Coating materials as well as coating and sealing systems in SFH facilities

Coating materials as well as coating and sealing systems are used for sealing collecting trays, collecting rooms and surfaces in storage, filling and handling facilities for substances hazardous to water (SFH facilities). The sealing ensures that no substances hazardous to water can escape into nearby bodies of water. It thus makes an important contribution to facility-based water protection.

Regulatory framework

Coating materials as well as coating and sealing systems fall under the Ordinance on the determination of the suitability of construction products and construction techniques under water law by means of verifications in accordance with the Building Codes of the federal states (WasBauPVO) and under the Ordinance on facilities for handling substances hazardous to water (AwSV).

DIBt grants national technical approvals (abZ) and/or general construction technique permits (aBG) for these products and construction techniques, confirming that both the construction and the water law requirements have been met. The products and construction techniques are thus deemed to be suitable in accordance with Section 63 of the Water Resources Act (WHG).

Please also note the applicable provisions of the federal states following MVV TB, B 4.1 'Technical requirements for stationary systems and system parts in storage, filling and handling facilities for substances hazardous to water' and MVV TB, C 3.8.

For the construction products specified in MVV TB, C 3.8, only a national technical test certificate (abP) is required. Recognised testing laboratories can be found in the Directory of recognised testing laboratories, inspection and certification bodies (PÜZ-Verzeichnis), see column on the right.

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).
