The Sotkon semi-underground containers have the same components of the Sotkon underground systems. The same concrete bunkers are manufactured using prefabricated moulds, providing items with perfectly controlled dimensions and completely watertight.
The cover can be fitted with hinges which allow it to open, turning on the respective rim of the concrete bunker to an angle close to 90 degrees. The cover is opened by means of a key. The basic effort of opening the cover is undertaken by two gas spring cylinders.
Externally different finishing design can be implemented. The cover is produced in polyethylene and designed in order not to allow the entry of liquids.
