Placing new waterproof sheets
Introduction
A geotextile or geofabric is a permeable and flexible fabric of synthetic fibers, mainly polypropylene and polyester, which can be manufactured in a non-woven (non woven) or woven form (woven) depending on its use or function to be performed.
A large number of geotextiles are manufactured with the most varied characteristics:
Geotextiles according to their manufacturing method
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:
Types of geotextiles
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.
