Coastal & Waterways
Terram Geosynthetics are commonly used in many coastal and waterway applications such as:
Foreshores, dams and flood bunds, river and canal banks, lagoon, lake and reservoir shores, culverts and outfalls, ports, breakwaters, artificial islands and causeways. Terram Defencell geocells for temporary flood protection are used where a fast response and local fill materials are available.

Application Function
In addition to the more conventional use of geotextiles in coastal and waterways’ engineering, Fiberweb Geosynthetics manufactures a geocellular system for temporary flood defences.
The TERRAM geocellular system was originally developed for military defences. However, the US Corps of Engineers conducted tests with the system to determine whether it could be used to construct temporary flood defences. Their work concluded that the system significantly outperformed sandbags in terms of installation/removal time, water seepage control and overall endurance.
The Terram system is fabricated using a geotextile to form a series of interconnected cells which can be laid flat to form a compact unit for shipment. Once on site, the units are quickly unpacked, opened out, positioned, secured to each other and then filled with a locally-won fill or an imported fill such as sand. The units can be placed on top of each other to form taller structures and the resulting walls can be formed with angles and curves.
On-site installation can be carried out by unskilled labour and the learning curve is short and shallow. Installing at a rate of 20 plus units/hour within three hours of starting - the equivalent protection afforded with 22,196 sandbags – is typical.
