Mixing of backfill of the pipe drain construction with sub-ballast layer material through using enclosed drainage systems (mostly by pipe drains) has to be prevented. In order to do so, regulation SŽDC S4 Železniční spodek provides a filtration criterion which needs to be fulfilled or a geotextile with filtration function has to be used. This master thesis verifies if filtration criteria are fulfilled in between different backfilling of the pipe drains and sub-ballast layers in compliance with TNŽ 73 6949. Furthermore a verification of filtration function of different geotextiles including propositions of their suitable placement within construction of the pipe drain system is included.
