Flood & Erosion Protection




products (3)



The TrapBag® Flash flood protection barrier is designed for rapid and low-cost deployment to control floodwater, mudslide prevention, and redirection , and erosion control and infrastructure protection. The TrapBag® system is a continuous cellular barrier of pentagon-shaped Barrier bag Cells with a common flexible portion separating each individual cell. Each cell is sloped on one side, vertical on the other, and open on top for filling. They are connected side by side like an accordion, typically in 50-foot-long segments, as tall as 6 feet and up to any height when stacked. Each segment comprises 15 common-partitioned bags or cells. These segments are linked together to create barriers of any length from 50 feet to many miles. Once linked together the segments are filled with one of a multitude of products such as sand, gravel crushed stone or concrete.

To make a semi-permanent or even permanent structure the TrapBag Barrier can be filled with concrete. An easy solution without having to make all the necessary preparations of the location, which normally has to be done for conventional constructions.

City Flood Protection 06


TrapBag® is a low cost, rapid deploy flood and erosion control barrier bag similar to, yet superior than, conventional sandbags. Our bags are designed to protect life and property from natural disasters such as flash flooding, mudslides, mud flows, levee breaches and storm surge. TrapBag is versatile and may be used for other kinds of protection from security barriers to storm-water control.

TrapBag is a series of pentagon-shaped bags that are sloped on one side, vertical on the opposite side and open at the top for filling. Each of the cells are connected side by side like an accordion, each cell has a common wall with the next cell, and are collapsed during storage and deployment. The cells are made of high-strength textile. Each of the cells are self-contained yet rely on the next cell for added strength. If one of the cells is compromised, it will not affect the rest of the barrier, which will remain standing strong.

Trapbag® uses 40% less fill material than a stacked sandbag wall, but more importantly one 100 foot section of 4 foot high TrapBag replaces approximately 8,000 sandbags making TrapBag barrier bags an excellent alternative to small and large sandbags.

Product Specification

The TrapBag Barrier models TBS and TBR

TrapBag Flood and erosion control Barriers are produced in 3 different heights for Metric as well as for English/US dimensions.

TrapBag  barriers provide safety and security from flooding,mudflows ,storm surge, soil and coastal erosion.

The 2015 introduction of  new TrapBag models TBR 60 and TBR 120 with a RIGID partition wall between the cells or compartiments to be able to drastically reduce the installation time, because these can be set up WITHOUT using the installation kit.

TBR 60 Flood Version 


For several models we offer the option to supply with a double front fabric layer (DL) or with a cover to close the top.

The DOUBLE LAYER OPTION will give a longer life in more severe conditions where the barrier is more often exposed to water and sun.

With the CLOSING COVER OPTION the filling material cannot be washed out, which will maintain the best functionality and longer lifetime of the complete barrier.
