Product Description

Product Introduction

 

Discover the exquisite art of waterproofing with Bitumen, a dense, black, and highly viscous liquid or semi-solid derived from the finest petroleum. Renowned for its unparalleled waterproofing ability, Bitumen is a cornerstone in the construction industry. Our bituminous membranes are unrivaled for waterproofing applications, perfectly suited for roofs, basements, underground structures, bridges, and various other constructions. Among the many ways to apply bitumen membranes, two techniques stand out prominently.
The Torch-on method and the Self-adhesive application are your go-to techniques.
Torch-on bituminous membranes offer a versatile and simple solution for all weather conditions. Once the prestigious CHENHUA membranes are applied, they create a seamless and watertight barrier that fuses securely with the surface, ensuring reliable protection.

Torch Down Bitumen Waterproof Membranes are the go-to choice across a multitude of building grades for waterproofing and seepage-proofing projects. They are perfect for both exposed and hidden areas such as flat roofs, sloped roofs, underground spaces, tunnels, bridges, parking lots, reservoirs, and much more.

Application Method:
1. Substrate:
Ensure the substrate is impeccably clean, dry, and free from all contaminants, achieving a state of perfection.
Eliminate all dust and loose, friable materials with precision.
Expose and repair all blowholes and voids completely.
2. Primer:
Apply primer meticulously before laying the membrane. Clean the substrate using a dust catcher or blower, then coat it generously with a treatment primer to ensure optimal waterproofing, enhancing dust consolidation and adhesion.
3. Membrane Placement:
*Unroll the torch-on membrane with care, aligning it precisely before beginning the torching or bonding process.
*Lay each membrane in parallel, staggered by at least 1 meter to avoid coinciding joints for optimal results.
*Alternate end-to-end overlaps, ensuring they are never placed along a single line.
*Begin at the lowest slope height, focusing on areas with drains, downpipes, or other details.
*During torching, heat both the membrane and substrate concurrently, particularly focusing on the roll and overlapping areas for a flawless finish.
*Ensure overlaps are meticulously welded, creating a delicate stream of melted mixture, about 1 cm wide, along the overlap line.
4.Use a roller to firmly press down the membrane surface, ensuring secure adhesion.


Attention:
1. Confirm the substrate is dry and pristine. Avoid operations on rainy or snowy days.
2. Avoid working in strong winds (above grade 5) to ensure safety.
3. Construction is not recommended below 5°C for optimal performance.
4. In the event of rain or snow during construction, protective measures for the laid membrane are crucial.
5. Safety is paramount; ensure all personnel wear appropriate uniforms during installation. Fire control equipment is mandatory.


Packing and Shipping:
1. Store membranes in dry, well-ventilated spaces for optimal preservation.
2. Different membrane types must be stored separately to maintain integrity.
3. Under typical conditions, the storage period extends to one year from the production date.
4. Store membrane rolls vertically during transit, and shield them from sunlight and rain for pristine condition.

1) What is the popular size for the Torch-on bitumen membrane?
-3mm x 1m x 10m with a choice of PE or sand granular top.
Experience the premium quality of our membrane: a robust 4mm thick, 1m wide, and 10m long, featuring an elegant PE or sand granular top finish.

2) What's the fundamental difference between SBS and APP?
Delve into the science of waterproofing with SBS and APP modifiers. While both enhance membrane performance, SBS dramatically boosts cold resistance, perfect for frigid conditions. On the other hand, APP significantly elevates heat resistance, ensuring durability in warmer settings. Visually similar, yet functionally diverse, they cater to distinct environmental needs.

3) Is OEM available?
Indeed! We wholeheartedly invite you to explore our flexible and personalized OEM services, always at your convenience.
Simply present us with your logo, and we will craft a unique design tailored to your brand. Alternatively, provide your existing design, which we'll elegantly print on PE film. Rest assured, each product is meticulously packaged and promptly delivered to your doorstep.
