Earthen channels are intended for mechanical protection of installation of engineering networks to be loaded under ground. By its technical parameters those fully replace the earlier used concrete channels. There is possible to use them for additional protection already installed earthen engineering networks. Floor trunkings are supplied with a colour lid. Connected using connectors and folding the lid over, thus interconnecting the individual parts. Strength limit on compression tested on length 300 mm. Earthen channels are manufactured according to ČSN EN 61386-1 and ČSN EN 61386-24.
