Frequently Asked Questions

How does WS-802 achieve "immediate" traffic opening?

WS-802 uses pressure-sensitive technology. Unlike traditional materials that require solvent evaporation or chemical curing, WS-802 hardens and gains strength through the compaction of passing vehicle tires.

Can I use this material during heavy rain or in standing water?

Yes. WS-802 is designed for all-weather application. Its unique formula allows it to bond effectively even in wet conditions or when the pothole contains water, which is a significant advantage over hot-mix or solvent-based cold patches.

What is the expected lifespan of a repair made with WS-802?

When applied correctly, WS-802 repairs are considered permanent solutions with a durability exceeding 5 years, often outlasting the surrounding pavement.

Is any specialized machinery required for installation?

No specialized machines are required. For small repairs, a simple hand tamper or even the tires of a vehicle can be used for compaction. This makes it ideal for rapid maintenance by a single person.

What is the shelf life and how should it be stored?

WS-802 has an exceptional shelf life of up to 5 years when stored in its original, unopened packaging. It does not harden in the bag, allowing for long-term inventory management.

Is the material environmentally safe?

Absolutely. WS-802 is REACH certified, VOC-free, and produces zero emissions. It is safe for workers to handle and does not leach harmful chemicals into the surrounding soil or water.
