Product Description

Product Introduction

 

Bitumen, often recognized as asphalt, is a dense, black, and highly viscous liquid or semi-solid derived from petroleum. Celebrated for its remarkable waterproofing properties, it is extensively utilized in the construction industry. Bituminous membranes are ideal for waterproofing applications on roofs, basements, underground structures, bridges, and many other constructions. Predominantly, there are two main application techniques for bitumen membranes.
One is the Torch-on method, and the other is Self-adhesive.
Torch-on bituminous membranes offer an adaptable and efficient waterproofing method suitable for any weather condition. Once the CHENHUA membranes are expertly applied, they create a flawless, watertight barrier that adheres securely to the surface, ensuring exceptional performance.

Torch Down Bitumen Waterproof Membranes are extensively used across various building grades for waterproofing and seepage-proofing projects. Suitable for both exposed and concealed areas, these include flat roofs, sloped roofs, underground spaces, tunnels, bridges, parking lots, reservoirs, and more.

Application method:
1. Substrate:
Ensure that the substrate is meticulously clean, dry, and free from all forms of contaminants, prepared to perfection.
All dust and loose, friable materials must be thoroughly eradicated.
Blowholes and voids should be completely exposed and subsequently repaired.
2. Primer:
Apply primer before laying the membrane. Clean the substrate with a dust catcher or blower and then coat it thoroughly with a treatment primer to ensure waterproofing, ensuring effective dust consolidation and enhanced adhesion.
3. Membrane placement:
*Carefully unroll the torch-on membrane and align it precisely before initiating torching or bonding.
*Each membrane must be laid in parallel, staggered by at least 1 meter to prevent coinciding joints.
*The end-to-end overlaps must be alternated, never positioned along a single line.
*Always commence at the lowest slope height, starting with drains, downpipes, or other details.
*During torching, heat both the membrane and the substrate simultaneously, focusing on the roll and overlapping areas.
*Overlaps must be welded with precision, ensuring a thin trickle of melted mixture, approximately 1 cm wide, appears along the overlap line.
4.Utilize a roller to firmly press down the membrane surface, guaranteeing a secure adhesion.


Attention:
1. Ensure the substrate is dry and clean. Avoid working on rainy or snowy days.
2. Refrain from working in heavy winds (above grade 5).
3. Not suitable for construction below 5°C.
4. If rain or snow occurs during construction, protective measures for the laid membrane are essential.
5. All personnel must wear special uniforms for safety during installation. Fire control equipment is essential.


Packing and shipping:
1. Store membranes in dry, well-ventilated conditions.
2. Different membrane types must be stored separately.
3. Under normal conditions, the storage period is one year from the production date.
4. Membrane rolls should be stored vertically during transportation and be protected from sunlight and rain.

1) What's the popular size for Torch-on bitumen membrane?
-3mm x 1m x 10m with PE or sand granular top.
-Unveil the robust 4mm thickness membrane, measuring 1m in width and 10m in length, available with a sleek PE film or a textured sand granular top for superior surface protection.

2) What's the fundamental difference between SBS and APP?
-SBS and APP are expertly crafted modifiers, each tailored to elevate membrane capabilities. SBS modifiers are engineered to dramatically enhance the cold resistance of waterproof membranes, making them the perfect choice for frigid climates. Conversely, APP modifiers are formulated to augment heat resistance, ensuring longevity in warmer conditions. While these modifiers share a similar look, their performance enhancements are uniquely different.

3) Is OEM available?
-Absolutely. We extend a warm invitation for you to engage with our comprehensive OEM services at your convenience.
Provide us with your distinctive logo, and we will craft a personalized design for you. Alternatively, share your finalized design, and we will meticulously print it onto PE film, ensuring the final product is elegantly packaged and delivered promptly to your location.
