No dewatering
Eliminate the need to drain dams, canals and reservoirs before installation.
REMOTELY OPERATED
UNDERWATER INSTALLATION SYSTEM
UNDERWATER INSTALLATION SYSTEM
Underwater geomembrane installation
A remotely operated system for installing SIBELON™ geomembrane liners on submerged infrastructure without draining the structure or interrupting operations.
The challenge
Install underwater. Keep infrastructure operating.
Installing large geomembrane liners on submerged hydraulic structures requires precise positioning and secure anchoring while water continues to flow and the infrastructure remains operational.
Continuous operation
Maintain hydropower generation and essential water operations throughout the work.
Large-scale positioning
Precisely deploy extensive geomembrane liners across submerged surfaces.
Current resistance
Secure reliable anchoring in underwater currents of up to 1 m/s.
Installation quality
Deliver consistent placement and long-term waterproof performance underwater.
Minimal disruption
Reduce shutdowns, project downtime and environmental disturbance.
