Geotubes®

Product Description

Mirafi^® Geotubes^® are installed as the core of sand dunes, creating a monolithic structure to protect against high waves and erosion during storms. Upon completion of the installation, the tubes are covered with sand and dune grass is planted. The result is a natural-looking dune and one that will provide long term protection.

Features and Benefits

• Minimum impact on the environment while providing a beneficial use for dredge material.
• Cost. Geotubes^® are a cost effective alternative when compared to traditional construction materials and methods.
• Fabrication. Geotubes^® are fabricated from a high strength woven geotextile with special high strength seaming techniques to resist pressures during pumping operations.
• Applications
• Groynes
• Breakwaters
• Sand DuneCores
• Containment Dikes for Dredge Material
• Shoreline Protection
• Wildlife Habitats
• Wetland Construction
• Dewatering of fine grain material

Design Considerations

TC Mirafi^®’s Geotube^® system uses a woven geotextile that is formed into a tube. The tube’s diameter and length are determined by project requirements. The tube is filled by direct coupling to a hydraulic pumping system conveying dredged material.
Designed with appropriately sized openings, the geosynthetic tube retains fill material while allowing water to permeate through the tube wall. Geotubes^® permanently trap granular material in both dry and underwater construction.
