Use & Purposes
Protection layers, typically heavy mass non woven geotextiles, such as Profab® Ultra are used in geosynthetic engineering to reduce the occurrence of local stresses and thus to control potential puncture of the liner by the material installed directly above, typically an aggregate drainage layer.
ProFab® Ultra Geotextile, when used as a protection layer acts as a cushioning barrier between a geosynthetic lining system such as in a dam or landfill cell. Defending the geomembrane from any damage from external forces coming into contact with the liner and reducing local stresses is imperative . This ability to act as a protection layer enables structural fill and base courses to maintain their reliability for longer periods of time. It is therefore paramount that the correct nonwoven needle punched geotextile cushion is specified, selected and then installed.
Consideration needs to be given in the design of a landfill system to:
