Maenam High-Tech │ Establishment of Maenam Deep Sea Shield Waterproof Deep-Sea Research Group, Empowering New Deep-Sea Waterproof, Water-Blocking and Water-Retaining Technologies

At present, China is accelerating the deployment of key fields such as deep-sea scientific research, marine energy, and ocean engineering infrastructure. During the 15th Five-Year Plan period, deep-sea projects will enter a new stage of large-scale development. As core pain points, anti-seepage of concrete structures and seawater corrosion protection impose stringent requirements on materials.

To tackle material protection challenges in extreme deep-sea environments and promote the full-domain application of waterproof and water-retaining technologies in the ocean, Xi’an Maenam Biotechnology Co., Ltd. (hereinafter referred to as Maenam High-Tech) officially announced the establishment of the Maenam Deep Sea Shield Waterproof Deep-Sea Research Group.

The research group will focus on core technical directions including deep-sea high-pressure sealing, long-term anti-corrosion, and compression-resistant water retention. It will continuously iterate and develop new material systems adaptable to complex deep-sea conditions, and build a solid protection foundation for China’s marine engineering, deep-sea development, and emerging marine industries with independently controllable technical strength.

Relying on three independent core technologies—micro-nano physical coating, gradient cross-linking anti-seepage, and active water retention—combined with technological accumulation in terrestrial waterproofing and deep-space water retention, Maenam High-Tech has intensively developed new special waterproof and water-retaining materials for the deep sea. These materials target pain points of deep-sea concrete structures such as leakage, corrosion, low-temperature embrittlement, and high-pressure failure, forming a dual "structure + protection" system with deep-sea concrete. Their performance has been continuously verified through third-party testing and real-sea trials.

Micro-Nano Coating Technology: The core material forms a dense protective layer upon contact with water, fitting tightly to surfaces to block the penetration of seawater and chloride ions, preventing steel bar corrosion in concrete structures. It establishes a dual system of structural self-waterproofing plus surface protection, and has currently achieved a high anti-seepage grade of P20 with stable impermeability at a water depth of 200 meters.

Gradient Cross-Linking Sealing Technology: It withstands an ultra-high pressure of 76.9MPa and tightens further under compression, suitable for key components such as deep-sea concrete sealed cabins and pipeline interfaces. It operates stably within a wide temperature range of -50℃ to 250℃, solving industry pain points of low-temperature embrittlement and high-pressure leakage in traditional materials, especially for self-waterproofing and sealing of concrete structures in extreme deep-sea temperature and pressure environments.

Active Water-Blocking Technology: It achieves in-situ water blocking and pressure retention, synergizing with deep-sea concrete to maintain internal humidity and pressure balance, preventing concrete cracking from water seepage and damage from pressure imbalance. It also enhances concrete’s erosion resistance, and combined with the performance advantages of low-carbon high-corrosion-resistance marine concrete, further extends the service life of structures.

Relying on mature technologies and product reserves, Maenam High-Tech’s new waterproof and water-retaining materials continue to provide core material support for fields including deep-sea scientific research, energy development, marine infrastructure, and mineral exploration, with broad application prospects extendable to numerous emerging marine practical scenarios.

Submarine Tunnels & Immersed Tunnels: Adopting micro-nano waterproof membranes + Maenam High-Tech new waterproof materials to resist ultra-high water pressure of hundreds of meters and high chloride salt erosion, prevent concrete cracking and leakage, ensure tunnel structural stability, improve safety levels, and reduce later repair costs.

Cross-Sea Bridges, Artificial Islands & Breakwaters: Inorganic corrosion-resistant waterproofing synergizes with deep-sea concrete to enhance structural impermeability, protect steel bars from corrosion, extend the design service life of artificial islands and breakwaters to over 100 years, and meet engineering needs in harsh coastal environments.

Offshore Oil & Gas Platforms, Wharves & Docks: Structural self-waterproofing resists corrosion from crude oil and chemicals, suitable for concrete foundations of offshore oil and gas platforms and wharf concrete structures. It maintains elasticity at a low temperature of -50℃ with bidirectional self-tight sealing, a leakage rate ≤1×10⁻⁶ std cm³/s, and reduces operation and maintenance costs.

Submarine Pipelines, Utility Tunnels & Underwater Repair: Maenam High-Tech new waterproof materials are used in filled concrete pouring for waterproofing, shock absorption and fixation, suitable for deep-sea laying to resist ocean current pulling and geological settlement. They also assist underwater concrete repair projects to achieve rapid plugging and protection, improving engineering durability.

The application scenarios of Maenam High-Tech’s deep-sea concrete and deep-sea series products are continuously expanding, with their core value increasingly prominent. They adapt to the diversified development needs of "emerging marine industries", achieve full-scenario coverage from offshore to deep-sea areas, and boast broad application prospects.

Lu Wei, Chairman of Maenam High-Tech, stated: "The successful R&D of 'Mars Water-Retaining Sand' has proven our ability to preserve 'the water of life' in deep-space environments. Today, Maenam Deep Sea Shield Waterproof will guard every drop of seawater resources and hope in the deep sea."

The establishment of the Maenam Deep Sea Shield Waterproof Deep-Sea Research Group represents not only a technological upgrade but also the continuous output of technologies applied as an "ocean guardian", injecting strong Xi’an strength into human deep-sea survival and the development of the blue economy.

With "serving national strategies and empowering marine engineering" as the core, the Maenam Deep Sea Shield Waterproof Research Group will base itself on actual engineering needs. It has currently achieved excellent performance of P20-grade anti-seepage and 76.9MPa compression resistance, providing reliable protection solutions for current medium and shallow deep-sea projects.

In the future, we will continue to deepen technological R&D with the core goal of "breaking through kilometer-level deep-sea protection", continuously iterate and upgrade product performance, further enhance anti-seepage, compression resistance, extreme temperature-pressure resistance and corrosion resistance, and break through protection technical bottlenecks in deeper seas.

By then, our products will adapt to broader application fields in kilometer-level deep seas, unlock new possibilities for deep-blue engineering, provide more reliable, efficient and comprehensive material support for China’s deeper and wider deep-sea exploration and development, help elevate China’s marine power strategy to a new height, and jointly draw a new blueprint for deep-sea industrial development.
