Construction products detail
Strengthening and repair of timber structures
Reaction resin concretes or reaction resin mortars are used for strengthening and repairing timber structures, where applicable in combination with textile-reinforced rebars.
Regulatory framework
DIBt grants general construction technique permits (aBG) for strengthening and repair methods for timber structures, also in combination with national technical approvals (abZ) for the products used ('combined decision').
European Technical Assessments (ETAs) can also be issued for construction products that are used for strengthening and repair of timber structures. As yet, no European Assessment Documents (EADs) have been developed as an assessment basis for this product group.
The execution of each construction project must be inspected by a recognised inspection body in accordance with the Directory of recognised testing laboratories, inspection and certification bodies (PÜZ-Verzeichnis), Part V, no. 8.
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.
