Self-Adhesive Bitumen Waterproofing Membrane
 |
【Product Description】 Zhongtong® self-adhesive bitumen waterproofing membrane is a flexible waterproofing system combining SBS elastomeric modified bitumen and PE film or aluminum foil on the upper surface, or no film covered but self-adhesive on both sides. The outer surface is coated removable silicon-coated film or silicon-coated buckle paper as anti-sticking isolation material. The product meets the industry standard GBT23260-2009 “self-adhesive plastic bitumen waterproofing membrane”. |

【Types and Specification】
● Types
-According to the material of upper surface, it can be classified into polyethylene film type (PE), aluminum foil type (AL) and non-film (N) type.
- According to the application site, it can be classified into three types used in exposed waterproof project, non-exposed waterproof project, assistant waterproof project respectively.
【Advantage】
● Self-adhesion: it adheres to the substrate by itself and is safe and environmental friendly.
● Excellent flexibility and extensibility and is adaptable to substrate shrinkage and crack deformation.
● Self-curing: It has ability to automatically cure its fine crack caused by perforated pinhole or stress.
● Excellent adhesive air-tightness. The joint of membrane can adhere and airproof by itself. The joint of membrane has the same long life as the material itself.
【Typical Application】
Self-adhesive membrane polyethylene film on the upper surface can be applied to non-exposed roof of all kinds of architecture, subterranean and indoor project, and can be applied to the waterproof project of engineering such as open-cut subway, tunnel, pool, and aqueduct. It is especially applicable to the engineering whose construction is prohibited to use naked fire.
Self-adhesive membrane aluminum foil on the upper surface can be applied to waterproof project of exposed structure of all kinds of architecture.
Self-adhesive membrane on two sides can be applied only to assistant waterproof engineering, but also to the adhesion and airtightness of the layer joint between two incompatible materials.
【How to Apply】
Please refer to the construction method of self-adhesive waterproofing membrane system.
【Packaging, Storage and Transportation】
● Packaging---It should be packed in plastic bags to be a coil or in cartons.
● Storage and transportation---Light and ran should be prevented from access. Also it should be ventilated. The storage temperature should no higher than 50℃ and it should stand when be stored. The height should be less than two layers. If packed in cartons, the height should not exceed 5 layers.
