Dredging Spoils Containment Systems

GeoTextile Tubes are being used successfully around the world as a depository for Hurricane Storm Protection dredging spoils. The dredging materials such as silt and sand are pumped directly by dredge discharge pipes into geotextile tubes until the tubes are filled to capacity. The Geotextile tubes are then left to dewater. After dewatering, the remaining materials can be ported to other locations for use in beach renourishment and land reclamation. Using GeoTextile tubes to collect the dreging spoils is a cost effective means of disposing of the spoils as opposed to the older method in dredging of building a "Containment Cell" to pump the dredged material into. The Cell must first be dug into the chosen area, the land cleared, before it can be used, and the cost to build the cell is far more expensive than employing GeoTextile Tubes. The containment cell material must then be dispersed, usually by truck, to the areas wishing to use the material.

Dredging Spoils used in Breakwaters

Another growing system being used around the world for disposal of dredging material uses GeoTextile tubes as the receiver of the dredged spoils. However, this system involves placing the tubes in Hurricane Storm Protection permanent, designated areas in bodies of water such as marinas or bays and pumping directly into the tubes to form a breakwater, sometimes stacking tubes in a pyramid shape to reach a higher breakwater. Use of GeoTextile tubes for breakwaters has proven very effective against unwanted wave action that affects beaches and marinas. Breakwater tubes are estimated to have a life expectancy of at least 10 to 20 years. The life expectancy of a GeoTextile breakwater can be extended greatly by armoring the breakwater with "Articulating Block Concrete Mattresses", some engineers estimating up to 50 years or similar lifespan to riprap breakwaters.

Dredging Spoils for Beach Erosion

SDMI dba Caribbean GeoTextiles use of filled geotextile tubes and bags placed along coastal beaches for Hurricane Storm Protection to slow down beach erosion has proven to be very effective as well as cost effective. Additionally, geotextile bags can be used in a sand color to match the surrounding beach area and blend into the environment.
