Plastic/sealing sheets and membranes for use in storage, filling and handling facilities for substances hazardous to water (SHF facilities) are manufactured to a specific thickness, laid loosely on the prepared substrate and welded to form a walk-on collecting room seal. 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

Plastic/sealing sheets and membranes in SFH facilities and linings made of them 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 used in storage, filling and handling facilities for substances hazardous to water'.
