The article presents the research of horizontal ceramic drainage with various geotextile materials and glass fiber sheets to protect drainage from silting on slightly water-permeable loamy soils. Drainage modules were obtained within the range of 0.02-0.4 l/s * ha at a calculated value of 0.6 l / s * ha (the drains were covered with excavated soil). According to preliminary data, the brands of geo-textiles Typar®SF20 (DuPont), PNMPEV-I-125C ("Gronema" Ltd), PNM-PPV-T-150 with hydrophilic additives (PINEMA Jsc) are the most suitable for dehydration of slightly water-permeable soils.
