Turbo Seat GTR
A self-adhesive sheet integrating eco-friendly, high-adhesion recycled rubber and a membrane sheet, serving as a waterproofing material that adheres to concrete surfaces using the stickiness of an adhesive gel without the application of primer or heat.
Pre-GTR reverse casting waterproofing sheet
A composite sheet integrating a water-reactive polymer coating material capable of reverse casting and a membrane sheet, serving as a waterproofing material capable of integrated adhesion to the poured concrete.
GTR GEL / GTR GEL S
A composite sheet integrating a water-reactive polymer coating material capable of reverse casting and a membrane sheet, serving as a waterproofing material capable of integrated adhesion to the poured concrete.
