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.

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: Does a waterproofing membrane provide any insulating properties?
- A waterproofing membrane does not offer any insulation. Its main purpose is to stop water or moisture from entering a building or roof. It acts as a protective barrier, preventing damage to the underlying materials. Insulation, on the other hand, is specifically designed to minimize the transfer of heat, sound, or electricity. While both waterproofing and insulation are crucial for maintaining a structure's integrity and functionality, they serve distinct purposes and should not be mistaken for each other.
- Q: How does a waterproofing membrane handle water migration through the substrate?
- A waterproofing membrane handles water migration through the substrate by forming a barrier that prevents the water from penetrating and reaching the underlying surface. The membrane acts as a protective layer, effectively sealing off the substrate and preventing any water from seeping through.
- Q: Can a waterproofing membrane be used on retaining walls?
- Yes, a waterproofing membrane can be used on retaining walls. Retaining walls are often exposed to moisture and hydrostatic pressure, which can lead to water infiltration and deterioration of the structure. Applying a waterproofing membrane on the retaining wall can help prevent water penetration, protect the wall from moisture-related damage, and prolong its lifespan. The membrane acts as a barrier, preventing water from seeping into the wall and causing potential issues such as efflorescence, cracks, or erosion. It is important to choose a waterproofing membrane that is specifically designed for below-grade applications and is capable of withstanding the pressure exerted by the retained soil. Additionally, proper installation techniques and appropriate drainage systems should be considered to ensure the effectiveness of the waterproofing membrane on retaining walls.
- Q: Are waterproofing membranes resistant to wind-driven rain?
- Waterproofing membranes, in general, exhibit resistance to rain propelled by wind. Their purpose is to establish a safeguard against the intrusion of moisture, specifically rainwater. These membranes are commonly constructed from rubber, asphalt, or synthetic polymers, all of which possess a formidable ability to repel water. Moreover, numerous waterproofing membranes are fortified with additives or multiple layers to augment their robustness and longevity, enabling them to endure the forceful impact of wind-driven rain. Nevertheless, it is crucial to acknowledge that the efficacy of waterproofing membranes may be contingent upon the meticulousness of the installation techniques employed and the quality of the materials utilized.
- Q: Can a waterproofing membrane be used on tunnels with architectural features?
- Indeed, tunnels with architectural features can benefit from the application of a waterproofing membrane. Such membranes possess versatility, enabling their usage on different structures, including tunnels with architectural elements. Their primary purpose is to establish a protective barrier against water infiltration, consequently safeguarding the structure against moisture-related harm. Regardless of the tunnel's unique architectural components, such as curves, arches, or decorative embellishments, a tailored waterproofing membrane can be tailored and implemented to ensure optimal water resistance. Therefore, it is imperative to seek guidance from a proficient waterproofing specialist experienced in working with tunnels and architectural features. They will assist in determining the most suitable membrane system for the specific project prerequisites.
- Q: Can a waterproofing membrane be used on precast steel surfaces?
- Indeed, precast steel surfaces can benefit from the utilization of a waterproofing membrane. These membranes are specifically engineered to serve as a safeguard against water infiltration, making them suitable for various surfaces, including precast steel. By acting as a waterproof shield, the membrane effectively blocks water from penetrating the surface and causing any potential harm. It is imperative to ensure that the surface is adequately primed and sanitized prior to applying the membrane to ensure optimal adhesion and efficacy. Furthermore, seeking advice from a qualified waterproofing contractor is highly recommended in order to identify the most suitable membrane type and application technique for the specific precast steel surface.
- Q: Can waterproofing membranes be used on concrete planters?
- Yes, waterproofing membranes can be used on concrete planters to prevent water leakage and protect the concrete from moisture damage.
- Q: Can a waterproofing membrane be used on plaster surfaces?
- Plaster surfaces can benefit from the use of a waterproofing membrane. Due to its porous nature, plaster readily absorbs water, which can lead to damage caused by moisture. By applying a waterproofing membrane to plaster surfaces, a barrier is created to prevent water infiltration. This protective measure safeguards against problems like mold, mildew, and deterioration caused by moisture. Before applying the membrane, it is crucial to ensure the plaster surface is clean, dry, and devoid of loose or flaking material. It is also important to follow proper surface preparation and application techniques to guarantee the effectiveness and durability of the waterproofing system.
- Q: Can a waterproofing membrane be used for residential swimming pools?
- Yes, a waterproofing membrane can be used for residential swimming pools. Waterproofing membranes are commonly used in construction to prevent water penetration and can be applied to various surfaces such as concrete, tile, and metal. They create a barrier that prevents water from seeping into the pool structure, which helps to maintain the integrity of the pool and prevent leaks. Additionally, waterproofing membranes can also protect against other forms of damage such as corrosion and deterioration caused by chemicals or harsh weather conditions. It is important to select a high-quality waterproofing membrane that is specifically designed for swimming pool applications to ensure long-lasting protection and durability.
- Q: Can a waterproofing membrane be installed on bathroom or shower walls?
- Yes, a waterproofing membrane can be installed on bathroom or shower walls. In fact, it is highly recommended to have a waterproofing membrane in place to prevent water damage and leakage. The membrane acts as a barrier, preventing water from seeping through the walls and causing potential mold, mildew, or structural damage. It is typically applied before tiling, ensuring that the entire surface is protected. This is especially important in areas prone to high moisture levels, such as bathrooms and showers. By installing a waterproofing membrane, you can ensure the longevity and durability of your walls, as well as maintain a safe and healthy environment in your bathroom or shower.
