SYSTEM OVERVIEW

The Fatra retention tank refurbishment 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 gives the client the opportunity to install the membrane over the existing failed membrane depending on the condition of the existing membrane which drastically reduces the cost and program of the project.

Unlike traditional liquid applied systems which require extensive preparation and are affected by numerous variables such as substrate moisture content, an average of 24 hour cure times per coat and inclement weather the Fatrafol PVC membrane system performance and reliability is not affected by any of these issues which cause liquid membranes to fail so often. As the Fatrafol PVC membrane system is a sheet membrane, overlaying finishes can be installed once the installation is complete and signed off.

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 is mechanically fixed and can be installed over almost any substrate with minimal preparation.
