Geotextile

Geotextile (Dornit) is an environmentally safe, geosynthetic, non-woven material made of endless polypropylene or polyester fibers by needle punching or die cutting—ensuring its high chemical resistance and resistance against various chemical compounds (alkalis, acids).

Key properties

• With high elastic modulus, geotextile can withstand significant loads and reinforce a structure with lower deformations.
• Optimal extension upon breaking and elasticity do not result in destruction, so the material saves its functionality.
• Versatile filtering capability due to geotextile's specific structure prevents intrusion of soil particles into the pores and, thus, clogging. This ensures stability of the filtering function under soil pressure and strong vibration.
• High tear and punching shear resistance.
• UV radiation resistance prevents formation of any by-products harmful to the environment.
• High chemical resistance and resistance to thermal-oxidative aging, fungi, and mold extend the material's service life.
