ABSTRACT
In the engineering constructions there are used biodegradable geotextiles, that are performing primarily a function of surface anti-erosion protection. Their biodegradability supports the development of vegetation, and protects the surface of the slope from the moment of installation in the ground. In order to achieve this functionality there are used mainly biononwovens and woven fabrics made of natiral fibers. In the paper there are presented results of studies on the effect of the instalation of the biononwoven (Maliwatt type with grass seeds) applied in real conditions at a specified time (from November to June), on the selected physical, mechanical and hydraulic properties , and the development of vegetation (grasses). The experiment adopted two versions of instalation of nonwovens. In the first case geotextile was mounted directly on the ground, in the second additionally have been covered with a layer of native soil.
