We bought Mavis Avenue when it already had concrete cancer in the classrooms. Damien showed me that it is also now in the corridor upstairs in the north? wing. Apparently residents had been overwatering pot plants for a long time and the water continued to flow into the concrete there.
Damien says that Wayne Thompson, who served on the EC but was then recruited to the Bendigo Stupa board, is a retired engineer. Apparently Wayne has retired from the engineering firm he owned but may be a good source for help. I don't see his name listed as a TI member. I don't know him, myself but do you?
