Product Information

JAS does not merely provide waterproofing materials — we deliver solutions to construction risk.
In an era defined by labor shortages and increasingly extreme climate conditions, JAS supports architects and engineers by introducing science-based standards that shift construction from labor-dependent practices to performance-driven engineering. Through this approach, we help create buildings that are more durable, environmentally responsible, and designed to stand the test of time.

Concrete Waterproofing Process
Integral Waterproofing
Add JAS-UHPWA 101 integral waterproofing admixture directly into the concrete mix.
Crack Filling & Surface Densification
JAS-UHPWA 101 reacts to seal and densify micro-cracks and surface pores.
Nano Hydrophobic Surface Protection
Spray-apply JAS-SUPERWA 201 nano hydrophobic coating to form a transparent protective film on the surface.

The world’s only revolutionary waterproofing material that combines penetration, water resistance, hydrophobicity, and breathability — all in one system — is coming to an exclusive presentation in Taoyuan!
A truly advanced material on par with leading nations, no longer something to admire from overseas.
Independently researched, developed, and manufactured in Taiwan — and available right here, ready for you to use.

This Jun An Shun penetrating waterproofing system strengthens concrete from within, without forming surface films or peeling. It resists dusting, UV degradation, and allows application on damp surfaces. With reinforcement performance lasting up to 30 years, it delivers the lowest life-cycle maintenance cost on the market.
It truly achieves what matters most:
Durability. Sustainability. Efficiency. And exceptional cost savings.
