Geotextile & Impermeable Liner:



Geotextiles have a long history of use in filtration, sub-soil drainage, separation layer and protection applications.


Rainsmart Solutions Supplies® nonwoven needle punched Hydrophilic Geotextile which is polymer based products that are manufactured from a variety of processes. Generally for sub-soil drainage needle punched non woven Geotextile is most suitable type of Geotextile that should be selected for use. The polymers offered are polypropylene or polyester.


Nonwoven geotextiles are manufactured from the extrusion of fibres which are then laid down on a manufacturing "bed" and then needle punched to entangle the fibres such that a dimensionally stable product is formed. Some additional thermal treatment is then applied to further improve the strength of the geotextile. Because of this manufacturing process non-woven Geotextile are generally best used in applications of drainage, filtration and protection.


Nonwoven geotextile of 180 gsm+ minimum in weight with respective parameters in strengths, flow rate, pore size and filtration characteristics are generally recommended by Rainsmart Solutions in conjunction with its drainage products applications.
