Nonwoven Bontec NW0 pages

A TOTAL RANGE OF GEOTEXTILES
The NW range of Staple Fibre Needle Punched and Thermally Bonded
Nonwoven Geotextiles have been designed to offer optimum performance
per unit weight. Their resulting mechanical robustness and excellent hydraulic
properties make them the ideal choice for separation and filtration. Produced on
state of the art equipment, the Bontec NW geotextile range sets standards in
terms of quality and mechanical performance.
Bontec NW facts include:
UniformTensile strengths in all directions up to 45 kN per metre (kN/m) width
CBR Puncture Strengths ranging from 1.1 to 7.5 kN
NW Mechanical Properties that offer maximum strength in all directions
throughout the length and width of every roll
Our unique manufacturing process utilising both mechanical and thermal
bonding processes ensures that the NW range offer superior performance at
lower weight
Waterflows normal to the plane that are generally several times more than that
required by design
A range of consistent opening sizes suited for use in soils ranging from clay to
coarse granular fill.
NW hydraulic properties that stimulate the build up of a natural soil filter in
the adjacent soil and so ensure long term filtration stability.
Available ex-stock in 5.25m wide rolls or other widths to order
Through the incorporation of an NW fabric in a separation/stabilisation design you
can be assured of improved soil bearing capacities and with it a more stable
construction.
Typical applications for NW thermally bonded non woven geotextiles include:
As a general purpose separator for use under site access roads and areas of
hardstanding
As a separation and strengthening layer under new roadways, car parks, industrial
units etc.
As a fliter surround in the construction of a french drain or granular drainage blanket
For separation: to prevent the intermixing of dissimilar soil layers
For filtration: to allow the passage of fluids whilst preventing the uncontrolled
passage of soil
NW Nonwoven Geotextiles play a major role in providing the functions of
separation and filtration in numerous construction applications. In many instances
the NW fabric actually performs both functions in one. A good example being their
inclusion in Railtrack maintenance, where as a separator/filter layer below the track
ballast their use minimises potential track failure from pumping (the upward
movement of fines from the underlying formation to the ballast).
