Non-Woven Geotextile Bag
A non-woven geotextile bag is a type of geotextile bag made from non-woven geotextile fabric. Synthetic fibers are mechanically bonded together without weaving into a traditional fabric structure to form non-woven geotextiles.
Composition and Structure
Synthetic fibers used for non-woven geotextile bags are made from polypropylene or polyester and offer great material properties. The non-woven fabric is produced by mechanically bonding synthetic fibers together without weaving them creating a matrix of intertwined fibers.
This fabric structure may have random or semi-random orientations enhancing its isotropic properties and providing equal strength and performance in multiple directions. Non-woven geotextile bags are designed to have controlled permeability with high-strength threads for seams.
Why use Non-woven Geotextile Bag
Non-woven geotextile bags offer several benefits in their application as identified thus:
- Non-woven geotextile bags can adapt to different site conditions and customized to suit specific project requirements.
- The bags can are resistant to chemical degradation displaying excellent resistance to chemicals present in different soil or water conditions.
- The bags facilitate efficient drainage ideal where water flow management is crucial such as in sediment filtration or dewatering efforts.
- These bags exhibit decent strength and load-bearing capacity thanks to the mechanical bonding process of fibers allowing tolerance of application stresses.
- Geotextile bags made from non-woven fiber are lightweight making their installation and removal non-complicated.
Application
Non-woven geotextile bags are useful in the following applications:
Dewatering – Non-woven geotextile bags find wide usage in dewatering applications where they remove water from sludge and other materials in dredging works and water treatment.
Erosion Control – These bags can be used to stabilize slopes, embankments, or riverbanks preventing soil displacement caused by water flow or wave action.
Filtration – Their ability to allow passage of water while retaining fine particles or contaminants allows their use in sediment filtration e.g. in storm water management and water treatment plants.
Land Reclamation – They are a cost-effective and efficient method for land reclamation in coastal areas and other water body locations.
Retaining Structures – Their ability to provide support and stability during construction and earthworks allows their use as temporary or permanent retaining structures.
Sediment Management – These bags can be deployed to capture sediment in river, ponds, oceans, lakes, or rivers facilitating their removal.
Shoreline Protection – Strategically positioning these bags along coastlines or riverbanks can protect against wave action, stabilize the area and prevent erosion.
