8 Ton PET Rock Bag Filler Unit
The 8Te PET Rock Bag Filter Unit is our ultra-heavy-duty marine erosion control system, specifically engineered for maximum ballast mass in deepwater offshore, high-wave coastal, and heavy civil scour protection projects. Manufactured from high-tensile, virgin Polyethylene Terephthalate (PET) netting, this massive 8-tonne capacity unit encapsulates graded stone aggregate into an unyielding revetment matrix designed to withstand extreme hydrodynamic forces, storm surges, and high-velocity shear stress.
Built for critical infrastructure protection with a design life exceeding 50 years, the 8Te PET Rock Bag is fully UV-stabilized, highly resistant to mechanical abrasion, and non-degrading in harsh marine and saline environments. Its open-mesh flexible structure allows hydraulic energy to dissipate through the unit while conforming seamlessly to uneven subsea trenches, riverbeds, and coastal slopes.
Featuring a certified, single-point heavy-lift ring, the 8Te PET Rock Bag allows for rapid, pinpoint placement via marine vessel cranes or heavy site excavators with zero underwater curing time—eliminating costly and hazardous diver intervention. Over time, the porous matrix traps drifting silts and sediments, encouraging natural marine colonization and micro-habitat creation. Ideal for subsea pipeline and cable stabilization, port and harbor quay wall armor, offshore wind farm scour protection, and heavy riverbank toe defense.
