Fabrics: the mesh is woven with fibers in two directions (weft and warp). They can be:

Nonwovens: randomly interwoven fibers linked by mechanical, thermal or chemical processes with continuous filament. They can be:

Mixed: the mesh is made up of chopped fibers.

They can be:

The needle cut fiber geotextiles not subjected to the thermofusion process are materials with minimal mechanical resistance, since as there is no union between their elements and they are not linked together, they can be easily perforated when a perpendicular force is applied since their fibers open without offering resistance, at the same time the traction forces separate them, unlinking them.

Heat-welded geotextiles only have no thickness, their elongation is less than needle-woven ones.

The needle continuous filament geotextiles, or needle and heat-welded geotextiles, have high mechanical resistance to prevent breakage, they also have adequate thicknesses to fulfill their drainage function, anti-weed geotextile function, geomembrane protection function and cushion effect function.

El geotextil es una malla compuesta por fibras sintéticas cuyas funciones principales se basan en su resistencia mecánica a la perforación y tracción, y a su capacidad drenante.

Sirven en la construcción de sub-bases de carreteras y ferrocarriles, en presas, evitan posibles erosiones realizan funciones de drenaje en canales, muros de contención, etc.

Los geotextiles sirven para separar tierras de diferente granulometría estabilizando el terreno, para protección de láminas impermeabilizantes.

Los geotextiles pueden desempeñar distintas funciones:.

Separation

The separation prevents contact between two surfaces with different physical properties, which prevents their mixing and contamination although it allows the free flow of liquids by filtering them through the geotextile, it can be between two different layers of supplied soil or between natural and supplied soil.

To avoid mixing of materials, it must withstand the static and dynamic loads of the filler material and traffic during placement, as well as the retention of fines. The polypropylene keeps it stable against the alkalinity of the cement and inert against the various chemical elements present in the ground.

The following aspects must be taken into account in the separation function:

• - Tensile strength.

• - Puncture resistance.

• - Elongation at break.

• - Dynamic drilling by free fall of cone.

• - Effective pore opening.

• - Thickness of the geotextile.

Filtration

Filtration is the property of a material retaining certain particles subjected to hydrodynamic forces while allowing the passage of fluids. The filter function must ensure its hydraulic stability.

In this filtration function the following parameters must be taken into account:.

• - Permeability.

• - Effective opening of pores.

• - Thickness of the geotextile.

Drainage

Drainage is the process by which a fluid (liquid or gas) is moved from one place to another, evacuating it. In this way, elimination is carried out by evacuation in the thickness of the geotextile without producing the washing of fines.

In this drain function the following parameters must be taken into account:.

• - Permeability in the plane of the geotextile.

• - Thickness of the geotextile.

Booster

The reinforcement of the geotextile is achieved by the properties that certain geotextiles possess, improving their mechanical properties and reducing the level of loads on the ground because it does the job of homogenizing the loads over an extensive surface.

We consider two types of reinforcements:

1. • Strengthening traction, eliminating overturning forces. For example: in retaining walls, by inserting the geotextile towards the interior of the wall.

2. • Soil stabilization by confinement of particles, evacuating the contained water by suppression.

In this reinforcement function, the following parameters must be taken into account:.

• - Deformation curve.

• - Mechanical resistance to traction, punching and tearing.

• - Creep, fatigue and friction against the ground. It also helps to improve the quality of soil support.

Protection

The protection function allows the geotechnical system not to deteriorate. The geotextile acts by protecting waterproof geomembranes; so that it prevents mechanical damage from abrasion or puncture.

In this protection function, the following parameters must be taken into account:.

• - Puncture resistance.

• - Dynamic drilling by free fall of cone.

• - Thickness (cushion effect to protect the geomembrane).

• - Agricultural thermal blanket.
