Armtix Wanji | Professional Waterproofing Contractor in Hong Kong
Based on bulletproof-grade material technology, our services cover a wide range of waterproofing needs, including rooftops, exterior walls, village houses, and single-family homes. The coating forms a protective film in as little as 20 seconds and offers 10 times the UV resistance, blocking water penetration at the source and providing long-lasting protection against intense sunlight, heavy rain, and humidity.
How to Choose a Waterproofing Company in Hong Kong?
Armtix uses bulletproof-grade technology to permanently eliminate water seepage.
Armtix is a waterproofing system developed by a professional Hong Kong-based waterproofing company. It prevents water seepage at the source through seamless spray-applied coating, rapid curing in as little as 20 seconds, and 10 times the UV resistance. We undertake waterproofing projects of all sizes and have completed waterproofing improvements for hundreds of housing estates, village houses, and single-family homes throughout Hong Kong.
Armtix Professional Waterproofing Solves Problems at the Source
Recurring water seepage is often caused by improper preparation of the substrate, cracks resulting from thermal expansion and contraction of materials, or long-term exposure to sunlight leading to deterioration. Armtix addresses these root causes one by one through the following five approaches:
Forms a film in as little as 20 seconds
- Traditional lead time: 4–6 hours
- Forms a gel film in as little as 20 seconds

Every strength stands the test of time
The tensile and tear strength of this material, developed using bulletproof-grade technology, generally exceeds that of standard waterproof coatings on the market. Even as Hong Kong’s building structures undergo years of thermal expansion and contraction, the material remains capable of withstanding tension without cracking easily.The “single-coat application” method eliminates the waiting time associated with traditional multi-layer plastering, allowing projects to be completed faster and at a lower cost. During the ten-year warranty period, any abnormalities are addressed immediately upon discovery, preventing minor issues from escalating into major repairs and ensuring the long-term preservation of the property’s value.
