Waterproofing the Conservatorium
of Music
The Conservatorium of Music adjacent
to Sydney's Botanical Gardens is noticed by everybody
that comes to Sydney. It is the building in the
middle of Macquarie Street that looks like a medieval
castle or small palace.
| The NSW Government decided some
years ago that it required a complete upgrade and
accordingly work was commenced in 1999.
The existing building was substantially
upgraded but in addition a new building (Verbruggen
Hall) was added. This building is actually four
separate four-level structures each separated by
50mm of air space.

The waterproofing of the structure
was considered to be a critical component of the
building process by the NSW Department of Public
Works and Services, the NSW Government Architect
and the architects Darryl Jackson Robin Dyke.
The waterproofing was made more
difficult than usual because of the placement of
12,000 m2 of gardens and landscaping over the structures.
The Wolfin System was chosen because
of its ability to be used in landscaping projects
and permanently damp situations and its proven track
record on Public Works projects.
Wolfin S self-adhesive membrane
was laid under the garden beds, Wolfin GWSK was
laid under the asphalt in the front driveways and
Wolfin AF6 profile was cast into the concrete prior
to membrane installation to form a termination for
the sheet membranes themselves. All areas were watertested
prior to being signed off.
Wolfin's combined materials and
labour warranty was issued to the Department of
Public Works and services. In essence this warrants
not just the performance of the Wolfin System but
that the structure is waterproof. Wolfin were able
to issue this warranty because they had been involved
in the waterproofing design from the beginning and
also carried out formal on-site inspections every
few days to "sign off" the areas as they
were completed. This is a standard Wolfin procedure
which is carried out on all Wolfin jobs.
The installation was carried out
by Andersal Engineering, experienced licensed Wolfin
Applicators, in both remedial and new situations.
