Parliament House – Balcony Waterproofing Works


The heritage listed Parliament House, built in the 19th century, had water ingress issues as a result of degraded waterproof membrane on the terraces. This was causing internal damage and degradation of the sandstone structure. All existing membrane and copper flashings were removed, and a new high performance sheet membrane was installed. The existing copper flashings were reinstated where feasible with new copper flashings installed where necessary. Repairs were also carried out to the existing sandstone.  All works were completed while the building was fully operational.
