Tassie Hall, Galt Collegiate Institute

Cambridge, Ontario (1852)


The Building:
A Collegiate auditorium


Project Synopsis:
The 200-seat high school auditorium, added in the 1930s, has a vaulted ceiling, comprised of expanded metal lath and cement-based plaster, which had been severely damaged by continued water infiltration.

A survey conducted by HPCS indicated that if we could consolidate the plaster on the existing rusted lath, it would then be possible to apply a new layer of lath where required and bond it to the improved plaster using HPCS GR Non-Shrink GroutTM .

Consolidation was carried out with repeated penetrating spray applications of HPCS  CO S-20 and CO S-50 Primers, followed by CO R-100 Consolidation Agent. The water-damaged plaster readily absorbed the resins and on evaporation, the ceiling was sound and much improved. Re-supporting it required the introduction of new expanded metal lath. This was successfully completed and the building remains a landmark in its community.
