WIG PP and GEOWIG PES are geo-nonwovens made of polypropylene and polyester fibres respectively. These are strong and resistant to damage nonwovens.


Geo-nonwovens are available by weight, from 120 to 500 g/m².


Main functions of geo-nonwovens:




This function is based on a takeover of a part of load that originates in the area above the geo-nonwovens. The natural ground base or embankment base of the facilities are covered with the strengthening part.




Protective geo-nonwoven is the layer which intercepts the effect of aggressive substances, entirely or in the part that safeguards the protected area.


The mechanical influences include:

  • wind and water
  • water wave
  • rock spalls
  • perforation



The aim is to prevent the mixing of two substances, especially: of the rubber base with the aggregate, embankment substructure. The basic purpose of separating geo-nonwovens is to avoid reducing the load capacity of the embankment material layer in normal use.




The aim of this function is to enable water to flow and at the same time to prevent silting up of the drainage system by solid particles of the ground.




In connection with impervious composite, the function of geo-nonwovens as the insulating material is connected with blocking liquid medium gravitation flow perpendicularly to the surface of the geo-nonwoven. The typical feature is that water occurs only on one side.


The most known applications are:

  • separation of rubbish from the ground surface to prevent groundwater contamination with the products coming from reactions taking place at municipal and industrial waste dumps
  • separation of the ground surface from water environment in artificial reservoirs
  • separation of engineering construction structures from groundwater
