Torch-applied Modified Bitumen Membrane
Description
Technical Parameters
In the field of underground engineering and roof waterproofing, the reliability of torch-on construction is a well-recognized consensus across the industry. Our torch-applied modified bitumen membrane adopts long-fiber polyester mat as the reinforcing substrate, coated with SBS modified bitumen mixture, and covered with separating materials on both sides. After 12 years of process iteration and verification in over 500 engineering projects, a stable product performance system has been formed. This torch-applied modified bitumen membrane is especially suitable for scenarios requiring high durability of waterproof layers, such as concrete roofs, basement base slabs, and tunnel linings. The torch-fused lap joints form an integrated sealing layer, fundamentally eliminating the risk of water channeling. Among our clients are subway projects under China State Construction, bridge projects of China Railway Group, as well as commercial real estate projects for overseas purchasers.
The core reason they choose us is straightforward: at the same price range, our soluble matter content is 15% higher than the industry standard, and low-temperature flexibility reaches -25℃ without cracking.
Unlike some manufacturers in the market that cut corners by reducing the thickness of the coating layer, our factory implements a "three-inspection system" for every batch of torch-applied modified bitumen membrane: raw material incoming inspection, in-process patrol inspection, and 100% finished product inspection. Within our 16,000 ㎡ production base, 3 automated production lines deliver a monthly output of 500,000 ㎡, with standard-specification products available for delivery within one week. We fully understand overseas clients' sensitivity to delivery schedules, so we always maintain a 30-day safety stock of raw materials to guarantee on-time shipment even during peak seasons. For agents, this means no anxiety about delivery times and no rework due to poor quality-every roll can be directly laid on construction sites.

Factory Strength
We are a source manufacturer with 12 years of experience in waterproof building material production, covering a plant area of 16,000 ㎡, equipped with 3 automated waterproof membrane production lines and 2 coating production lines, achieving a monthly output of 500,000 ㎡ waterproof membranes and 200 tons of waterproof coatings. We maintain long-term strategic cooperation with Fortune Global 500 enterprises including China State Construction Group, China Railway Group, China Railway Construction Corporation and China Communications Construction Company, and our products are widely applied in national key projects such as subways, high-speed railways and bridges. The factory has an independent R&D team that continuously invests in formula optimization and process improvement to ensure all products keep pace with the technical rhythm of the international market. For overseas agents, partnering with us means gaining a reliable supply chain partner with guaranteed production capacity, technical support and verified engineering case endorsements.
Quality Control
We have obtained ISO9001 quality management system certification and established a full-process quality traceability system from raw material incoming to finished product outbound. Every batch of membrane undergoes 100% visual inspection and sampling performance testing before delivery, covering key indicators such as thickness deviation, tensile strength, elongation, low-temperature flexibility and water impermeability. We voluntarily accept on-site testing by third-party inspection bodies, including internationally renowned institutions SGS and BV. All delivered products come with complete quality inspection reports and product certificates to reassure your end clients. Within the 1-year warranty period, we promise to respond within 24 hours and provide a solution within 48 hours if any product quality issues arise.
After-Sales Service
Our service extends far beyond shipment. From the moment you send an inquiry, a dedicated account manager will follow up throughout the whole process: pre-sales provision of technical scheme matching and sample delivery services; mid-sales synchronization of production progress photos and videos, with photos taken during container loading to ensure intact goods shipment; proactive reminders before goods arrive at the port and assistance in preparing customs clearance documents. During construction, our technical team can provide remote guidance and develop special construction schemes for complex joints. Regular post-delivery follow-ups are conducted to collect project feedback for continuous product optimization. We firmly believe high-quality products paired with comprehensive service will help your business grow steadily.
