Construction products detail

Metal sealings for collecting devices

Metal sealings are installed in collecting devices made of concrete to make them liquid-tight.

Liquid-tight collecting trays and devices are enclosures serving to meet the requirement for secondary containment under water law. They are used to catch and retain substances hazardous to water leaking from storage tanks and pipes.

Regulatory framework

DIBt grants general construction technique permits (aBG) for metal sealings confirming that both the construction and water law requirements have been met. The 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 the Model Administrative Provisions – Technical Building Rules (MVV TB).

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).
