More than 350 people attended the meeting of the MICA Action Group, which heard it would only be a matter of time before a house collapses.
The group was formed to take action against defective blocks which are causing homes across Donegal to crumble just years after they were built.
The meeting heard that an estimated 2,000 homes may be affected by the blocks, which were manufactured between 1985 and 2010.
