Geotextile durability reinforcement

The membranes can also be reinforced to improve the durability of the material and prevent over-elongation of the membrane. Other t5q>es of materials and membranes are available and a specific assessment should be made where these materials are proposed (e.g. liquid applied membranes and aluminium bonded to geotextile membranes). The disadvantages and points to consider for various types of membrane are provided in Table 7.3. 

Geotextile fabrics are based on woven, nonwoven and composite fabric structures whose properties are determined primarily by the fiber/yarn components present in terms of intrinsic tensile properties and chemical durability. Most geotextiles are expected to have lifetimes well in excess of 20 years and to provide varying degrees of mechanical reinforcement and containment to the civil engineering structures in which they are incorporated. 

Coir-based geotextiles have both the benefits of biodegradabihty and durability required for the slow establishment of vegetative cover. Various open-weave coir geotextiles are employed in erosion control for reinforcement and embankment applications. Typical functional specifications for a woven coir geotextile are ...
