Sbs Modified Bitumen Asphalt Membrane Roll Waterproofing Building Membrane

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 are a versatile and straightforward solution for all weather conditions. Once the CHENHUA membranes are applied, they form a seamless, watertight barrier that is securely bonded to the surface.

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.
-4mm x 1m x 10m with PE or sand granular top.

2) What's the fundamental difference between SBS and APP?
-SBS and APP are specialized modifiers designed to enhance membrane performance. SBS modifiers significantly improve the cold resistance of waterproof membranes, making them ideal for chilly environments. Meanwhile, APP modifiers bolster the heat resistance of waterproof membranes. Despite their identical appearances, their functional enhancements differ greatly.

3) Is OEM available?
-Absolutely. We warmly welcome you to explore our OEM services at any time.
Simply provide us with your logo, and we can create a bespoke design for you, or feel free to send us your completed design. We will then print it on PE film and ensure it's elegantly packaged before delivering the goods to your doorstep.
