Earthen construction

Earthen construction comprises construction products, such as earth plasters and earthen boards.

In addition, load-bearing and non-load-bearing walls can also be constructed as rammed earth walls. In this construction technique, the earth is placed and compacted within formwork in layers.

Regulatory framework

Earth plasters are covered by DIN 18947. Earthen boards are covered by DIN 18948. At present, no regulatory requirements are specified for these construction products, as they are of secondary importance for compliance with the requirements for construction works. 

When using earthen boards in areas where requirements apply, e.g., for fire protection, bracing, or fall protection, a verification of fitness for use (national technical test certificate, project-related approval, or general construction technique permit) may be required.

For the design and execution of rammed earth walls (construction technique) the Earthen Construction Rules (Lehmbau Regeln) in accordance with MVV TB n° A 1.2.8.8. apply.

- DIN 18947 - Earth plasters - Requirements, test and labelling

- DIN 18948 – Earthen boards - Requirements, test and labelling

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.
