Ansto Lucas Heights

Wolfin membrane to the roof

Client: ANSTO (Australian Nuclear Science & Technology Organisation)

Location: Lucas Heights, Sydney

Task: To waterproof the upper and lower roof housing the medical isotope nuclear reactor plant.

Andersal Site Supervisor: Eddie Issa

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.
  • Security was tightly controlled.


  • The client wanted a robust, durable and absolutely water tight solution.
  • Andersal laid some 1600m2 of Wolfin S PVC sheet membrane over existing membrane.
  • Andersal and Projex warranted the repair for 20 years.
