Woven Geotextiles

(Polybrane® Series):

Polybrane® woven geotextiles are part of a wide range of woven polyproplene materials supplied by Synthetic Packaging Ltd. in Ireland.

Their mechanical and hydraulic properties make them ideal for a wide range of geotextile applications. In a woven geotextile such as a Polybrane the fibres or tapes are aligned in two principal directions and it is the tape itself which resists the stresses directly, giving these geotextiles their characteristic high tensile strength.

The apparent opening size of Polybrane woven geotextiles (150 µm to 500 µm) has been designed to retain the larger particles in the filter zone. The pore size of a nonwoven geotextile is generally smaller(40 µm to 150 µm).

Also as Polybrane geotextiles offer high tensile strength at low elongation their use should offer maximum reinforcing effect with minimal deformation of the construction layers.

As the most efficient filtration results from the formation of a natural soil filter, the spread of pore size distributions available in the Polybrane® series makes them ideally suited to initiate the natural filtration process, and with its higher tensile strength as compared to the non-woven series, the Polybrane® series is ideally suited for use in seperation, filtration, reinforcement and protection applications.
