Construction products detail

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

A national technical approval (abZ) and/or oder general construction technique permit (aBG) is granted upon application (see Model Building Code (MBO), Sections 16a(2) and18(2) and (4)). This also applies to amendments and supplements to, or renewals of existing approvals and/or construction technique permits.

No formal requirements apply. The following information is needed: name and address of the applicant, description of the product and/or construction technique and its field of use or application, type of decision required (new decision, amendment or supplement to, or renewal of, an existing decision).
