Professional-grade coastal defense solutions
Resilient Coastlines and Ecological Defense Systems
By integrating high-performance geosynthetics with biomimetic design, we provide long-life, low-carbon, and environmentally friendly erosion protection solutions for marine infrastructure.
We provide professional geosynthetic materials services
Traditional concrete-hardened coastlines are highly susceptible to erosion under the impact of waves. Our new solution utilizes high-performance geosynthetics, preserving structural integrity while giving the coastline the flexibility of a natural ecosystem.
High Adaptability: Perfectly adapts to uneven seabed settlement.
In-situ Material Source: Supports infilling with local sediment, significantly reducing carbon footprint.
Ecological Benefits: Promotes the habitat of corals, algae, and nearshore organisms.
Offshore breakwater and reef reconstruction
Challenges: Traditional riprap engineering is costly, suffers from stone shortages, and is prone to structural displacement during typhoon season.
Solution: Customized high-strength geotextile tubes are used. Local silt is hydraulically filled in, and the tubes utilize their own weight to form a stable base. Their unique warp and weft weave structure retains sand particles while rapidly draining filling water.
Key Achievements: Overall cost reduction of over 30%, and effective induction of silt deposition, naturally forming a wide protective beach behind the breakwater.
Seawall foundation reinforcement and deep scour prevention
Challenges: Water scouring at the seawall toe is the primary cause of overall seawall collapse, especially on loose, sandy seabeds.
Solution: A reinforced woven geotextile is laid as the core filtration layer, topped with interlocking geotextile-lined concrete geotextile bags. This composite structure effectively drains water and prevents sand erosion while providing a robust breakwater surface.
Key Achievements: The foundation remains stable even under the impact of a 6 m/s current, significantly extending the lifespan of existing infrastructure.
Coastal wetland restoration and "living shoreline"
Challenges: Hard shorelines lead to habitat loss for marine life, and shorelines lack ecological self-regulation capabilities.
Solution: Utilizing three-dimensional geocells to constrain vegetation substrates, combined with eco-bags for slope support. This approach allows plant roots to penetrate the material, integrating the artificial structure with nature.
Core Outcomes: While resisting coastal erosion, it restores mangroves or other coastal vegetation zones, creating a biodiversity-rich "living" defense line.

Common problems of marine engineering geotechnical materials
What is the service life of geotextile bags in a marine environment?
Weiwo's marine-grade geotextile bags are specially formulated with highly effective anti-aging additives. In deep water or in dark environments covered with silt, their lifespan can reach over 50 years; even in the intertidal zone under long-term sunlight, their UV resistance is sufficient to support structural safety for over 15-20 years.
How to choose the right type of geotextile for coastal erosion control?
This depends on the wave energy intensity and substrate conditions of the project. High-strength woven geotextiles are recommended for high-energy scour areas to provide tear resistance; while for areas such as wetland remediation where filtration is important, long-filament nonwoven geotextiles with good permeability should be given priority.
