Rail transit is a massive and sophisticated systemic project within infrastructure construction, and its quality and safety are deeply embedded in every detail of its defenses. In tunnel construction, the waterproofing system is a crucial "lifeline," carrying a single leak that can disrupt the entire artery.
Zhuobao Technology uses innovative technology research and development as its engine and high-quality product materials as its cornerstone, and has won a number of authoritative certifications in the field of overseas tunnel waterproofing. This not only marks the first time that Chinese waterproofing materials have reached European standards in extreme tests such as compressive strength, joint sealing, and full life cycle durability, but also builds a "zero leakage" technical shield for overseas tunnel engineering waterproofing , and has won the recognition and trust of global customers with its stable and reliable performance.
01
International certification: Demonstrating strength under strict standards
It is understood that overseas tunnel designs generally refer to European EN standards. This market has long been monopolized by international brands, forcing major Chinese tunnel contractors to purchase expensive tunnel waterproofing membranes based on original designs. Zhuobao, with over five years of experience in the overseas tunnel market, has established advantages in product quality, international certifications, project cases covering Asia, South America, and Europe, and professional sets of technical specifications, thus building core competitiveness.
In recent years, the waterproof membranes provided by Zhuobao Technology for overseas tunnel projects have obtained multiple European standard certifications, including:
●2mmPVC European standard tunnel-specific waterproof membrane (certified by a well-known Vietnamese tunnel general contractor and the Vietnam National Laboratory) ●2mmHDPE European standard tunnel-specific waterproof membrane (certified by China Railway Tunnel Bureau Georgia Company and the Turkish National Laboratory); ●2.5mmPVC composite 500g/㎡ geotextile high-end waterproof membrane passed the BV authoritative test (Zhuobao Technology Overseas Department jointly obtained certification with BV professional laboratory); ●The entire product line has obtained DIN EN 13491:2018 (geosynthetics barriers required for the construction of tunnels and related underground structures) property certification (Zhuobao Technology Overseas Department jointly obtained certification with a third-party CE certification professional organization).

Amid increasingly stringent international market access standards, European certification has become a globally recognized benchmark for quality due to its high standards for product performance and technical specifications. Zhuobao Technology's successful certification of multiple European standards not only demonstrates its innovative strength in the development of high-quality waterproofing systems, but also provides authoritative endorsement for its global tunnel engineering collaborations.

Project escort: Global cases witness reliable quality
The tunnel environment is complex and special, and is affected by multiple factors such as groundwater erosion, soil pressure, and temperature changes for a long time. This places extremely high demands on the construction plan, construction environment, and the performance of waterproof materials. Strict indicators are set in multiple dimensions to ensure that the tunnel project can function stably and long-term under extreme conditions, ensure the safety of the tunnel structure, and avoid disasters such as leakage.
Zhuobao Technology, with its leading technological R&D capabilities and system solution capabilities, has firmly established itself as a core player in numerous major tunnel projects. From efficient product supply to professional guidance throughout the entire construction process, Zhuobao Technology has earned widespread recognition and deep trust from clients both domestically and internationally, making it the preferred choice for collaboration on numerous key projects.
Today, Zhuobao's presence can be found everywhere in the global tunnel construction landscape: whether it is the double-track railway tunnel in Thailand connecting regional transportation, or the Gudauri Tunnel and the modern railway T9 tunnel in the North-South Corridor of Georgia that challenge complex geological conditions, or the Vietnam tunnel that supports infrastructure upgrades, as well as the Machu Picchu Tunnel Project in Peru and the Nanjing Jiuhuashan Tunnel, a domestic urban transportation hub , etc. These projects have maintained excellent waterproof conditions after being put into use, and their actual performance has confirmed the hard-core quality of Zhuobao products and their rich global engineering application experience.
03 Innovative technology: Deeply cultivating the tunnel field and leading industry standards
After more than 20 years of hard work, from domestic to overseas, Zhuobao Technology, as a leader in high-quality waterproofing systems, has achieved fruitful results in domestic technological innovation and industry cultivation: not only has it won more than 600 core national patents, 2 national key new products and 2 FM certified products, but it has also built 4 industry standard laboratories and obtained CNAS certification; at the same time, Zhuobao continues to overcome technical difficulties in overseas tunnel waterproofing, and has obtained European standard certification in the field of innovative technology research and development and material production, laying a solid technical foundation for tunnel waterproofing projects.
In the future, Zhuobao Technology will rely on high-quality waterproofing system solutions and international project experience to "dress" engineering waterproofing with more professional technological innovations and higher-quality products and services, and will unswervingly anchor the goal of "becoming a world-leading green building materials group" to continuously inject Chinese wisdom and strength into overseas tunnel waterproofing.
