Marine construction faces the constant threat of crushing ocean tides pulling fine sand out from beneath heavy rock armor, leading to seawall collapses. Our marine-grade woven geotextile underlayment is engineered to survive this extreme hydraulic stress. Placed beneath massive coastal boulders or concrete breakwater units, this rugged marine filtration fabric functions as a highly durable filter barrier. It allows violent wave backwash to drain back into the ocean freely, eliminating internal water pressure, while firmly holding back the underlying sand bed. For intertidal land reclamation boundaries, harbor docks, and marine coffer dams, this robust interlocking geotextile sheet provides permanent coastal erosion defense.

Technical Specifications

Why Choose Our Woven Geotextile?

• True High-Tensile Interlock: Our advanced weaving looms weave continuous long filaments incredibly tight, ensuring the fabric locks soil particles in place immediately without pre-stretching.
• Immune to Marine Salt Decay: The pure polymer filaments are completely immune to saltwater chemical degradation, marine micro-organisms, and barnacle oil rot.
• Maintains High Flow Under Loads: Our specific mesh openings are engineered to never clog or blind over, venting high sea-wave pressures smoothly even under the weight of heavy rocks.
• Resists Crushing Rock Drops: The dense weave features extreme bursting resistance, meaning it can absorb the heavy impact of large boulders dropped during seawall construction without splitting.

Primary Applications

• Coastal Rock Seawall: Installed directly under massive granite armor stones to stop crashing ocean waves from pulling sand out through rock gaps.
• Harbor Quayside Dock: Lining the earth retention walls behind concrete shipping berths to filter heavy tidal water fluctuations without loss of land.
• Temporary Coffer Dam: Placed under temporary soil and rock barriers in river deltas to prevent the river current from scouring away the dam foundation.
• Intertidal Land Reclamation: Serving as the bottom boundary blanket before pumping sea sand, preventing the valuable fill from washing away into the deep ocean.
