Product Description

Product Introduction

 

Bitumen is a revered material in the construction world, known as asphalt, with its dense, black, and highly viscous nature derived from petroleum. This extraordinary waterproofing agent is celebrated for its superior performance, making it indispensable across the construction sector. The bituminous membranes offer an ideal solution for comprehensive waterproofing, extending their protective reach from roofs to basements and underground structures, including bridges and various other constructions. There are primarily two distinguished application techniques for these durable bitumen membranes.
The first is the renowned Torch-on method, a classic choice for many, while the second is the innovative Self-adhesive approach.
Torch-on bituminous membranes stand as your ultimate solution for any weather scenario, offering both versatility and simplicity. When CHENHUA membranes are expertly applied, they transform into a seamless, watertight barrier intimately bonded to the surface, ensuring unmatched protection and performance.

Torch Down Bitumen Waterproof Membranes are the preferred choice for waterproofing and seepage-proofing across a wide array of building grades. Whether for exposed or concealed areas, these resilient membranes excel in securing flat roofs, sloped roofs, underground spaces, tunnels, bridges, parking lots, reservoirs, and much more.

Application method:
1. Substrate:
Ensure that the substrate is perfectly clean, dry, and free from contaminants, setting the stage for an impeccable application.
All dust, along with any loose and friable materials, must be meticulously removed to ensure a pristine surface.
Blowholes and voids should be fully exposed and expertly repaired thereafter to create an ideal surface.
2. Primer:
Before placing the membrane, apply primer meticulously. Clean the substrate using a dust catcher or blower, then coat it with a treatment primer to enhance waterproofing, ensuring effective dust consolidation and superior adhesion.
3. Membrane placement:
*Unroll the torch-on membrane with precision, aligning it accurately before beginning the torching or bonding process.
*Lay each membrane in parallel, ensuring they are staggered by at least 1 meter to avoid coinciding joints for optimal stability and performance.
*Alternating the end-to-end overlaps is crucial, avoiding alignment along a single line for enhanced structural integrity.
*Always initiate at the lowest slope height, prioritizing drains, downpipes, or other critical details for superior outcomes.
*During the torching process, simultaneously heat both the membrane and substrate, focusing on the roll and overlapping areas for a secure and enduring bond.
*Precisely weld overlaps to ensure a clean trickle of melted mixture, about 1 cm wide, along the overlap line for a flawless finish.
4.Employ a roller to firmly compress the membrane surface, ensuring an impeccable adhesion that stands the test of time and elements.


Attention:
1. The substrate must be dry and clean. For optimal results, work should be avoided on rainy or snowy days.
2. Avoid working in winds stronger than grade 5 to ensure both safety and quality.
3. Construction should not proceed if the temperature is below 5°C to avoid compromising the integrity of the work.
4. If rain or snow ensues during construction, protective measures for the laid membrane are crucial to maintain its quality and effectiveness.
5. All personnel must wear designated safety uniforms, and fire control equipment is a mandatory requirement during installation for utmost safety.


Packing and shipping:
1. Store membranes in a dry, well-ventilated environment to preserve their quality and longevity.
2. Different types of membranes should be stored separately to prevent mixing and ensure optimal performance.
3. Under optimal conditions, the storage duration is one year from the date of production, ensuring reliability when needed.
4. During transportation, membrane rolls should be stored vertically and shielded from sunlight and rain to maintain their condition.
