Sealants for drains

Sealants for drains serve to prevent, in connection with pipework parts such as pipes and fittings, the leakage of discharged waste water. In the case of underground drains, the sealant also ensures that surrounding groundwater cannot penetrate into the drain.

Regulatory framework

Sealants covered by the relevant harmonised standard series DIN EN 681 or by DIN 4062 do not require additional regulatory verification of fitness for use.

For sealants that are not covered by a harmonised standard (e.g. DIN EN 681 series) or a European Technical Assessment or a technical rule listed in the Technical Building Rules (cf. MVV TB, Section C.2.12.1), DIBt grants national technical approvals (abZ), also in combination with a general construction technique permit (aBG) for the application.

European Technical Assessments (ETAs) can also be issued for the corresponding construction products. For sealants that are covered by a European Technical Assessment, a general construction technique permit for the application may be pertinent.

Please note the relevant provisions of the federal states following the MVV TB, in particular Section B 2.2.6 'Property drainage systems' and Section C 2.12.1 'Pipes, fittings and sealants for drains and sewers'.

For the assessment of the above-mentioned construction products and techniques within the framework of the national procedures, DIBt prepares application-specific test plans. DIBt approval principles and preliminary test programmes form the basis for this. These are compilations helping to speed up the procedure.

The approval principles and test programmes in this work area are not published, but are made available to the applicants during the procedure. To date, the following compilations are available:

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.
