The client wanted a robust, durable and absolutely watertight solution.

Andersal was engaged to waterproofing using Wofin sheet membrane to the upper and lower roof housing the medical isotope nuclear reactor plant.

Special Challenge

There were no handrails on the roof area, so temporary static lines had to be installed. The weather proved to be a problem as each morning we had to wait till heavy condensation evaporated.


  • Andersal laid some 1600m2 of Wolfin S PVC sheet membrane over existing membrane.
  • The project repair was warranted for 20 years.
