Rubberized Asphalt Waterproof Membrane
Description
Technical Parameters
For roof and underground works in low-temperature environments, ordinary bitumen membranes tend to harden, turn brittle and lose bonding force under low temperatures-rubberized asphalt waterproof membrane becomes the preferred option for cold-region and winter construction projects due to superior low-temperature performance delivered via rubber modification. Our rubberized asphalt waterproof membrane takes premium road bitumen as the base material, blended with multiple rubber components including styrene-butadiene rubber and recycled rubber for modification, paired with polyester mat or glass fiber mat reinforcement. The resulting membrane integrates high elasticity of rubber and bonding performance of bitumen, retaining excellent flexibility and adhesion even under low-temperature conditions. The low-temperature flexibility of this rubberized asphalt waterproof membrane reaches -30℃ with no cracking, far superior to ordinary SBS modified bitumen membranes. It also delivers certain self-healing performance to automatically seal small puncture damage, ideal for northern cold regions and building structures with minor deformation. This rubberized asphalt waterproof membrane has been deployed in multiple roof and basement projects in cold northern and northwestern regions of China, maintaining stable waterproof performance after enduring multiple cold winters.
We optimize rubber component ratios and vulcanization processes in the formula to ensure full fusion between rubber particles and bitumen, eliminating delamination and segregation common to ordinary rubberized asphalt membranes. The product line covers two series: torch-on variants suitable for large-area roof and underground works, and self-adhesive variants for indoor spaces and open-flame-prohibited scenarios, enabling flexible selection per construction conditions. Compared with ordinary SBS membranes, rubberized asphalt waterproof membrane boasts higher elastic recovery rates to better adapt to thermal expansion, contraction and minor settlement of base layers, reducing leakage risks from fatigue cracking of waterproof layers. For agents, this product highlights differentiated selling points of low-temperature performance and high elasticity, delivering strong competitiveness in cold-region markets to help you avoid homogenized price wars and secure more mid-to-high-end projects.

Quality Control
Our quality control focus for rubberized asphalt waterproof membrane lies in rubber modification effects and low-temperature performance. Every batch of raw rubber and bitumen undergoes testing of rubber purity, bitumen penetration and softening point to guarantee stable quality of modified base materials. During production, we strictly control grinding passes of colloid mills and modification temperatures to ensure fine and uniform dispersion of rubber particles within bitumen, eliminating caking and segregation phenomena. Low-temperature flexibility testing is mandatory for finished products before delivery: samples are placed in a -30℃ cryostat for 2 hours and bent with no cracking permitted for qualification, alongside testing of tensile strength, elongation, water impermeability and heat resistance for core indicators. We have established a complete quality traceability system, with every roll assigned a unique batch number traceable to raw material sources, production time and testing records. On-site inspection by third-party institutions is supported, with complete quality inspection reports delivered alongside all goods. Within the 1-year warranty period, we take full responsibility for any quality issues arising from product defects.
Payment Terms
We offer flexible and diversified payment plans adapted to capital demands of clients of all scales. Standard spot orders adopt a settlement method of 30% advance payment + 70% balance payment, with the balance payable against copy of bill of lading to guarantee transaction safety for both parties. Customized product orders adopt 50% advance payment + 50% balance payment, with weekly synchronization of production progress for fully controllable delivery schedules. US dollar telegraphic transfer settlement is supported, and letters of credit can be negotiated for long-term cooperative premium clients to lower capital occupation pressure. Tiered unit price discount systems apply for bulk purchases and annual framework cooperation clients-higher purchase volumes correspond to stronger unit price concessions, alongside exclusive benefits including priority production scheduling and free technical support. We adhere to a win-win long-term cooperation philosophy, willing to grow alongside agents to jointly develop local markets.
