Coastal shorelines and inland waterways are increasingly impacted by rising water levels, higher waves and more frequent and intense storms. Many of these areas are experiencing serious erosion that is threatening property, infrastructure and natural environments.
Geotube® geotextile systems have been used for over 50 years in a broad range of challenging applications including:
A single Geotube® container is more than 100 feet long and when filled with sand could weigh up to 150 tons. With that much mass, it becomes extremely difficult for waves, debris and ice to shift the Geotube® container. Containers are typically about seven feet wide or more, which enables a wider protection structure that can be constructed much more quickly and at lower cost than conventional rock, timber or steel barriers.
As debris or ice advances towards the shoreline, the elliptical shape of the Geotube® containers can deflect the material and force it up and over the structure. Conventional barriers made of materials such as armour stone or timber face the ice head-on and are often dislodged or heaved up.
Geotube® containers are specially designed for shoreline protection and are manufactured using high-strength polypropylene multifilament yarns that meet several ASTM standards for fabric strength, seam strength, UV resistance and puncture resistance. In extremely demanding applications, Geotube® containers can be further protected with a Geotube® Debris Shield, a polyurea coating, or even a conventional barrier such as an armour stone wall.
Geotube shoreline systems are available in several configurations and sizes. Each one is designed to provide maximum performance, lifespan and ease of installation. Many can also be custom manufactured to meet site specifications.
Geotube containers are filled in-place with a slurry mix of sand and water or locally dredged material. This simple process enables Geotube® containers to be installed much more quickly than conventional approaches such as armour stone or concrete. Once filled and installed, Geotube® containers with crimpled fibers enable soil to become entrapped and help establish vegetation that can further stabilize landscape as part of a “living shoreline” approach.
