Product Description

Product Introduction

 

Bitumen, the revered champion of the construction world, known as asphalt, boasts a dense, black, and highly viscous nature derived from petroleum. This extraordinary waterproofing agent is celebrated for its unparalleled performance, making it an indispensable asset across the construction sector. Bituminous membranes stand as the quintessential choice for comprehensive waterproofing solutions, safeguarding roofs, basements, and underground structures, and extending their protective embrace to bridges and a multitude of constructions. There are primarily two distinguished application techniques for these exceptional bitumen membranes.
The first is the renowned Torch-on method, delivering exceptional durability, while the second is the intuitive Self-adhesive approach, offering unmatched ease of use.
Torch-on bituminous membranes are your go-to solution for any weather scenario, seamlessly blending versatility and simplicity. When CHENHUA membranes are expertly applied, they metamorphose into a seamless, watertight barrier, intimately fused to the surface for ultimate protection.

Torch Down Bitumen Waterproof Membranes are the preferred choice for impeccable waterproofing and seepage-proofing across a wide array of building grades. Whether for exposed or concealed areas, these membranes excel in securing flat roofs, sloped roofs, underground spaces, tunnels, bridges, parking lots, reservoirs, and an extensive array of applications.

Application Method:
1. Substrate:
Ensure that the substrate is impeccably clean, dry, and free from contaminants, ready for an immaculate application.
All dust, along with any loose and friable materials, must be meticulously removed to ensure a flawless surface.
Blowholes and voids should be fully exposed and expertly repaired to guarantee optimal application quality.
2. Primer:
Before placing the membrane, apply primer with precision. Clean the substrate using a reliable dust catcher or blower, then coat it with a premium treatment primer to amplify waterproofing, ensuring effective dust consolidation and superior adhesion.
3. Membrane Placement:
*Unroll the torch-on membrane with precision, aligning it accurately before commencing the torching or bonding process.
*Lay each membrane in parallel, ensuring they are staggered by at least 1 meter to avoid coinciding joints, promoting optimal stability.
*Alternating the end-to-end overlaps is crucial, avoiding alignment along a single line for enhanced structural integrity.
*Always initiate at the lowest slope height, prioritizing critical areas such as drains, downpipes, or other pivotal details.
*During the torching process, simultaneously heat both the membrane and substrate, focusing on the roll and overlapping areas for a secure, lasting bond.
*Precisely weld overlaps to ensure a pristine trickle of melted mixture, about 1 cm wide, along the overlap line for a flawless finish.
4.Employ a roller to firmly compress the membrane surface, ensuring impeccable adhesion that stands the test of time.


Attention:
1. The substrate must be dry and clean. Work should be avoided on rainy or snowy days to achieve optimal results.
2. Avoid working in winds stronger than grade 5 to ensure both safety and quality are maintained.
3. Construction should not proceed if the temperature is below 5°C to ensure the reliability of the installation.
4. In the event of rain or snow during construction, implementing protective measures for the laid membrane is crucial to uphold quality.
5. All personnel must wear designated safety uniforms, and it is mandatory to have fire control equipment readily available during installation.


Packing and Shipping:
1. Store membranes in a dry, well-ventilated environment to preserve their pristine quality.
2. Different types of membranes should be stored separately to prevent any mixing and ensure product integrity.
3. Under optimal conditions, the storage duration is reliably one year from the production date, ensuring sustained quality.
4. During transportation, it is crucial that membrane rolls are stored in a vertical position and shielded meticulously from exposure to sunlight and rain to ensure optimal preservation and longevity of the product.

1) What is the preferred size for the Torch-on bitumen membrane that customers are seeking?
-The size of 3mm x 1m x 10m, topped with either PE or sand granular finish, is the most popular choice, providing unparalleled versatility and superior performance for various applications.
-Dimensions: With a robust thickness of 4mm, a width of 1m, and a length of 10m, this option is available with a sophisticated finish of either PE film or sand granular top.

2) What is the fundamental difference between SBS and APP modifiers?
-SBS and APP are state-of-the-art modifiers that considerably enhance the performance of membranes. SBS modifiers are unparalleled in boosting the cold resistance of waterproof membranes, making them ideal for colder climates. In contrast, APP modifiers excel in augmenting heat resistance, perfect for high-temperature environments. Despite their similar appearance, each modifier is specialized to tackle specific environmental challenges effectively.

3) Is OEM service available for your products?
