HERMEQ supplies Vetter Inflatable Drainage Blockers—high-performance pipe sealing bags used for isolating drainage systems during emergencies, maintenance, or containment procedures on US job sites. These stoppers inflate inside pipes, drains, or sewers to block liquid flow or hazardous runoff, preventing environmental contamination and backflow.
Ideal for fire departments, utility crews, civil contractors, or environmental teams. Each unit inflates with compressed air and forms a leak-tight seal at pressure ratings up to 2.5 bar (36 psi). No tools or adhesives required.
Common Use Cases:
- Preventing toxic or flammable leaks from entering stormwater systems
- Isolating pipelines for maintenance
- Containment during washdowns or fire-fighting
