Characteristics of Waterproofing Membrane
1. SBS modified bitumen compound
|
• Tensile strength and elongation
• Fatigue resistance against repeated expansion and contraction of structure
• Flexibility at low temperature
• Heat-resistance
• Elasticity and restoring force. |
|
|
|
2. Good durability and shape stability |
|
Kukdong membranes have on excellent durability and shape stability, with non-woven polyester reinforcement. |
|
|
|
3.Excellent cold-resistance and heat-resistance |
|
Kukdong waterproofing membranes can be applied in various weather conditions from mild region to cold region. |
|
|
|
4. No deterioration by torch-on |
|
There is no physical deterioration when the membrane applied with torch since it has excellent heat-resistance. |
|
|
|
5. Excellent installability and watertightness |
|
We have greatly improved the adhesive force of self-adhesive membrane, so that our membranes have achieved excellent install ability and watertightness of over-lap joints. |
