Self-Adhesive Sheet
What is a self-adhesive waterproof sheet?
Self-adhesive waterproof sheet with stable adhesion and durability
Self-adhesive waterproofing sheets must adhere stably to the substrate and continuously maintain their adhesive strength even in various field environments.
Excellent initial adhesion
Long-term stable adhesion
Minimizing sagging during wall construction in summer
Maintains stable self-adhesion even after water level rises
High durability
Construction is possible even in low-temperature environments.
Eco-friendly product composition
SMC-100 Product Structure
Multilayer structure for stable waterproof performance
01
HDPE + LDPE double-sided cross film
Adhesion is enhanced with a composite film that adjusts surface tension.
02
Self-adhesive waterproofing layer
We enhanced adhesion to the substrate by applying a high-adhesion, high-durability asphalt compound.
03
SMC Exclusive Primer
This is a dedicated primer system that can be applied according to site conditions.
04
concrete sphere
It is a structure in which the waterproofing layer adheres stably to the structure.

SMC-100 Product Features
Self-adhesive asphalt waterproofing sheets meeting or exceeding KS F 4934 : 2008 standards
Unlike existing improved asphalt sheets that are constructed using torches, burners, etc., SMC-100 does not heat, so there is no risk of fire and can be easily constructed using only its own adhesive, making it eco-friendly.
self-adhesive
- Enhanced adhesion with composite HDPE film with adjusted surface tension
- Increased adhesion to substrate with high-adhesion, high-durability asphalt compound
Cold and heat resistance
- Construction is possible at -7℃ (for winter) No cracks occur even at -20℃
- There are almost no symptoms such as bleeding when backfilling is delayed in summer
adhesive
- The world’s highest level of adhesion provides excellent sheet-to-sheet overlap, bending area, and behavioral response, and the adhesion performance of the entire sheet is excellent, enabling close adhesion to the structure
durability
- Product properties are maintained stably even in tests that are harsher than reality
- Underwater immersion (9 hours) -20℃ ➞ 50℃ repeated 10 times, salt water immersion for more than 168 hours
No harmful substances
- Constructed only from eco-friendly raw materials
- Satisfies RoHS standards, a directive on the use of hazardous substances specified by the European Union (EU)
Excellent constructability
SMC-100 is faster, safer, and has a simpler process, drastically reducing the risk of defects.
wet application
- When the substrate is wet, construction can be done immediately without drying, unlike existing waterproofing materials
- When the moisture content of the substrate is less than 14.4%, apply SMC-SUPER primer before construction
pliability
- When cracks occur due to sagging of the substrate or water expansion, SMC-100 has excellent behavioral response
Defect prevention - The sheet is flexible, making it easy to construct complex shaped areas or corners
Non-overlapping joint
The non-overlap method eliminates height differences at the sheet connection points, ensuring watertightness, adhesion, and durability of the overlap area.
