Product Description

Product Introduction

 

Bitumen, a renowned component often synonymous with asphalt, is a dense, black, and highly viscous liquid or semi-solid extracted from petroleum. Its extraordinary waterproofing capabilities make it an indispensable material in the construction sector. Bituminous membranes stand as the premier choice for waterproofing applications across roofs, basements, underground structures, bridges, and numerous other edifices. There are primarily two sophisticated methods to apply these bitumen membranes.
These are the innovative Torch-on method and the efficient Self-adhesive technique.
Torch-on bituminous membranes offer a dynamic and uncomplicated waterproofing solution suitable for all weather scenarios. Once CHENHUA membranes are expertly installed, they create a seamless, watertight barrier that is firmly bonded to the substrate, ensuring enduring protection.

Torch Down Bitumen Waterproof Membranes find extensive application in a plethora of building grades, providing foolproof waterproofing and seepage-proofing solutions. They are ideal for both exposed and concealed environments, including flat roofs, sloped roofs, subterranean areas, tunnels, bridges, parking areas, reservoirs, and beyond.

Application method:
1. Substrate:
Ensure the substrate is meticulously pristine, impeccably dry, and devoid of any contaminants, prepared for ultimate adhesion.
All dust and loose, friable particulates must be thoroughly removed.
Expose and repair all blowholes and voids to ensure a flawless surface.
2. Primer:
Apply primer before membrane installation. Clean the substrate with a dust catcher or blower and apply a comprehensive treatment primer for optimal waterproofing, enhancing dust consolidation and adhesion.
3. Membrane placement:
*Unroll the torch-on membrane with care, aligning it with precision before commencing torching or bonding.
*Lay each membrane in parallel, ensuring a staggering of at least 1 meter to avoid coinciding joints.
*Alternate end-to-end overlaps, avoiding alignment along a single line.
*Initiate from the lowest slope height, beginning with drains, downpipes, or other specifics.
*During torching, simultaneously heat the membrane and substrate, focusing on roll and overlap areas for optimal bonding.
*Ensure overlaps are precisely welded, with a thin trickle of melted material, approximately 1 cm wide, along the overlap.
4.Employ a roller to apply firm pressure on the membrane surface, ensuring robust adhesion.


Attention:
1. Confirm the substrate is dry and clean. Avoid operations on rainy or snowy days.
2. Refrain from working in strong winds (above grade 5).
3. Not advisable for conditions below 5°C.
4. In the event of rain or snow during construction, implement protective measures for the installed membrane.
5. All workers must wear specialized uniforms for safety during installation. Fire control equipment is mandatory.


Packing and shipping:
1. Store membranes in a dry, well-ventilated environment.
2. Different membrane types should be stored separately to maintain quality.
3. Under standard conditions, storage duration is one year from the production date.
4. During transportation, store membrane rolls vertically and shield them from sunlight and rain.

1) What's the popular size for Torch-on bitumen membrane?
-3mm x 1m x 10m featuring PE or sand granular top for added texture and durability.
-4mm x 1m x 10m with PE or sand granular top. This standard size ensures robust coverage, and the option of a PE or sand granular top layer offers flexibility and enhanced surface protection for varied waterproofing projects.

2) What's the fundamental difference between SBS and APP? Delve into the unique advantages of each with our expert insights.
-SBS and APP are specialized modifiers meticulously crafted to elevate membrane performance. SBS modifiers considerably enhance the cold resistance of waterproof membranes, a critical feature for frigid environments. Conversely, APP modifiers amplify the heat resistance, safeguarding membranes in high-temperature conditions. Although they appear identical, the performance enhancements they offer are distinctly advantageous.

3) Is OEM available? Discover the possibilities of tailoring our products to fit your brand.
