Purpose: to analyze the physical and mechanical features of various geotextiles and to justify their use in the construction of impermeable canal coatings to improve the efficiency of reclamation systems in Turkmenistan.

Materials and methods. The objects of the study were needle-punched nonwoven fabric made of polypropylene (PP) and polyester (PET) with a density of 200–600 g/m². The methodology was based on laboratory tests of the surface density, breaking load, coefficient of permeability and light-resistance of the materials under conditions simulating the climate of Central Asia.

Results. It was found that needle-punched nonwoven fabric with a density of 300–400 g/m² are the most effective for the arid zone. The use of stabilized polypropylene allows maintaining up to 80 % of the original strength after 500 hours of intense UV irradiation. The use of geotextiles reduces the risk of mechanical damage to waterproofing membranes by 75–80 % and decreases unproductive water losses by 30–35 %.

Conclusions: The implementation of these technologies allows for an extended service life of reclamation structures to 25–30 years. Scientifically sound selection of geotextile structure parameters ensures the stabilization of canal geometry on shifting soils, which is of strategic importance for the sustainable development of agriculture in the region.
