Prestressed precast slab/in situ concrete systems
These floor systems are composed of prestressed precast slabs finished with a structurally contributing in situ concrete overlay.
Regulatory framework
DIBt grants national technical approvals (abZ) for precast slab/in situ concrete systems which are not (fully) covered by DIN EN 13747.
European Technical Assessments (ETAs) can also be issued for precast slab/in situ concrete systems which are not (fully) covered by DIN EN 13747.
If there are no conclusive technical rules for the design and application of the precast slab/in situ concrete system, a general construction technique permit (aBG) may need to be taken into consideration.
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
- Do you significantly deviate from the Technical Building Rules?
- Or do neither Technical Building Rules nor generally recognised technical rules exist?
- 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.
