GI-Tube is a large geosynthetic tube made of 2 layers of special Non-Woven geotextile material. Each GI-Tube elements is very innovative and environmentally friendly. The outer part of non woven serves to catch the surrounding sand so that this material can be protected naturally. GI-Tube fill material should be sand, that can be obtained easily in large quantities around the coast or river. Mechanically, sand is a stable element and have a very low shrinkage coefficient after installed on site.
Advantages of GI-Tube :
- Has a very small opening size, the permeability of the material is good enough to immediately discharge water inside, this means the installation process can be done very easy and fast
- Flexible (it can follow shoreline and soil contours) and has a very high durability
- Environmentally friendly, does not cause pollution, it can even blend with the surrounding environment when moss and sea plants have grown on the surfaces
- Can be produced in various sizes as needed
GI-Tube has been proven superior to be applied in in Hydraulic Engineering, as follows :
- Coastal protection from abrasion
- Return of coastline lost due to abrasion
- Beach/ coastal reclamation
- Protection of water structures
- River normalization
In addition, GI-Tube can also be used for Environmental Engineering as :
- Sludge packing (industrial process waste material)
- Dewatering mud in a pond / lake / river
- Livestock and agricultural waste filters
