As a grand and precise system project in infrastructure construction, the quality and safety of rail transit are deeply rooted in every minute defense line. In the construction of tunnel transportation projects, the waterproofing system is a "lifeline" that bears a heavy responsibility. A single leakage can be enough to disrupt the entire artery. 

Joaboa Tech, with its innovative technology research and development as the driving force and high-quality product materials as the foundation, has won multiple authoritative certifications in the overseas tunnel waterproofing field. This not only marks the first time that Chinese waterproofing materials have reached European standards in extreme tests such as compressive strength, joint sealing performance, and full life cycle durability, but also builds a "zero leakage" technical shield for overseas tunnel engineering waterproofing. With its stable and reliable performance, it has won the recognition and trust of global customers. 

01 International Certification: Demonstrating Strength under Stringent Standards 

It is understood that overseas tunnel design generally follows the European EN standards. This market has long been monopolized by international brands, forcing Chinese tunnel general contractors going global to purchase expensive tunnel waterproofing membranes based on the original design. Now, with over five years of in-depth experience in the overseas tunnel market, joaboa has established advantages in product quality, international certifications, engineering cases covering Asia, South America and Europe, as well as professional and complete technical bid documents, thus forging its core competitiveness.

In recent years, the waterproofing membranes provided by joaboa tech for overseas tunnel projects have obtained multiple European standards certifications, including: 

● 2mm PVC European standard tunnel-specific waterproofing membrane (certified by a well-known Vietnamese tunnel general contractor in collaboration with the Vietnamese National Laboratory)
● 2mm HDPE European standard tunnel-specific waterproofing membrane (certified by China Railway Tunnel Bureau Georgia Company in collaboration with the Turkish National Laboratory)
● 2.5mm PVC composite 500g/㎡ geotextile high-end waterproofing membrane passed BV authoritative testing (certified by joaboa tech Overseas Department in collaboration with BV professional laboratory)
● All products have obtained the characteristic certification of DIN EN 13491:2018 (required for geosynthetic barriers used in the construction of tunnels and related underground structures) (certified by joaboa tech Overseas Department in collaboration with a third-party CE certification professional institution)

CE Certificate

Against the backdrop of increasingly strict international market access standards, the European standard certification, with its high requirements for product performance and technical specifications, has become a globally recognized quality benchmark. Joaboa Tech's successful acquisition of multiple European standard certifications not only highlights its innovative strength in the research and development of high-quality waterproofing systems but also provides authoritative endorsement for its global tunnel engineering cooperation. 

02 Project Escort: Global Cases Bear Witness to Reliable Quality 

The tunnel environment is complex and special. It is constantly affected by various factors such as groundwater erosion, soil pressure, and alternating temperature changes. This places extremely high demands on the construction plan, construction environment, and performance of waterproof materials. Strict standards have been set in multiple dimensions to ensure that the tunnel project can function stably for a long time under extreme conditions, guarantee the safety of the tunnel structure, and prevent disasters such as leakage. 

With its leading technological R&D strength and system solution capabilities, Joaboa Tech has consistently played a core role in numerous major tunnel projects. From efficient product supply to professional guidance throughout the entire construction process, it has won wide recognition and deep trust from both domestic and international clients, making it the preferred partner for many key projects.

To this day, Joaboa's presence can be found all over the global tunnel construction landscape: from the double-track railway tunnel in Thailand that connects regional transportation, to the Gudauri Tunnel and the modern T9 railway tunnel in Georgia that challenge complex geological conditions, to the tunnels in Vietnam that support infrastructure upgrades, as well as the Machu Picchu tunnel project in Peru and the Nanjing Jiuhua Mountain Tunnel, a domestic urban transportation hub. After these projects were put into use, they all maintained excellent waterproofing conditions, which has proven Joaboa's hard-core product quality and rich global engineering application experience through actual performance. 

03 Innovative Technology: Deeply Engaged in the Tunnel Industry, Leading Industry Standards

For over two decades, Joaboa Tech has been forging ahead both domestically and internationally, leading the way with its high-quality waterproofing systems. It has achieved remarkable success in domestic technological innovation and industrial development: not only has it obtained over 600 core national patents, 2 national key new products, and 2 FM certified products, but it has also established 4 industry standard laboratories that have received CNAS certification. At the same time, Joaboa has continuously tackled technical challenges in overseas tunnel waterproofing, obtaining European standards certification in the fields of innovative technology research and development and material production, thus laying a solid technical foundation for tunnel waterproofing projects.

In the future, Joaboa Tech, relying on its high-quality waterproof system solutions and international project experience, will continue to "dress and cap" engineering waterproofing with more professional technological innovation and superior product services. Firmly anchored in the goal of becoming a globally outstanding green building materials group, it will continuously inject Chinese wisdom and strength into overseas tunnel waterproofing.
