Application
1.Make sure the roof deck is smooth,clean and dry(Moisture<9%),then apply the surface of roof deck with a kind bitumen paint till dry.
2. There are two methods in application:
One way is by heating and melting method---Heat the membrane and roof deck surface by heating and melting method to be nearly melted(not flowing),then install the membrane fully bonded to the roof deck with overlaps of 5-250px.
The other way is by cold adhesive method---Pour the cold adhesive on the roof deck then roll the membrane to install it to be fully sticked to roof deck.
By heating and melting method and by cold adhesive can be used in alternation as requested.
3.After application,, a full serious inspection is required,that’s to make sure no air bubble,,no fold,,no falling away etc. and guarantee the waterproof life.
Requirements for construction
1.The base should be dry and clean. Do not work in the rainy or snowy day.
2.Do not work under heavy wind(above 5 grade)
3.Unsuitable for construction below 5°C
4.If it is rain or snow in the process of construction, protective measure to the laid membrane is must.
5.All the workers should put on special uniforms to keep safe when installing. There should be equipments for fire controls.

FAQ
Q: What's the delivery time ?
A: 3-5 days for 1-600 rolls, 10-15 days for container.
Q: What's the payment terms ?
A: TT/LC
Q: How do you make replacement with quality problems ?
A: New replacement will be packed into your next order or send to you directly after receive video or photo about quality problems.
- Q: Are waterproofing membranes resistant to ammonia?
- Yes, waterproofing membranes are generally resistant to ammonia.
- Q: Are waterproofing membranes resistant to algae growth?
- Yes, waterproofing membranes are generally resistant to algae growth. Waterproofing membranes are designed to be highly durable and resistant to various environmental factors, including the growth of algae. They are typically made of materials such as PVC, TPO, or EPDM that are inherently resistant to algae and other microbial growth. Additionally, waterproofing membranes are often treated with anti-algae and anti-fungal agents during their manufacturing process to further enhance their resistance to algae growth. However, it is important to note that while waterproofing membranes are resistant to algae growth, they may still require regular cleaning and maintenance to ensure their long-term performance and prevent any potential build-up of dirt or debris that could potentially provide a favorable environment for algae to grow.
- Q: How does a waterproofing membrane handle movement of a building due to settling or seismic activity?
- A waterproofing membrane is designed to handle movement of a building caused by settling or seismic activity by providing flexibility and elasticity. It can accommodate small shifts and vibrations without cracking or breaking, ensuring that the waterproof barrier remains intact. The membrane's ability to stretch and contract helps it to adapt to the movement of the structure, preventing water intrusion and maintaining its effectiveness in safeguarding the building against moisture damage.
- Q: Are waterproofing membranes resistant to oil and grease?
- Waterproofing membranes are commonly resistant to oil and grease. They are specifically designed to prevent water infiltration and can also withstand exposure to chemicals like oil and grease. This resistance is achieved by using specialized materials and coatings that can repel or prevent absorption of oil and grease. However, it is crucial to mention that the level of resistance may differ based on the type and brand of the waterproofing membrane. Thus, it is recommended to refer to the manufacturer's specifications or seek professional advice to ensure the chosen membrane is suitable for the specific application and level of oil and grease exposure.
- Q: Can a waterproofing membrane be used on underground structures?
- Underground structures can benefit from the use of a waterproofing membrane. It is a common practice to apply these membranes to basements, tunnels, and underground parking garages in order to prevent water infiltration and protect against water damage. Typically made of materials like bitumen, EPDM, or PVC, these membranes are applied to the exterior walls or floors of the structure. Acting as a barrier, they prevent water from seeping in and causing problems like dampness, mold, or structural damage. Moreover, waterproofing membranes can also minimize the risk of leaks, extend the lifespan of the structure, and enhance its durability. Therefore, it is highly recommended to use a waterproofing membrane on underground structures to ensure their long-term integrity and functionality.
- Q: Can waterproofing membranes be used on metal roofs?
- Yes, waterproofing membranes can be used on metal roofs. Waterproofing membranes are a popular choice for protecting and sealing roofs, including metal roofs. These membranes are designed to provide a barrier against water penetration, protecting the roof structure and preventing leaks. They can be applied directly to the metal roof surface, creating a watertight seal that is resistant to moisture, UV rays, and other environmental factors. Waterproofing membranes can effectively extend the lifespan of metal roofs by preventing rust and corrosion, while also improving energy efficiency by reducing heat transfer. Therefore, using waterproofing membranes on metal roofs is a viable and effective solution for ensuring durability and longevity.
- Q: Can a waterproofing membrane be used on tile surfaces?
- Yes, a waterproofing membrane can be used on tile surfaces. It helps to provide an additional layer of protection against water damage and helps to prevent water penetration through the tile surface and grout lines.
- Q: How does a waterproofing membrane handle joint or crack movements?
- A waterproofing membrane is designed to handle joint or crack movements by being flexible and elastic. It is constructed using materials that can stretch and move with the underlying structure, allowing for expansion and contraction without compromising the watertight seal. This flexibility ensures that the membrane can accommodate any movements in the joints or cracks, preventing water from seeping through and causing damage. Additionally, some waterproofing membranes have added features such as reinforcement or bridging capabilities, which further enhance their ability to handle joint or crack movements. Overall, a waterproofing membrane is specifically engineered to effectively seal and protect against water intrusion while accommodating any movements in the joints or cracks of a structure.
- Q: Are waterproofing membranes flexible?
- Waterproofing membranes, generally, exhibit flexibility. Their purpose is to be adaptable, enabling them to mold and adjust to the contours and shifts of the surfaces they are applied on. This adaptability effectively seals off any openings, fissures, or connections, effectively barring water infiltration into the foundation. Additionally, the elasticity of waterproofing membranes empowers them to endure the expansion and contraction caused by temperature fluctuations or structural shifts. In conclusion, the flexibility of waterproofing membranes is an essential attribute that guarantees their resilience and efficacy in safeguarding structures against water-related harm.
- Q: Is a waterproofing membrane resistant to mold and mildew growth?
- Indeed, the resistance of a waterproofing membrane to the growth of mold and mildew stems from its specific design, which aims to establish a barrier against moisture infiltration. This impedes water seepage and the subsequent development of mold and mildew. Through the effective sealing of the area, these membranes eradicate the favorable conditions for the proliferation of mold and mildew, such as dampness and moisture. However, it is important to acknowledge that although the membrane itself exhibits resistance to mold and mildew growth, it does not guarantee absolute protection against these issues. Proper installation, regular maintenance, and ensuring adequate ventilation play pivotal roles in preventing the long-term growth of mold and mildew.
