Geotube® Containers

Overview

Geotubes are used to dewater sludges and for holding sand in place in shoreline applications.

Geotube® units or containers are fabricated with special high strength woven geotextile and are a very cost effective option in dewatering applications, dredging and shoreline protection applications.  The high strength geotextile allows Geotube® units or containers to be manufactured large enough to hold over 900 cubic metres of material each. 

Typical sizes for Geotube® units range from circumferencs of  2.3 metres to 27.4 metres and lengths from 30 metres to 60 metres. Other sizes are available.

In dewatering applications,Geotube® units or containers are filled using sludge slurry with a high concentration of water in order to allow for easy pumping. The excess water then filters through the walls of the soil tube leaving the solids trapped inside the unit. This reduces the amount of high cost liquid material to be disposed leaving solids that are easily handled.

Geotube® units used in hydraulic applications can prevent the erosion of shorelines, and in some cases restore lost shorelines as well. Geotube® units can also be used to reclaim entire islands that are being lost, due to wave action from increased shipping traffic.  In shoreline applications, Geotube® units are typically installed with a scour apron which connects the large unit to a smaller anchor tube.  After filliing, the Geotube® unit can then be covered with sand, rock or spray on coatings.  In offshore or underwater applications, the Geotube® units or containers can be placed within a steel positioning frame, lowered to the required seabed or lake bed bottom location and then filled. 

In dredging applications, such as for shipping lanes, the use of Geotube® units or containers provides a containment of dredged materials to prevent them from returning to the dredged area. This eliminates the cost of having to dredge the same area again. The Geotube® units or containers are typically filled with sand slurry taken from the dredged area.
