SYSTEM OVERVIEW

The Fatra retention tank system provides unrivalled performance when installed in a water storage tank environment. The Fatrafol 803vs is designed to create a full bladder system and can withstand continuous stagnant water without failing or delaminating prematurely.

The Fatrafol 803vs is designed to withstand aggressive water pressure, hydrostatic pressure and creates a radon barrier to prevent the natural gases that are present below ground from entering the building foundations. The Fatrafol 803vs is made with a black scrim below and a top yellow signal layer to enable contractors to easily identify any breaches in the membrane. If the yellow top layer is damaged the black scrim layer below shows through making any defects easy to spot and patch repair prior to filling the retention tank.

The Fatrafol retention tank system is completely hot air fusion welded which doesn't rely on tapes or sealants to prevent water ingress. The membrane can be mechanically fixed or bonded using the relevant Fatrabond contact adhesive and can be installed over almost any substrate with minimal preparation and does not require any priming to enable the system to operate efficiently.
