The geotextile performs two primary functions when used in the construction of tunnels:-
1. Protection of the linear from abrasion and puncture by protrusions from the base surface of the tunnel well.
2.Drainage of water seeping through the rock and sprayed concrete layer. The in-plane oermeability of the geotextile enables the water to flow to a subsurface drainage collection system. where it is directed awa from the tunne
The GEOWEB system offers design flexibility for unpaved roadway surfaces, base stabilization, road shoulders as well as erosion protection of embankments and stormwater drainage channels. The 3D GEOWEB structure offers strength improvements to the road base layer for asphaltic and concrete pavements far greater than delivered by geogrids. A single GEOWEB layer performs well over soft subgrades - while geogrids require 2-3 layers for the same benefit - saving cost and construction time. Unpaved roads built with...
