Yngsjö is Sweden's first prefabricated well superstructure 

Our well superstructure Yngsjö is Sweden's first prefabricated superstructure and protects wells all over Sweden. It is our original model. It has walls of sandwich panels with layer of aluzink. The insulating core is 40 mm extruded polystyrene. The superstructure is mounted on a base which is placed in a gravel bed. In that way the well is provided with an excellent frost-free spacing, easy accessable.
