What is the resistance type SBS waterproofing membrane?
There are three main principles of root-resistant puncture waterproofing membrane:
The first is a physical resistance to the beam with the piercing strength as a resistance method.
The second is chemical resistance, in the waterproofing membrane production process, adding chemical resistance agent, similar to the chemical composition of herbicides, the plant roots are not close to the waterproofing membrane; In addition, copper ions have a similar effect.
The third is the combination of the above two principles.
SBS resistant root puncture membrane has three kinds:
1, composite copper fetal base SBS modified asphalt waterproofing membrane. Mainly using copper tires to puncture strength, while copper ion drive plant roots.
2, copper foil tire SBS modified asphalt waterproofing membrane. Mainly the use of copper ion drive plant roots, while a certain anti-piercing strength.
3, SBS modified asphalt root resistant puncture waterproofing membrane. Mainly chemical resistance to root.
