track, the reduction of harmful chemicals allows for simpler disposal due to reducing hazardous and environmental liabilities

Many tracks are constructed on land adjacent to environmentally sensitive areas. Choosing a waterborne structural spray for these conditions is appropriate to enhance environmental protection and alleviate concerns about potential chemical exposure.
During a recent Gale track project (photos shown to the right), the town chose to use a waterborne structural spray because of the track’s adjacency to wetlands, a perennial stream, and close proximity to residential neighborhoods.
