Inner linings for drains and manholes
Inner linings are prefabricated elements used for on-site lining of drains and manholes. They usually serve to improve corrosion protection. Inner linings must be fixed durably and tightly to the drainage structure. Drains with inner linings must ensure the safe discharge of surface water and/or waste water from the property at all times. It must also be ensured that no dangers to the sewer system, built over areas or groundwater and soil arise from leaks, deformations or loss of stability.
Regulatory framework
No technical rules for inner linings for drains and manholes have been referenced by the building authorities so far.
In this work area, DIBt grants national technical approvals (abZ) and/or general construction technique permits (aBG). European Technical Assessments (ETAs) can also be issued for corresponding products.
The technical rules to be observed for the installation of drains inside or outside the building include:
- DIN EN 476 – General requirements for components used in drains and sewers
- DIN EN 752 – Drain and sewer systems outside buildings
- DIN 1986 (series) – Drainage systems on private ground
- DWA-A 118 – Hydraulic design and verification of drain and sewer systems
Tests and verifications for the above-mentioned construction products and techniques should be carried out based on test plans prepared by DIBt on an application-specific basis.

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.
