A sheet (), preferably for use in the building sector, and in particular, for sealing the shell of a building, comprising a planar sheet body () that has at least one elastic layer as a sealing layer () made of a material of such elasticity and such restoring force that, when the sealing layer () is penetrated by a fastener (), the material of the sealing layer () surrounding the fastening means () encloses the fastener () and provides sealing in the region of the fastener (). Alternatively, the sheet body contains a sealing material which, upon perforation of the sheet body, is able to automatically emerge or swell to an extent sufficient to close or seal the perforation.

A method for the production of a functional layer of a building shell (), whereby the building shell () has a sheathing () on the inside of the building and a large number of rafters () with roof bays () provided between the rafters () and the sheathing (). It is provided, in this case, that the functional layer is applied at least in some places by painting and/or spraying on the outside () of the sheathing (), and an air-tight and/or water-tight foil (), made especially as a vapor barrier, forms after application.

In a foundation assembly, a moisture barrier is placed on a footing and a foundation wall is on the moisture barrier. The moisture barrier thus isolates the foundation wall from the footing. The footing defines a keyway. The moisture barrier comprises a waterproof layer, a bottom layer attached to bottom side of the waterproof layer, and a top layer attached to the top side of the waterproof layer. The waterproof layer blocks passage of water therethrough. The bottom layer is for attaching the moisture barrier to the footing, and comprises a material that attracts water and binds to cement. The moisture barrier comprises a keyway portion sufficiently flexible and configured to fit the keyway in the footing. When the keyway portion fits to the keyway on the footing, it defines a secondary keyway for receiving a key portion of the foundation wall.
