Applications:

CONSTRUCTION OF TUNNELS

In the waterproofing of tunnels the geomembrane must be adequately protected against the risk of puncture and abrasion, in order to preserve its original characteristics of impermeability. The nonwoven geotextiles GEO are installed between the geomembrane and the irregular, rough surfaces of tunnels. GEO can also perform a drainage function of seepage water.

GEO are used in railway, road and waterway tunnels thanks to their characteristics of puncture resistance, protection efficiency, drainage capacity and chemical resistance.




USE OF NONWOVEN GEOTEXTILE:

Protection layer

level of stress according to site conditions example suggested product
(data sheet and specifications)
low/medium: interlayer between the geomembrane and the concrete surface GEO PP AG 400
 
high: protection layer between the geomembrane and highly irregular surfaces GEO PP AG 500
 
very high protection of the geomembrane against the puncturing action of fill material, in the artificial tunnels GEO PP AG 700
