TrapBag Solutions in China
Rapid-Deployment Flood Barriers
China’s vast river systems and monsoon climate make flood control a constant priority. TrapBag® barriers provide a faster, more adaptable alternative to traditional sandbag methods. Crews can install long protective walls in a fraction of the time, strengthening riverbanks, shielding industrial zones, and protecting communities before rising water causes damage. Designed for efficiency, these barriers help minimize disruption while maximizing coverage during emergency response operations.
Learn More »Erosion Control
From the Yangtze River basin to coastal provinces along the South China Sea, erosion threatens farmland, roads, and vital infrastructure. TrapBag® erosion barriers help stabilize these high-risk areas by holding soil in place and absorbing the energy of flowing or tidal water. Their modular design allows engineers to customize installations for riverbank reinforcement, coastal stabilization, or sediment control around development projects.

In China’s mountainous regions, such as Sichuan, Yunnan, and Guangxi, heavy rainfall often triggers dangerous landslides. When filled with concrete or other heavy materials, TrapBag® barriers can act as temporary containment structures to divert debris and mud away from buildings, transportation corridors, and work sites. This flexibility makes them valuable for rapid deployment after storms or earthquakes when time and safety are critical.

Deadly Floods & Flash Floods
TrapBag® barriers offer rapid, scalable protection during emergencies—helping reduce damage to transportation networks, farmland, and populated regions.
Landslides & Mudflows
Heavy rains often trigger landslides in China’s southern and western provinces. TrapBag® systems can divert or slow debris flow, helping to protect villages, roads, and critical infrastructure.
Typhoons & Worsening Monsoon Seasons
Increasingly intense typhoons and longer monsoon seasons bring storm surges and widespread flooding. TrapBag® barriers can be deployed in advance of major storms to protect coastal communities and vital assets.
Why Choose TrapBag?
-
Reliable Strength
TrapBag® is made from high-strength woven polypropylene designed to endure China’s varied climate conditions, from humid coastlines to arid plateaus. The material resists UV degradation, tearing, and abrasion, allowing barriers to perform reliably in both temporary and semi-permanent installations.
-
Efficient Design
Each TrapBag® unit features a pentagonal structure that concentrates roughly 60% of its total weight in the lower section. This unique geometry provides natural stability, reducing the risk of tipping or displacement under pressure from fast-moving water or shifting terrain.
-
Fast Deployment
TrapBag® systems are engineered for rapid setup. A two-person crew with a small excavator or skid steer can install approximately 30 meters (100 feet) of barrier in about an hour. Compared to the labor-intensive process of laying sandbags, TrapBag® dramatically reduces setup time while providing consistent, reliable protection for large-scale projects.
How TrapBag® Compares to:
Sandbags have been used to block floodwaters for thousands of years. However, they’re labor-intensive and have a high margin of error that makes them give way relatively easily compared TrapBag®, which improves on their design.
These barriers are designed to create enough weight and pressure to divert floodwaters from buildings and infrastructure on dry land. However, most water barriers aren’t more than a few feet tall and can’t repel wave action.
TrapBag barriers start at 1.2 meters tall and can be stacked on top of each other during major flooding events. Their solid fill design provides stability and resilience against severe wave action.
Flood walls and floodgates are frequently used in low-lying or flood-prone areas worldwide to protect at-risk locations from flood damage. While many are permanent, others are temporary and deployed for short-term emergencies. However, they can also be costly and challenging to implement.
TrapBag® offers a more affordable, flexible alternative for temporary or permanent flood protection.
