Armtix, made from bulletproof-grade material
—the top choice for rooftop waterproofing projects on village houses
Armtix specializes in rooftop waterproofing for village houses. Using highly elastic waterproofing materials developed based on bulletproof-grade technology, we provide a one-time, permanent solution to leaks in complex environments such as village house rooftops exposed to direct sunlight and those with solar panel installations or glass-enclosed extensions. Our dedicated team will respond to inquiries as soon as possible and can conduct a preliminary assessment of the cause and general direction of the water seepage via WhatsApp.
A Leaky Rooftop in a Village House Can Turn Into a Nightmare
Water stains, peeling paint, and mold on the ceiling
At first, it was just a faint yellow water stain, but with each rainfall, the stain spread like a map. The paint began to bulge and bubble, and eventually flaked off in pieces.
Concrete spalling and exposed rebar compromise structural safety
Moisture penetrates deep into the concrete and comes into contact with the rebar, causing it to rust and expand, which generates enormous internal pressure and results in what is commonly known as “concrete spalling.”
Moisture in electrical wires and light fixtures can cause short circuits.
Water that accumulates on the rooftop often flows down through the concealed electrical conduits in the concrete, causing water to drip from the living room chandelier, ceiling light fixtures, and even wall-mounted switches.
Differences Between Village Houses and Regular Apartment Buildings
When a village house rooftop leaks, the owners of the top-floor units are usually the first to be affected.The concrete roof slab serves as the ceiling of the top-floor unit. Once the waterproofing layer ages and cracks, rainwater seeps in, and the owner’s ceiling is the first to be affected. Unlike typical high-rises, which have management companies that perform regular maintenance on exterior walls and rooftops, when water seepage in village houses spreads downward through cracks in the exterior walls or hidden pipes, owners often have to discover and address the issue on their own. Therefore, addressing the problem early on is far more cost-effective than repairing it after the fact.
Why Are the Rooftops of Village Houses Particularly Prone to Leaks?
- Unshielded Exposure to the Sun + Large Temperature Fluctuations: Most village houses in the New Territories are open on all four sides, resulting in extreme day-to-night temperature fluctuations on the rooftops, which cause traditional waterproofing layers to crack due to thermal expansion and contraction.
- Solar Panel/Glass Room Addition: When installing the base, the floor slab is penetrated; if not properly sealed, rainwater can seep in along the brackets and screw holes.
- Junction between the drain outlet and the parapet: A common gap found on the rooftops of village houses, where water accumulates over time and seeps into the structural layer.
- Aging and deterioration of old materials: The standard rooftop waterproofing compound used many years ago has lost its UV resistance and is no longer thick enough.
Armtix Village House Rooftop Waterproofing Project: A One-Time Solution to Put an End to Your Problems
Made from bulletproof-grade materials
Designed specifically for the rooftops of village houses, it seamlessly covers complex details such as solar panel bases, air conditioner mounts, and the edges of glass structures, preventing the hidden gaps that traditional materials leave in irregular areas.
Forms a film in as little as 20 seconds
Given Hong Kong’s unpredictable weather, rapid curing reduces the risk of rain disrupting construction and makes it easier to manage the construction schedule.
10x UV Protection for Use in Intense Sunlight
Unlike traditional materials, it withstands prolonged exposure to sunlight, reducing the likelihood of chalking and cracking, making it more suitable for environments such as the rooftops of village houses that are constantly exposed to direct sunlight without any shade.
Low-Disturbance Construction Plan
This can be done without completely gutting the space, thereby reducing noise, dust, and disruption to residents, making it a more resident-friendly option for village houses that are still occupied.
Armtix Village House Rooftop Waterproofing Process
Free Village House Inspections
A specialist will visit the site to inspect the rooftop, the third-floor ceiling, the parapet, and the drain outlets, using specialized equipment to determine the extent of water leakage if necessary.
Roof Deck Cleaning
Use a high-pressure water jet to remove moss and dirt, repair visible cracks and loose materials, and lay the groundwork for subsequent construction work.
Reinforcement at Key Locations
Localized reinforcement of solar panel bases, glass greenhouse footings, the bases of drainpipes, and the bottoms of parapets
Spray-Applied Waterproofing Coating
Sprays evenly and forms a film in as little as 20 seconds, creating a continuous, seamless waterproof layer
Acceptance Testing and Maintenance
The project will not be considered complete until standard water testing has been conducted to ensure there are no further leaks, and a 10-year warranty will be provided.
Schedule a Waterproofing Inspection for Your Village House Rooftop Today
Don’t wait until the next heavy rain to start regretting it—the longer you put off fixing a leaky rooftop in your village house, the more expensive it will become. Arranging an inspection early on can effectively prevent more serious structural issues, such as concrete spalling and exposed rebar.
