Balmain Shipyard

BCS was appointed in 2012 to reduce saline water flow through the sandstone joints of the iconic Balmain Shipyard.

Constructed in 1890, the shipyard is carved in sandstone with concrete beams and walls. As specialists in the waterproofing of natural stone and concrete structures, BCS were able to deliver a range of solutions for this project.

The bedding layers of the sandstone were injected with a specialist membrane material which provided a flexible layer within the rock strata and stopped the seepage of saline water through the rock joints. It also created a waterproofing membrane which was an innovative solution and more effective than shotcreting.
