CLASSIFICATION OF GEOTEXTILES

Previously to the classification we must clarify the meaning of some terms used frequently for geotextiles:

NON WOVEN

The fibers that make up the geotextile are placed randomly (Do not have two directions of fiber).

WOVEN

The fibers have two directions (warp and weft)

CONTINUOUS FIBER

Non woven geotextile fibers belonging to the final product are infinite.

CUT FIBER

Belonging to the finished fibers have a certain length.

NEEDLEPUNCH

The union between the fibers of the non woven geotextile is a mechanical bond by means of needles that go in and out at high speed.

CALENDERING

The union between the fibers of the non woven geotextile is a thermal bonding where the fibers pass through two calenders.

NEEDLEPUNCH + THERMOTREATED

The union between the fibers of the non woven geotextile is a mechanical bond by means of needles that go in and out at high speed, with a subsequent thermofusing creating the continous fiber in the final product.

WOVEN GEOTEXTILE GEOTESAN LF

WOVEN GEOTEXTILE GEOTESAN LF

Woven geotextile of polypropylene to use as separation layer.

WOVEN GEOTEXTILE GEOTESAN WATERPROOF LF

WOVEN GEOTEXTILE GEOTESAN WATERPROOF LF

Woven geotextile of polypropylene with a coating of liquid polypropylen for use as impermeable layer in vials works.

ANTI CRACK NON WOVEN GEOTEXTILE CR

ANTI CRACK NON WOVEN GEOTEXTILE CR

Geotesan CR is a non woven geotextile, 100% polypropylen virgin fibers bond mechanically by a needlepunch process.

Are use to prevent fissures and cracks from appering over time in the roads and vials creating a intermembrane between the old pavement and the new layer of agglomerated.

NON WOVEN GEOTESAN NT

NON WOVEN GEOTESAN NT

The non woven geotextiles from Geotexan are formed by 100% polypropylen virgin fibers bond mechanically by a needlepunch process and with the subsequent thermofusion that granted high mechanical resistance.

The Geotexan geotextiles can be define by the tasks in the different fields of application.

These include the following:

Separation
Filtration
Drainage
Reinforcement
Protection
