Sbs Modified Bitumen Membrane
Description
Technical Parameters
Our factory is located in Dingzhou, China. We have over 12 years of manufacturing experience, with a 16,000㎡ production facility and an in-house laboratory team.
We have supplied SBS modified bitumen membrane to major contractors such as China State Construction and China Railway. These companies have very strict quality standards and conducted thorough inspections of our products. The membranes passed all required tests, proving their reliability for demanding construction projects.
How This SBS Modified Bitumen Membrane Prevents Water Leakage and Adapts to Structural Movement
We start with a reinforced base layer made of polyester or fiberglass mat. SBS rubber is then added to the bitumen, improving flexibility while maintaining strength.
The surface is finished with PE film, aluminum foil, or other protective materials.
This SBS modified bitumen membrane provides excellent waterproofing performance. It forms a continuous barrier against water penetration while maintaining high elasticity. When a building experiences slight movement or cracking, the membrane can stretch accordingly without tearing.
It performs well in both extremely cold and hot climates, which is why it is widely used in northern construction regions.
Factory Test Data and Simple Warranty Policy
We operate under the ISO9001 quality management system and inspect every production batch.
