Composite Waterproofing Membrane Made with Recycled Materials
Turbo Sheet GTR3000

An integrated composite waterproofing membrane combining a high-adhesion flexible gel made with recycled materials and a waterproofing sheet, providing reliable waterproofing performance and improved installation efficiency.

Registered as an excellent product by the Public Procurement Service, making it available for purchase without competitive bidding.

Features (Patent No. 10-2551933)

High tack and flexibility provide excellent adhesion, even on irregular, wet, or underwater surfaces.
Excellent flexibility accommodates structural movement and helps prevent cracking, delamination, and membrane lifting.
Self-adhesive installation eliminates heat-fusion processes, reducing installation time and labor requirements.
Incorporates recycled materials to support more sustainable construction.

1. Easy installation

2. Reduced construction time

3. Cost-effective construction

High adhesive strength

Existing technology

GTR3000

“Effect of manifesting adhesive and sealing properties in low-temperature winter environments through improved temperature resistance”

High flexibility

Existing technology

GTR3000

“Due to the high flexibility of the structural behavior, problems such as cracking or sagging of the waterproofing layer do not occur.”

Resistance to sagging

Existing technology

GTR3000

“Securing sagging resistance through improved heat resistance. Antioxidant properties due to a composite structure in which a waterproof sheet layer is formed on the upper surface of the adhesive layer.”

Eco-friendly certification

Benefits of Using Eco-Friendly Products in Public Procurement

Local governments across Korea, including the Seoul Metropolitan Government, prioritize products certified with the Environmental Mark through green procurement policies and public construction specifications.

Green Product Procurement by Public Institutions

Legal Basis: Article 6 of the Act on the Promotion of Purchase of Green Products

Public institutions are required to purchase certified green products, including products with the Environmental Mark, when such products are available for the items being procured.
Exceptions may apply in certain circumstances, such as when product quality or availability does not meet procurement requirements, other priority procurement obligations apply, or urgent procurement is required.
