PNW - Protection

PNW - Protection

A UV stabilized, needle punched, nonwoven geotextile produced from 100% polypropylene staple fibers.

USES & FUNCTIONS

Used in many civil engineering and building applications. Designed to offer protection, filtration, separation, and erosion control functions.

FEATURES & BENEFITS

Mechanical properties with tensile strengths from 5 kN/m to105 kN/m, and CBR puncture strengths from 1.5 kN to 14 kN.
Hydraulic properties with water flow rates normal to the plane from 20 l/m2/sec to 180 l/m2/sec allowing for quick release of water pressure and opening sizes from 50 to 130 mm that accommodate all soil types.
Maximum widths of 5.4 m for jumbo rolls and varying widths based on client's needs.
Available in standard 100 m length jumbo rolls or mini roll lengths of varying sizes.
Weight between 100 and 2000 gr/m2.

APPLICATIONS

In road, railway, drainage, and protection applications. It acts as separator to prevent the intermixing of the different soil layer types, as filter to allow the flow of fluids while preventing the passage of soil particles and as protective layer for geomembranes in landfills. Its protective features make it also suitable to be used in archaeological sites, in order to protect discoveries during excavation works. Several PNW products are successfully being used at the recently found tomb in Amphipolis (Northern Greece).
