Driven piles made of ductile cast iron tubes
Driven piles made of ductile cast iron pipes are displacement piles and are used when soil strata have no or little load-bearing capacity. The piles transfer the loads to lower strata with higher load-bearing capacities. The piles are assembled from tubes made of ductile cast iron and are then filled with concrete. The segment lengths are joined together via a coupler integrated into the ductile cast iron tube.
Regulatory framework
The design and execution of applications (construction techniques) with driven piles made of ductile cast iron tubes is non-regulated. For relevant applications falling under the Building Codes, DIBt grants general construction technique permits (aBG), in combination with national technical approvals (abZ) for the products used, where needed. European Technical Assessments (ETAs) can also be issued for these construction products.
The executing company must submit a declaration of conformity stating that the executed construction technique complies with the provisions of the relevant construction technique permit.
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).

European Technical Assessment (ETA)
To start the ETA procedure, please submit the form below. We will then check if the prerequisites for issuing an ETA are met, i.e., in particular, if the product is not fully covered by an existing harmonised standard. If the prerequisites are met, we will check whether a European Assessment Document (EAD) covering the requested assessment scope already exists or still needs to be developed. If an EAD needs to be developed or amended, a complete technical file needs to be established before the procedure can begin.
