The article describes the results of investigation which studied structure of geotextile and other materials to prevent drainage siltation. Sizes of elementary fibers and micro pores are found as well as its optimal parameters for strong filtering properties what improve the structure of geotextile PNM -PEV-I-150-C, Ltd Grodno nonwoven materials. Process of wettability of porous materials using Voshborn sorption method is described. Requirements for protecting filtering materials for drainage are formulated considering study which are not belong to standard list of ISO 1980-2009
