Flexible Waterproofing Protection with Shockmat from Projex

Protecting the waterproofing

Redfern Oval is situated opposite the old South Sydney Leagues Club. The South Sydney Rabbitohs are the oldest club in the ARL competition and the grounds were used for First Grade and other games from 1948 to 1987. The old Grandstand and other fixtures were demolished in late 2006 and in mid 2007 builders moved in to start the reconstruction of the complete facility.

The site posed some real challenges, a major challenge being the high water table which is approximately half a metre below ground level. The change rooms for the home and away teams along with various other service rooms are in the basement, which is 3.5 metres below ground level.

The Wolfin Polyester PVC membrane system was chosen as the waterproofing system for the basement and 5mm thick Projex Shockmat was the preferred protection medium for the completed membrane works.

Projex Shockmat was chosen because a high-strength, robust yet flexible protection medium was needed (one which could withstand the bar reinforcing being dragged over it) and Shockmat fulfilled these criteria. The Shockmat was laid over the membrane below the floor slabs and against the membrane on the outside walls of the basement prior to backfilling.

The Wolfin and Shockmat were installed by Omega Building Services, experienced licensed Wolfin applicators. Wolfin Membranes Australia can be contacted on 02 8336 1666.
