1. Vysok\u00e1 pevnos\u0165 v \u0165ahu<\/strong><\/p>\n

Jednou z charakteristick\u00fdch vlastnost\u00ed oce\u013eovo-plastov\u00fdch kompozitn\u00fdch geomre\u017e\u00ed je ich vysok\u00e1 pevnos\u0165 v \u0165ahu. Pevnos\u0165 v \u0165ahu je pre geomre\u017ee k\u013e\u00fa\u010dov\u00e1, preto\u017ee ur\u010duje ich schopnos\u0165 odol\u00e1va\u0165 za\u0165a\u017eeniu bez poruchy. Pod\u013ea r\u00f4znych \u0161t\u00fadi\u00ed m\u00f4\u017eu tieto geomre\u017ee dosahova\u0165 pevnos\u0165 v \u0165ahu presahuj\u00facu 50 kN\/m, v\u010faka \u010domu s\u00fa vhodn\u00e9 na pou\u017eitie pri ve\u013ekom za\u0165a\u017een\u00ed, ako s\u00fa dia\u013eni\u010dn\u00e9 a \u017eelezni\u010dn\u00e9 stavby.

2. Trvanlivos\u0165 a odolnos\u0165 proti kor\u00f3zii<\/strong><\/p>\n

Trvanlivos\u0165 je pri stavebn\u00fdch materi\u00e1loch prvorad\u00e1, najm\u00e4 ak s\u00fa vystaven\u00e9 drsn\u00fdm podmienkam prostredia. Kompozitn\u00fd charakter oce\u013eovo-plastovej geomre\u017ee zvy\u0161uje jej odolnos\u0165 vo\u010di kor\u00f3zii, UV \u017eiareniu a teplotn\u00fdm v\u00fdkyvom. Z v\u00fdskumu vypl\u00fdva, \u017ee pri zr\u00fdchlen\u00fdch testoch poveternostn\u00fdch vplyvov si tieto geomre\u017ee zachov\u00e1vaj\u00fa svoju \u0161truktur\u00e1lnu integritu po\u010das dlh\u0161ieho obdobia, pri\u010dom v re\u00e1lnych aplik\u00e1ci\u00e1ch \u010dasto presahuj\u00fa 25 rokov o\u010dak\u00e1vanej \u017eivotnosti. T\u00e1to dlh\u00e1 \u017eivotnos\u0165 nielen\u017ee zni\u017euje n\u00e1klady na \u00fadr\u017ebu, ale minimalizuje aj potrebu \u010dastej v\u00fdmeny, \u010do vedie k celkovej \u00faspore n\u00e1kladov na projekt.<\/p>\n

4. Jednoduch\u00e1 in\u0161tal\u00e1cia<\/strong><\/p>\n

Proces in\u0161tal\u00e1cie oce\u013eovo-plastovej kompozitnej geomre\u017ee je jednoduch\u00fd, \u010do z nej rob\u00ed preferovan\u00fa vo\u013ebu pre mnoh\u00fdch dod\u00e1vate\u013eov. \u013dahk\u00e1 povaha materi\u00e1lu u\u013eah\u010duje manipul\u00e1ciu a zr\u00fdch\u013euje \u010das in\u0161tal\u00e1cie.
