Product Introduction
Bitumen, widely known as asphalt, is a dense, dark, and highly viscous liquid or semi-solid derived from petroleum. Renowned for its extraordinary waterproofing capabilities, it is extensively used in the construction sector. Bituminous membranes are the go-to choice for waterproofing applications on roofs, basements, underground structures, bridges, and countless other constructions. Predominantly, two main application techniques are employed for bitumen membranes.
One is the Torch-on method, a time-tested approach, and the other is Self-adhesive, offering convenience and ease.
Torch-on bituminous membranes present a versatile and straightforward waterproofing solution adaptable to all weather conditions. When CHENHUA membranes are applied, they form a seamless, watertight barrier, securely bonded to the surface, ensuring lasting protection and reliability.

Torch Down Bitumen Waterproof Membranes are widely used across various building grades for waterproofing and seepage-proofing projects. Suitable for both exposed and concealed areas, these versatile membranes excel in flat roofs, sloped roofs, underground spaces, tunnels, bridges, parking lots, reservoirs, and beyond.
Application method:
1. Substrate:
Ensure that the substrate is immaculately clean, dry, and free from contaminants, prepared to perfection for optimal adhesion.
All dust and loose, friable materials must be thoroughly eliminated.
Blowholes and voids should be fully exposed and meticulously repaired.
2. Primer:
Apply primer before laying the membrane. Clean the substrate meticulously with a dust catcher or blower, then coat it thoroughly with a primer to ensure waterproofing, effective dust consolidation, and enhanced adhesion.
3. Membrane placement:
*Carefully unroll the torch-on membrane, aligning it precisely before starting the torching or bonding process.
*Each membrane must be laid in parallel, staggered by at least 1 meter to prevent coinciding joints, ensuring a seamless finish.
*The end-to-end overlaps must be alternated, never positioned along a single line to maintain structural integrity.
*Always commence at the lowest slope height, starting with drains, downpipes, or other critical details.
*During torching, apply heat to both the membrane and the substrate simultaneously, focusing on the roll and overlapping areas for perfect adhesion.
*Overlaps must be welded with precision, ensuring a thin trickle of melted mixture, approximately 1 cm wide, visibly appears along the overlap line for complete waterproofing.
4.Utilize a roller to firmly press down the membrane surface, ensuring a secure and lasting adhesion.
Attention:
1. Ensure the substrate is dry and clean. Avoid working on rainy or snowy days to maintain installation integrity.
2. Refrain from working in heavy winds (above grade 5) to ensure safety and quality.
3. Not suitable for construction below 5°C to prevent material brittleness.
4. If rain or snow occurs during construction, protective measures for the laid membrane are essential to prevent damage.
5. All personnel must wear special safety uniforms during installation. Fire control equipment is essential for safety.

Packing and shipping:
1. Store membranes in a dry, well-ventilated environment to maintain their quality.
2. Different membrane types must be stored separately to prevent cross-contamination.
3. Under normal conditions, the storage period is one year from the production date, ensuring long-lasting quality.
4. Membrane rolls should be stored vertically during transportation and shielded from sunlight and rain to prevent damage.

1) What's the popular size for Torch-on bitumen membrane?
-The favored size is 3mm x 1m x 10m, available with a PE or sand granular top for varied applications.
-Dimensions: 4mm x 1m x 10m, featuring a top layer available in PE film or sand granular finish, offering versatility and adaptability.
2) What's the fundamental difference between SBS and APP?
-SBS and APP are high-performance modifiers crafted to elevate membrane durability and efficiency. SBS (Styrene-Butadiene-Styrene) modifiers are renowned for their superior enhancement of cold resistance, making them a stellar choice for frigid climates. On the other hand, APP (Atactic Polypropylene) modifiers are lauded for their exceptional heat resistance, ideal for hotter conditions. Although they share a similar aesthetic, the functionalities they augment are distinctively tailored to their respective climatic challenges.
3) Is OEM available?
-Absolutely! We extend a warm invitation to you to explore our comprehensive OEM services, available at your convenience.
Simply provide us with your logo, and we can craft a bespoke design tailored to your specifications, or feel free to submit your completed design. We will print it on PE film with precision and package it beautifully, ensuring a seamless delivery to your location.
4) Are you a factory?
-Indeed, Shandong Chenhua Waterproof Co., Ltd. stands as a seasoned expert in the production of a wide range of waterproof materials, having specialized in the field since 1994. Nestled in the iconic China Waterproof Town-Taitou, our factory delivers an extensive array of products catering to both concealed and exposed waterproofing applications, ensuring robust protection tailored to every need.
5) What is the delivery time?
-Typically, once an order is confirmed, it reaches completion within a streamlined period of 10 days. However, please be aware that delivery times might adjust based on unique project specifications and order volumes, ensuring optimal fulfillment.
