Other floor and wall construction techniques

DIBt grants general construction technique permits (aBG) for floor and wall construction techniques which significantly deviate from the Technical Building Rules or for which no generally recognised technical rules exist.

DIBt grants national technical approvals (abZ) for innovative and other non-regulated construction products used in wall construction techniques.

European Technical Assessments can also be issued for construction products within the meaning of the Construction Products Regulation (Regulation (EU) No 305/2011) upon request.

Regulatory framework

Please also refer to the applicable provisions at federal state level, in particular the Building Code of the relevant federal state and the associated Technical Building Rules. You can find the relevant model provisions (MBO and MVV TB) under 'Legal references' in the column on the right.

Note: The lists below may still include approvals for a construction technique, also called 'application approvals'. As a result of the revision of the Model Building Code (MBO) in 2016 followed by the revision of the applicable Building Codes of the federal states (LBO), these are successively being replaced by construction technique permits or will expire.

National procedure

To prepare an abZ/aBG for your construction product, we need an application from you. We recommend that you contact us prior to doing so. Feel free to send us your enquiry informally via email to dibt(at)dibt(.)de or to the competent technical contact listed in the top right.

For a first assessment, please send us the following information:

  • Description of the construction product and its intended field of use
    • e.g. material, configuration, number of sizes, variants, dimensions
    • e.g. use in walls, ceilings, interior construction, building services
  • Description of the construction technique and its field of application
    • e.g. design of walls, ceilings, elements, etc., and interaction of components
    • e.g. application in foundation engineering, reinforced concrete construction, building insulation; as load-bearing or non-load-bearing component; under static and quasi-static loading; fire exposure; other environmental exposures
  • Information regarding impact on regulatory concerns
    • in particular structural integrity, fire protection, health and environment protection, sound insulation as well as thermal performance
  • Explanation of need for an abZ/aBG
  • Contact details
    • preferably email address and/or telephone number, as well as name, organisation/company, and postal address

We will then contact you to clarify the next steps.

If you already hold a DIBt approval and/or construction technique permit and wish to apply for an amendment, supplement, or renewal, please use the form provided below.
