Definitions

  • the present invention relates to a substructure for a floor covering, with a base element that can be placed on a sub-floor, a height-adjustable support element for holding a beam on which the Bodenbe lay can be mounted.
  • EP 2754773 B1 discloses a substructure for a floor covering, in which a block is provided which can be placed on the ground and on which a holder can be attached at different heights.

  • For laying the floor covering between 3 and 10, in particular 4 to 6 basic elements can be arranged per square meter. As a result, the floor covering can be laid floating, so without fasteners that have to be introduced into the subsoil. As a result, a simple installation on a roof can also take place without the roof membrane being damaged.
