Geocell Systems is a company specializing in research and development, marketing, manufacturing and distribution of modular sand-confinement grid systems. Its products are at the forefront of a flood-fighting revolution that will see slow, labor-intensive sandbag techniques replaced by faster, structurally superior methods during flood emergencies.

The first series of modular sand-confinement systems introduced by Geocell is called the Rapid Deployment Flood Wall (RDFW). All that is needed to achieve protection is native sand, RDFW, a small number of untrained volunteers, and a tractor- or wheel-loader. Building flood walls with RDFW is more than 65 times faster than building sandbag walls, and results in much stronger flood barriers.

Tests have demonstrated that an emergency flood situation once thought to be uncontrolable can now be remedied in a timely manner. In most cases, construction of flood walls with RDFW is at least 65 times faster than with sandbags, while the strength of an RDFW wall has proven to be substantially greater than that of a sandbag structure. RDFW is a proven, effective flood-fighting tool.
