Wolfin waterproofing membranes were recommended as a solution to resolve the water ingress problem in the podium area of the National Library of Australia.

Located on the southern shore of Lake Burley Griffin, Canberra, the National Library housed over six million items in 2001. GHD was engaged by the client in late 2005 to provide a long term solution to water ingress, which was occurring through the podium slab into the library areas below. The brief also required the areas below the podium to remain dry during and after the refurbishment work.

The well-proven Wolfin waterproofing membrane system was specified for the project with temporary shedding constructed to cover about 2,500sqm of the work areas. GHD coordinated with several trades during the implementation of the regimented works program.

Upon completion of the membrane works by Wolfin Membranes Australia, each deck area was flood tested for a minimum of 72 hours before handover to the builder and then to the client after the original slate tiling was reinstated.

Wolfin membranes are available in Australia from Projex Group .
