TrapBag® Flood and Erosion Control
Rapid-Deployment Flood Barriers
Emergency crews can deploy TrapBag® flood barriers faster and more effectively than traditional sandbags ahead of hurricanes and other major storms.
Designed to handle immense pressure, these barriers keep floodwaters away from infrastructure, neighbourhoods, and natural areas. For towns and businesses across the Cayman Islands, TrapBag® is a faster, stronger, more strategic approach to flood protection.

Erosion barriers from TrapBag® are designed to preserve coastal areas and vulnerable riverbanks with ease. They protect homes and buildings on the waterfront from coastal erosion and prevent soil or beach loss that puts livelihoods at risk.

Who We Serve In Cayman Islands
TrapBag® can be a life, environment, and property-saving multipurpose barrier for multiple industries.
Emergency Management
Every second counts when a storm is approaching. Emergency management crews trust TrapBag for fast, reliable flood protection.
These barriers can be deployed in a matter of hours, while offering better defence than traditional sandbags.
Learn More »Marine Services
Ports, marinas, and offshore facilities in the Cayman Islands need protection, especially Grand Cayman’s tourist spots. As stackable barriers, TrapBag® can withstand the ocean’s wave action and minimize the harmful effects of erosion on these structures.
Learn More »Coastal & Civil Engineering
Arterial roadways, water treatment centres, and other infrastructure are vulnerable to damage during coastal flooding and storm surge events. TrapBag® is a safe, cost-effective way to protect these structures and prevent millions in damage.
Learn More »Environmental Protection
The Cayman Islands’ beaches, ponds, and dunes are at risk of disappearing due to increasingly severe storms and persistent wave action.
TrapBag® can provide temporary or permanent protection during severe storms to prevent coastal habitats from washing away.
Learn More »Construction & Infrastructure
TrapBag® is an effective detention system on construction sites because it’s just as good at keeping water in as it is at keeping water out.
Your construction sites will comply with stormwater and runoff regulations when you use TrapBag® as a detention pool or pond.

Yearly Hurricane Risks
As low-lying islands, Grand Cayman, Little Cayman, and Cayman Brac are particularly vulnerable to damage during tropical storms and hurricanes. While communities throughout the territory are no strangers to hurricanes, these storms are getting worse every year.
TrapBag® was designed with protecting these communities in mind. These barriers are stackable and can withstand severe storm surges to protect property and lives.
Beach Erosion & Degradation
Hurricanes and tropical storms are also causing beaches throughout the territory to disappear. For example, Tropical Storm Helene has reduced Seven Mile Beach to almost nothing in some areas. Beach nourishment, sand retention, and dune core stabilization are necessary to keep this famous beach and others like it from disappearing forever.
Archipelago-Wide Flooding
Even during normal storms or heavy rains that roll in from the Caribbean, the Cayman Islands are at risk of flooding. Low-lying areas are common, and drainage systems may not be able to keep up, so additional protection may be necessary to keep residents and their properties safe.
Why Choose TrapBag®?
-
Fast Deployment
A small team consisting of two individuals and someone operating a skid steer or small backhoe can complete a 100-foot (approximately 30-metre) TrapBag barrier within one hour. This gives precious time back to emergency crews to get others or themselves to safety.
-
Reliable Strength
TrapBag uses geotextile technology to hold back tons of water pressure and keep people and properties in the Cayman Islands safe. Each cell supports its neighbours when you fill it with sand, washed gravel, or concrete.
This also helps it withstand localized damage if a single cell is compromised—unlike traditional sandbag walls, which can collapse altogether and compound flooding disasters.
-
Efficient Design
Every TrapBag® flood barrier cell is engineered with a pentagonal shape that concentrates 60% of its mass in the bottom half. It enables less labour-intensive installation when time is running short and weather conditions are severe.
Compared to other temporary barriers, TrapBag® offers a more secure, efficient option for large-scale flood response and infrastructure protection.
-
Tried & Tested
Over 1,000 miles of TrapBag® have been installed worldwide as erosion control and temporary flood protection barriers. Tested by the United States Army Corps of Engineers and relied upon by state and municipal governments worldwide, they are a proven system for protecting councils, neighbourhoods, and entire towns across the UK from flooding.
How TrapBag Compares to:
Sandbags have been a traditional method of blocking flood waters for thousands of years because they’re affordable but effective barriers. However, their high margin of error and labour-intensive building process make them less practical than TrapBag®.
TrapBag® is more cost-effective and protects more lives than traditional sandbag walls because it’s less likely to give way when you need it most.
Most water-filled barriers are only a few feet high and cannot be used to withstand wave action. TrapBag® barriers begin at 4 feet tall. Once you have filled and placed the base rows, you can stack more on top. They have an interlocking design and solid fill that stabilises the entire barrier.
Floodgates and flood walls can be installed as either temporary or permanent structures in flood-prone and low-lying areas in the Cayman Islands. However, these can be expensive and challenging to install.
TrapBag® is a more affordable, flexible alternative that can be used for short- or long-term flood protection in any emergency response situation—especially when time and budgets are limited.
