Pile couplers

Pile couplers are used for connecting segments of prefabricated foundation piles when the required pile length exceeds the maximum as-delivered lengths.

Regulatory framework

Pile couplers are usually regulated together with precast reinforced concrete piles in accordance with DIN EN 12794 or together with other piles through national technical approvals (abZ) / European Technical Assessments (ETAs) / general construction technique permits (aBG).

DIBt can grant national technical approvals for the individual product 'pile coupler' where necessary. European Technical Assessments (ETAs) can also be issued for these products.

Please also refer to the applicable Technical Building Rules, cf. MVV TB Part A 1.

This also applies to amendments and supplements to, or renewals of existing approvals and/or construction technique permits.

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.
