Hong Kong Rooftop Waterproofing Projects
Utilizes Military-Grade Waterproofing Technology
Armtix specializes in rooftop waterproofing in Hong Kong. By combining proprietary, patented waterproofing materials with a film-forming technology that sets in as fast as 20 seconds, we provide long-lasting protection for building rooftops. The material forms a seamless film upon application and features 10 times the UV resistance, reducing moisture penetration into the structure at the source and providing long-term protection against storms, heavy rain, and humid environments.We offer a one-stop service ranging from on-site inspections and rooftop leak-proofing project planning to construction and maintenance. We provide transparent quotes for rooftop waterproofing based on actual conditions, allowing you to choose the solution that best suits your needs.
Prevents water seepage at the source and provides long-lasting protection against intense sunlight, heavy rain, and humidity
Roofs in Hong Kong are constantly exposed to intense sunlight, standing water, and temperature fluctuations. Once the existing waterproofing layer ages or blisters, even repeated surface repairs with sealant typically only provide temporary protection. Water stains and peeling may still appear on interior ceilings and walls. Armtix addresses this issue with a comprehensive roof waterproofing system, planning the waterproofing structure from the base layer upward to reduce the risk of similar problems and repeated repairs in the future.

Armtix Solves Recurring Roof Leak Problems in One Go
Persistent roof leaks are often caused by the original waterproofing layer reaching the end of its service life, hollows or cracks in the brickwork or mortar layer, chronic water accumulation due to poor drainage design, and unaddressed hairline cracks caused by temperature fluctuations. Simply applying a waterproofing sealant to the surface usually only provides temporary relief and fails to effectively seal the leak path.Before planning a rooftop waterproofing project, Armtix conducts a detailed survey to assess the condition of the rooftop surface and substrate, then determines whether partial or complete removal is necessary. Subsequently, a seamless, sprayed membrane is applied to create a monolithic waterproofing layer, accompanied by a standardized water-test acceptance procedure. This ensures that structural issues with the waterproofing layer are resolved in a single project, thereby reducing the need for repeated repairs in the future.

Roofs of Residential Buildings
Residential rooftops are often exposed to prolonged sunlight and standing water. If the waterproofing layer deteriorates, it can easily lead to ceiling peeling and damp walls in the top-floor units. Armtix is ideal for restoring waterproofing on residential rooftops, helping to reduce the risk of indoor water seepage.
Roof of a Village House
For rooftops with cracked tiles, hollow spots in the mortar, and poor drainage, this approach extends the overall service life. By completely renovating the rooftop surface and waterproofing layers, the structure can more effectively withstand heavy rainfall and prolonged standing water.
Load Platform and Equipment Level
Ideal for locations such as water towers and equipment rooms, it balances load-bearing capacity with waterproofing performance while minimizing cracking caused by vibrations. The flexible waterproofing layer helps distribute stress caused by loads and minor movements.
Roof of the Commerce and Industry Building
Ideal for large-area commercial and industrial rooftops with extensive equipment and piping, helping to minimize seams and areas prone to water leakage. The seamless spray-applied coating method facilitates the treatment of various wall penetrations and areas with elevation differences, enhancing stability.
School/Organization
Suitable for rooftops adjacent to classrooms and public spaces, facilitating the maintenance of daily operations. Disruption to teachers, students, and other users during construction is minimal, while safety and environmental requirements are also met.
Armtix Core Technology: Comprehensive Protection for Hong Kong Rooftops
10x UV protection, long-lasting weather-resistant protection
Compared to traditional rooftop waterproofing coatings, Armtix is more resilient to prolonged sun exposure and temperature fluctuations, making it particularly suitable for rooftops of village houses and top-floor units.
- 10x Sun Protection & UV Protection
- Highly effective heat resistance and weather resistance; suitable for all types of exterior wall environments; extends the service life of the waterproofing system
- Operating Temperature: -20°C to 40°C; suitable for Hong Kong's hot and humid climate
Fast-curing gel in as little as 20 seconds—faster and more reliable application
For rooftop waterproofing projects, a shorter site closure period means residents can resume normal use more quickly and reduces the likelihood of work being forced to halt due to unexpected weather.
- Faster construction
- Reduce Project Delays
- Reduce wait times
- Better suited for rainy and humid environments
Safe and Environmentally Friendly Materials for Rooftop Waterproofing
Many homeowners are concerned about whether rooftop waterproofing projects will produce strong odors or affect indoor air quality—a concern that is particularly acute for households with children or elderly residents. Armtix materials are designed to balance waterproofing performance with health and well-being, and their features make them especially suitable for spaces intended for long-term use, such as residential homes and schools.
100% solids content
High-solids, solvent-free formula—more environmentally friendly and more stable.
Odorless Installation
There are no irritating odors during the construction process, making it more comfortable and reassuring.
Non-flammable
It has flame-retardant properties, which help enhance overall safety.
Suitable for homes and schools
Suitable for residential, school, commercial, and various other settings.
Armtix Roof Waterproofing Technical Specifications
Armtix rooftop waterproofing technology is specifically designed for concrete rooftops commonly found in Hong Kong. Whether on residential rooftops or the rooftops of commercial and industrial buildings, it maintains consistent waterproofing performance despite temperature fluctuations and daily operational loads.
High-Strength Elastic Waterproof Coating
Features a polybenzoxazine elastic waterproof coating with high strength and high puncture resistance, specifically designed for the actual conditions of rooftops in Hong Kong.
Tensile strength up to approximately 21 MPa
Tear strength of 65–78 kN/m
Integrated Seamless Waterproofing Layer
Creates a seamless, integrated waterproofing layer, reducing cold joints and traditional membrane overlaps.
This helps minimize the risk of water leakage in hard-to-reach areas and can adapt to varying elevation changes and detailed areas on the roof.
High Elongation
The material has an elongation at break of approximately 380%–520%, allowing it to accommodate structural expansion and contraction caused by temperature fluctuations.
This helps maintain the overall integrity of the waterproofing layer and reduces the risk of water infiltration caused by cracking.
How Are Roof Waterproofing Quotes Calculated?
There is no fixed price range for rooftop waterproofing quotes that applies to all situations; prices typically vary based on the following key factors:
- Roof Terrace Area and Shape (whether there are many corners or significant elevation changes)
- Current condition of the roof deck and waterproofing layer (whether partial or complete removal is required)
- Building Height and Access Difficulty (whether scaffolding or additional safety measures are required)
- Grade of Waterproof Material Selected and Expected Service Life
Therefore, without a firsthand understanding of the on-site conditions, any single price-per-square-foot reference can only serve as a rough guide. Armtix will first assess the situation preliminarily through photographs, then arrange a free on-site inspection. Based on the actual conditions, we will provide a rooftop waterproofing quote that clearly lists the work processes and materials used, along with the scope of work and warranty period, allowing homeowners to confidently compare different options.
