Frequently Asked Questions
How does the "Pressure-Sensitive" technology work?
Unlike traditional mixes that rely on solvent evaporation or water activation, WS-802 hardens and gains strength through the physical pressure of vehicle compaction. The more traffic passes over it, the more stable it becomes.
Can I really use this in the middle of a rainstorm?
Yes. WS-802 is designed for all-weather application. It displaces water effectively and maintains a strong bond with the existing pavement even in wet or rainy conditions.
Do I need heavy machinery for installation?
No. For small repairs, a single person can apply the material using basic hand tools. For larger potholes, standard traffic compaction is often sufficient to set the material.
What is the shelf life of the material?
WS-802 has an industry-leading shelf life of over 5 years when stored in its original bagged packaging, making it ideal for emergency stockpiling.
Is this solution permanent or temporary?
WS-802 provides a high-performance, permanent repair solution with a certified durability of over 5 years, outlasting traditional cold patch materials significantly.
Is the material environmentally safe?
Absolutely. It is VOC-free, produces zero emissions during application, and any leftover material is 100% recyclable, making it the greenest choice for road maintenance.
