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: Can a waterproofing membrane be used on EPDM roofs?
- Yes, a waterproofing membrane can be used on EPDM roofs. EPDM (ethylene propylene diene terpolymer) is a highly durable and flexible synthetic rubber roofing material commonly used for low-slope and flat roofs. While EPDM roofs are already waterproof, applying an additional waterproofing membrane can provide an extra layer of protection and enhance the roof's longevity. The waterproofing membrane can act as a barrier against water infiltration, preventing leaks and moisture damage. However, it is important to ensure that the waterproofing membrane is compatible with EPDM and follows the manufacturer's guidelines for installation to maintain the roof's integrity.
- Q: Can a waterproofing membrane be used for a shopping mall?
- Yes, a waterproofing membrane can be used for a shopping mall. A shopping mall typically has multiple levels and a large surface area, which makes it susceptible to water infiltration from rain, plumbing leaks, or other sources. Installing a waterproofing membrane can provide an effective solution to protect the structure and its contents from water damage. The membrane is typically applied to the exterior walls, roofs, and foundation of the shopping mall to create a barrier against moisture penetration. It acts as a protective layer that prevents water from seeping into the building, reducing the risk of structural damage, mold growth, and other related issues. Additionally, a properly installed waterproofing membrane can also help to improve energy efficiency by reducing heat loss and preventing water-related deterioration of insulation materials. Therefore, using a waterproofing membrane is a wise choice for ensuring the long-term durability and functionality of a shopping mall.
- Q: Can a waterproofing membrane be used in conjunction with paint or coatings?
- Yes, a waterproofing membrane can be used in conjunction with paint or coatings. The membrane provides a barrier against water intrusion, while the paint or coatings provide additional protection and aesthetic appeal.
- Q: Can a waterproofing membrane be used on metal block surfaces?
- Metal block surfaces can indeed benefit from the use of a waterproofing membrane. These membranes are specifically designed to form a barrier against water and moisture, and they are versatile enough to be applied to various types of surfaces, including metal. By adhering to the metal surface, the membrane creates a protective layer that not only prevents water infiltration but also safeguards the metal against rust and corrosion. However, it is crucial to guarantee that the metal surface is thoroughly cleaned, dried, and appropriately prepared before the application of the waterproofing membrane. This preparation ensures optimal adhesion and effectiveness. For specific instructions on using a waterproofing membrane on metal block surfaces, it is highly recommended to consult a professional or refer to the manufacturer's guidelines.
- Q: What is the material on the insulation layer on the waterproofing membrane?
- The isolation layer of the roof waterproof layer is generally set between the waterproof layer and the above rigid protective layer, and he has two roles. 1, the surface of the rigid layer (usually 40mm thick fine stone concrete) will have thermal expansion and contraction deformation, if the waterproof layer and the rigid layer is very good, rigid layer deformation will affect the deformation of the waterproof layer, so there may be waterproof Layer to produce a direct cracking or long-term fatigue damage, so the two tectonic layers should be set with a sliding function of the isolation layer;
- Q: Can a waterproofing membrane be used on precast stone block surfaces?
- Yes, a waterproofing membrane can be used on precast stone block surfaces. A waterproofing membrane is designed to provide a protective barrier against water infiltration, and it can be applied to various surfaces, including precast stone blocks, to prevent water damage and ensure the longevity of the structure.
- Q: Can a waterproofing membrane be used on precast concrete block surfaces?
- Yes, a waterproofing membrane can be used on precast concrete block surfaces. It helps to prevent water penetration and protects the structure from potential damage caused by moisture.
- Q: Can a waterproofing membrane be used in conjunction with expansion joint systems?
- Yes, a waterproofing membrane can be used in conjunction with expansion joint systems. Waterproofing membranes are commonly used to prevent water infiltration and protect structures from moisture damage. Expansion joint systems, on the other hand, are installed to allow for movement and accommodate thermal expansion and contraction in structures. By combining the use of a waterproofing membrane and expansion joint systems, it is possible to provide both waterproofing and movement accommodation in a structure. This ensures that the structure remains protected from water damage while allowing for necessary movement. It is important to properly design and install both the waterproofing membrane and the expansion joint system to ensure their compatibility and effectiveness.
- Q: Can a waterproofing membrane be used on stone block surfaces?
- Yes, a waterproofing membrane can be used on stone block surfaces. A waterproofing membrane is designed to provide a protective barrier against water and moisture, and it can be applied to various surfaces, including stone blocks. This membrane acts as a barrier, preventing water from penetrating into the stone and causing damage such as cracking, spalling, or efflorescence. It helps to protect the stone blocks from water-related issues, including freeze-thaw damage and the growth of mold and mildew. Additionally, a waterproofing membrane can also enhance the overall durability and longevity of the stone blocks by protecting them from water damage. Therefore, using a waterproofing membrane on stone block surfaces is a recommended solution to ensure their long-term integrity and appearance.
- Q: Does a waterproofing membrane require any special precautions during installation?
- Yes, a waterproofing membrane does require special precautions during installation. It is important to ensure that the surface to be waterproofed is clean, dry, and free from any contaminants or loose materials. The membrane should be installed in accordance with the manufacturer's instructions, paying attention to proper overlap and seam sealing. It is also crucial to inspect the membrane for any damage or defects prior to installation. Additionally, proper safety measures should be taken, such as wearing protective clothing and using appropriate tools and equipment.
