V\u00fdvoj geom\u0159\u00ed\u017e\u00ed \u00fazce souvis\u00ed s v\u00fdvojem geosyntetik.

Tyto materi\u00e1ly se v\u0161ak \u010dasto pot\u00fdkaly s probl\u00e9my, jako je koroze, degradace nebo nedostate\u010dn\u00e1 pevnost.<\/p>\n

Zaveden\u00ed materi\u00e1l\u016f na b\u00e1zi polymer\u016f v 50. a 60. letech 20. stolet\u00ed znamenalo po\u010d\u00e1tek modern\u00ed geosyntetiky.
